implementation of forward osmosis to concentrate alpha ketoglutaric acid from Fermentation Broth performance and fouling analysis
Journal of Membrane Science, 2021Co-Authors: Mateusz Szczygielda, Martyna Krajewska, Lei Zheng, Long D Nghiem, Krystyna ProchaskaAbstract:Abstract Forward osmosis (FO) was demonstrated as a promising method to concentrate alpha-ketoglutaric acid in Fermentation Broth. Using a model solution containing alpha-ketoglutaric acid, the impact of the initial pH value on water flux, reverse salt flux, and rejection of alpha-ketoglutaric acid were first elucidated. Results from this study show that water flux was not affected by feed solution pH. However, feed solution pH could influence alpha-ketoglutaric acid rejection and reverse salt flux. The highest alpha-ketoglutaric acid rejection of 99.7% and lowest reverse salt flux were observed at pH 5. Multi-component model and real Fermentation Broth were then used to validate FO application for concentrating alpha-ketoglutaric acid. Water recovery of 80% was achieved without severe membrane fouling. In addition, membrane fouling analysis show that the built-up fouling layer of impurities is flaky and of unstable nature, suggesting that membrane fouling could be reversible. Knowledge of the fouling layer formation can contribute to the development of an effective method of pretreatment of the Fermentation Broth and cleaning FO membranes in the future.

removal of succinic acid from Fermentation Broth by multistage process membrane separation and reactive extraction
Separation and Purification Technology, 2018Co-Authors: Krystyna Prochaska, Jerzy Antczak, Magdalena Regelrosocka, Mateusz SzczygieldaAbstract:Abstract An environmentally friendly process for separation of succinic acid from the model solutions as well as the actual post-Fermentation Broth left after bioconversion of raw glycerol (which is generated in a large amount as a by-product during the production of biodiesel) was studied. An integrated system to realize this process was proposed which consisted of: ultrafiltration (UF), bipolar membrane electrodialysis (EDBM) and 3-step reactive extraction (RE) with commercial solvating extractants. Pre-clarification process carried out by UF allowed the removal of high molecular contaminants present in the feed solution, such as: biomass, proteins as well as bacteria cells. Significant reduction in permeate flux during the process was observed due to fouling of ceramic UF membranes. However, the fouling layer was effectively removed by applying hydraulic and chemical cleaning baths. Application of the EDBM process in the proposed integrated system allowed elimination of acidification of Broth which usually generates a considerable amount of wastes. The succinic acid, present in the aqueous stream after EDBM was removed in a three-step reactive extraction at more than 90% efficiency. Extraction can support membrane techniques to separate efficiently carboxylic acids from the post-Fermentation Broth, however, it is not selective enough to separate succinic acid from other acids present in the Broths. The only way to reach selective extraction of succinic acid over acetic, lactic acids and glycerol is to decrease pH to 2 and use Cyanex 923 as an extractant.

separation and concentration of succinic acid from post Fermentation Broth by bipolar membrane electrodialysis edbm
Separation and Purification Technology, 2017Co-Authors: Mateusz Szczygielda, Jerzy Antczak, Krystyna ProchaskaAbstract:Abstract The separation and concentration of succinic acid from 3-component model solutions and actual post-Fermentation Broth after pre-treatment processes were studied in a 10-chamber large-scale EDBM setup. The influence of current density and initial concentration of succinates in the diluate chamber was evaluated by considering such factors as: (i) final succinic acid concentration, (ii) current efficiency and (iii) energy consumption for 1 kg of succinic acid production. According to the results, the highest acid concentration in the concentrate chamber and the highest current efficiency of 75.4% after 180 min of the process were obtained when the current density and the initial concentration of succinic acid salt in the diluate chamber were equal to 120 A/m2 and 200 g/L, respectively. The results have proved that it is possible to use the EDBM process as one of the steps of separation and concentration of succinic acid from the actual post-Fermentation Broth after biotechnological conversion of glycerol. Moreover, it should be stressed that the application of EDBM process allows the concentration of succinic acid and additionally the conversion from salts to the acidic form.

fumaric acid separation from Fermentation Broth using nanofiltration nf and bipolar electrodialysis edbm
Separation and Purification Technology, 2014Co-Authors: Marta Woźniak, Krystyna ProchaskaAbstract:Abstract The suitability of two techniques: nanofiltration (NF) with ceramic membrane and bipolar electrodialysis (EDBM), in separation and concentration of fumaric acid from Fermentation Broth obtained during biotechnological conversion of glycerol, was investigated. The influence of composition, concentration and pH of fumaric acid model solutions on the efficiency of nanofiltration process was studied. It was found that the retention of fumaric salts increased strongly with increasing pH of the initial solution, while the retention of glycerol was lower than 6%, irrespective of pH. In the second step, the influence of electrodialysis stack configuration, current density, pH and concentration of fumaric acid in model solutions on the efficiency of bipolar electrodialysis was analysed. Then, after NF pretreatment, EDBM process of simulated solutions as well as Fermentation Broth was performed. The current density equal to 50 A/m2 was found sufficient to achieve a 53% desalination of fumaric acid from Fermentation Broth. Moreover, the results obtained showed that bipolar electrodialysis stack, consisting of anion-exchange and bipolar membranes, allowed selective separation of fumaric acid from the Broth. The results suggest that NF with ceramic membrane as well as EDBM can be effectively applied as a removal step of fumaric acid from Fermentation Broth.

the final recover of salt from 1 3 propanadiol Fermentation Broth
Separation and Purification Technology, 2010Co-Authors: Hong Jie Ren, Dehua LiuAbstract:Salts are by-products in the 1,3-propanediol Fermentation Broth. The separation technique for 1,3-propanediol generally requires desalting before putting into operation. Previous studies on the downstream processing of biologically produced 1,3-propanediol were mainly focused on the removal of these salts, rather than the recovery of these salts. In this paper, a whole recovery process of salts in the actual Fermentation Broth was discussed. First, batch crystallization was achieved by analyzing the characteristics of this system. Then the process of crystallization was optimized with uniform design. Our studies indicated that batch crystallization can effectively recover sodium succinate from actual 1,3-propanediol Fermentation Broth. The final purities and overall yield of sodium succinate and sodium sulfate were 98.4%, 99.1% and 64.1%, 72.3% under the optimum conditions, respectively.

downstream processing of 1 3 propanediol Fermentation Broth
Journal of Chemical Technology & Biotechnology, 2006Co-Authors: Jian Hao, Hongjuan Liu, Dehua LiuAbstract:The downstream processing of 1,3-propanediol Fermentation Broth using flocculation, reactive extraction, and reactive distillation was studied. Cellular debris and soluble protein in the Broth were flocculated by combined use of chitosan and polyacrylamide at optimal concentrations of 150 ppm and 70 ppm, respectively; the soluble protein in the Broth decreased to 0.06 g L−1, and the recovery ratio of the supernatant liquor to Broth was greater than 99%. 1,3-Propanediol and other alcohols were extracted from the supernatant liquor by reacting with butyraldehyde. In a four-stage countercurrent extraction with the volume ratio of the extraction solvent to the aqueous phase being 20:100, more than 99% 1,3-propanediol acetal (2-propyl-1,3-dioxane) and 2,3-butanediol acetal (2-propyl-4,5-dimethyl-1,3-dioxolane) were recovered from the aqueous phase; 35% of the glycerol acetals were recovered. The acetals produced were hydrolyzed in a reactive distillation column using the strongly acidic cation-exchange resin as catalyst, the bottom product obtained was a mixture of 1,3-propanediol (407 g L−1), 2,3-butanediol (252 g L−1), glycerol (277 g L−1), and glycerol acetals (146 g L−1).

the possibility of the desalination of actual 1 3 propanediol Fermentation Broth by electrodialysis
Desalination, 2004Co-Authors: Yan Gong, Xiaolin Wang, Yu Tang, Dehua LiuAbstract:Electrodialysis (ED) was employed to remove the organic and inorganic salts from actual 1,3-propanediol (PDO) Fermentation Broth. These salts cause many problems during the purification of PDO if not removed. Suitable operation parameters such as applied potential and the flow rate of streams were selected to ensure a stable and durative desalination process for PDO Fermentation Broth. Under these conditions, the membrane fouling can be alleviated effectively by changing pole and cleaning membranes so that further industrial production is possible. The experiment results show that about 90% of organic acid salts in PDO Broth are removed by the ED process. In addition, a simulated diffusion PDO experiment proved that the diffusion of PDO results in its loss from Fermentation Broth and the loss ratio is less than 6% under the chosen operating conditions.

a novel strategy for salts recovery from 1 3 propanediol Fermentation Broth by bipolar membrane electrodialysis
Separation and Purification Technology, 2011Co-Authors: Ru Chun Wu, Yun Zhen Xu, Yuan Quan SongAbstract:Abstract Desalinization is an important step for the down-stream process of biological production of 1,3-proanediol (1,3-PD). Some literatures on desalinization of 1,3-PD Fermentation Broth are available, but very few ones refer to the recovery and conversion of the salts to high-added value by-product. In this paper, a novel process, including bipolar membrane electrodialysis (EDBM), acid crystallization and base recycling for Fermentation was proposed, which could efficiently recover salts from 1,3-propanediol Fermentation Broth. In this process, EDBM was first employed to obtain the 1,3-PD Fermentation Broth that meets the requirement for later purification process and recovery acids and NaOH from salts. The optimum operating conditions of EDBM were established by response surface method (RSM). Under the optimum conditions, 1,3-PD recovery, energy consumption, current efficiency and conversion rate of salts were 96.0%, 22.69 W h/kg, 98.66% and 85.1%, respectively. By this novel process, industrial succinic acid was obtained and NaOH was successfully recycled to 1,3-PD Fermentation process, realizing the utmost utilization of these salts.

Energy-efficient recovery of butanol from model solutions and Fermentation Broth by adsorption
Bioprocess and Biosystems Engineering, 2005Co-Authors: N. Qureshi, S. Hughes, I. S. Maddox, M. A. CottaAbstract:This article discusses the separation of butanol from aqueous solutions and/or Fermentation Broth by adsorption. Butanol Fermentation is also known as acetone butanol ethanol (ABE) or solvent Fermentation. Adsorbents such as silicalite, resins (XAD-2, XAD-4, XAD-7, XAD-8, XAD-16), bone charcoal, activated charcoal, bonopore, and polyvinylpyridine have been studied. Use of silicalite appears to be the more attractive as it can be used to concentrate butanol from dilute solutions (5 to 790–810 g L^−1) and results in complete desorption of butanol (or ABE). In addition, silicalite can be regenerated by heat treatment. The energy requirement for butanol recovery by adsorption–desorption processes has been calculated to be 1,948 kcal kg^−1 butanol as compared to 5,789 kcal kg^−1 butanol by steam stripping distillation. Other techniques such as gas stripping and pervaporation require 5,220 and 3,295 kcal kg^−1 butanol, respectively.

butanol recovery from model solution Fermentation Broth by pervaporation evaluation of membrane performance
Biomass & Bioenergy, 1999Co-Authors: N. Qureshi, Hanspeter M BlaschekAbstract:Abstract This is an overview of butanol separation from model solutions and Fermentation Broth by pervaporation. It is difficult to compare different authors’ work on butanol separation because of the number of variables involved. These variables include type of membrane, membrane thickness, feed temperature, condensation temperature, vacuum or sweep gas, feed butanol concentration, etc. For comparison we have calculated the butanol concentration in the permeate and butanol flux from the data given by various authors. Polytetrafluoroethylene (PTFE) membrane and polypropylene (PP) membrane pass a large amount of water through the membrane. Fermentation Broth was found to decrease flux and selectivity of a liquid membrane. A silicalite membrane offers high butanol flux and high butanol concentration when using Fermentation Broth. A thin polydimethylsiloxane (PDMS) membrane offers high flux and low selectivity, while a thick membrane offers high selectivity and low flux.

recovery of butanol from model solutions and Fermentation Broth using a silicalite silicone membrane
Journal of Membrane Science, 1999Co-Authors: N. Qureshi, M M Meagher, Robert W HutkinsAbstract:Abstract A silcone–silicalite-1 composite membrane was synthesized to recover acetone, butanol, and ethanol (ABE) from model solutions and the Clostridium acetobutylicum (ABE) Fermentation Broth. The adsorption capacity of the silicalite-1 in the presence of a mixture of acetone, butanol and ethanol were 8–12, 85–90 and 2 h at feed butanol concentrations ranging from 5 to 9 g/l and a retentate temperature of 78°C. A 170 μm silicone membrane under identical conditions had selectivity and flux of 30 and 84 g/m 2 h, respectively. A thin silicalite membrane offered low selectivity and high flux, while a thick membrane offered high selectivity and low flux. The effect of butanol concentration (0.37–78 g/l) on flux and selectivity was also studied.
