combination of zero valent iron and anaerobic Microorganisms immobilized in luffa sponge for degrading 1 1 1 trichloroethane and the relevant microbial community analysis
Applied Microbiology and Biotechnology, 2017Co-Authors: Wenbing WangAbstract:1,1,1-Trichloroethane (1,1,1-TCA), a dense non-aqueous phase liquid (DNAPL), is relatively slow to remediate naturally; combination of zero-valent iron and immobilized Microorganism is a potential means to accelerate DNAPL biodegradation. We first adopted high density luffa sponge (HDLS) as immobilized Microorganism carrier. The experimental results demonstrated that (1) the supernatant liquid Microorganisms were the optimal immobilized Microorganisms for HDLS and (2) the combination of zero-valent iron and immobilized Microorganisms accelerated 1,1,1-TCA transformation. Furthermore, in the long-term remediation process, anaerobic Microorganisms produced reductant H2S which was beneficial to zero-valent iron PRBs. Through further study of the microbial community, we found that majority of the sulfate-reducing bacteria (SRB) perfectly adapted to the process of 1,1,1-TCA co-metabolism dechlorination. Desulfobulbus and Desulfococcus potentially were the special SRB that contributed significantly to TCA co-metabolism. Additionally, 1,1,1-TCA induced the generation of new SRB and stimulated the growth of majority of dominating methanogens. The results indicated that they played a constructive role in accelerating the dechlorination of 1,1,1-TCA, reduction of sulfate, and improving the production of CH4. Consequently, combination of zero-valent iron and immobilized Microorganisms for remediating groundwater by contaminated 1,1,1-TCA is a sustainable and green remediation technology. Especially for groundwater of SO42- type contaminated by 1,1,1-TCA, in the long-term course of combination degradation, cyclic utilization of H2S to prolong the service life of zero-valent iron PRBs. H2 and CH4 generated to capture as potential energy resource. Based on this, a tentative reaction mechanism for Fe0 biodegradation of 1,1,1-TCA was proposed.

Effects of beneficial Microorganisms on lowland rice development
Environmental Science and Pollution Research, 2017Co-Authors: Adriano Stephan Nascente, Alan Carlos Alves Souza, Valácia Lemes Silva Lobo, Thatyane Pereira Sousa, Marta Cristina Corsi Filippi, Anna Cristina Lanna, Gisele Barata Da SilvaAbstract:Microorganisms can promote plant growth by increasing phytomass production, nutrient uptake, photosynthesis rates, and grain yield, which can result in higher profits for farmers. However, there is limited information available about the physiological characteristics of lowland rice after treatment with beneficial Microorganisms in the tropical region. This study aimed to determine the effects of different beneficial Microorganisms and various application forms on phytomass production, gas exchange, and nutrient contents in the lowland rice cultivar ‘BRS Catiana’ in a tropical region. The experiment was performed under greenhouse conditions utilizing a completely randomized design and a 7 × 3 + 1 factorial scheme with four replications. The treatments consisted of seven Microorganisms, including the rhizobacterial isolates BRM 32113, BRM 32111, BRM 32114, BRM 32112, BRM 32109, and BRM 32110 and Trichoderma asperellum pooled isolates UFRA-06, UFRA-09, UFRA-12, and UFRA-52, which were applied using three different methods (microbiolized seed, microbiolized seed + soil drenched with a Microorganism suspension at 7 and 15 days after sowing (DAS), and microbiolized seed + plant spraying with a Microorganism suspension at 7 and 15 DAS) with a control (water). The use of Microorganisms can provide numerous benefits for rice in terms of crop growth and development. The Microorganism types and methods of application positively and differentially affected the physiological characteristics evaluated in the experimental lowland rice plants. Notably, the plants treated with the bioagent BRM 32109 on the seeds and on seeds + soil produced plants with the highest dry matter biomass, gas exchange rate, and N, P, Fe, and Mg uptake. Therefore, our findings indicate strong potential for the use of Microorganisms in lowland rice cultivation systems in tropical regions. Currently, an additional field experiment is in its second year to validate the beneficial result reported here and the novel input sustainability.

Pulsed electric field inactivation of Microorganisms: from fundamental biophysics to synergistic treatments
Applied Microbiology and Biotechnology, 2019Co-Authors: Allen L. GarnerAbstract:The growth of antibiotic resistant Microorganisms and the increasing demand for nonthermal antimicrobial treatment in the food and beverage industry motivates research into alternative inactivation methods. Pulsed electric fields (PEFs) provide an athermal method for inactivating Microorganisms by creating nanometer-sized membrane pores in Microorganisms, inducing cell death when the PEF duration and intensity are sufficient such that the pores cannot reseal after the PEFs through a process referred to as irreversible electroporation. While PEF inactivation has been studied for several decades, recent studies have focused on extending the technique to various liquids in the food industry and optimizing Microorganism inactivation while minimizing adverse effects to the treated sample. This minireview will assess the biophysical mechanisms and theory of PEF-induced cellular interactions and summarize recent advances in applying this technology for Microorganism inactivation alone and synergistically in combination with other technologies, including temperature, pressure, natural ingredients, and pharmaceuticals.

agronomic performance of lowland rice plants promoted by beneficial Microorganisms
Revista de Ciências Agrárias, 2019Co-Authors: Israel Mendes Sousa, Adriano Stephan Nascente, Marta Cristina Corsi Filippi, Anna Cristina LannaAbstract:This work aimed to determine the effect of application forms of growth promoting Microorganisms on tropical lowland rice plants development, in two experiments. EI was performed in completely randomized design (CRD) in factorial scheme 7x3+1. Treatments were six rhizobacteria: BRM32109 and BRM32110 (Bacillus sp.); BRM32111 (Pseudomonas fluorescens); BRM32112 (Pseudomonas sp.); BRM32113 (Burkholderia pyrrocinia); BRM32114 (Serratia sp.) and Trichoderma asperellum pool fungus (UFRA.T06+UFRA.T09+UFRA.T12+UFRA.T52) with three application forms (microbiolized seed; seed + soil drenched with Microorganism at eight and 15 days after sowing (DAS) and seed + plant sprayed with Microorganism at eight and 15 DAS), and control. In EII, microbiolized rice seeds were sowed on test tubes in CRD. Treatments were the same six rhizobacteria of EI and control (water). Isolates BRM32110, BRM32111, BRM32112 and BRM32113 improved gas exchange in lowland rice plants. For biomass production, there were interactions between types of Microorganisms and application forms. In general, microbiolization + plant sprayed was the most efficient (10.3%) to increase dry matter biomass of rice shoots. Stoodout BRM32109, BRM32111 and BRM32113, which, increased, on average, 19% of dry rice biomass when compared to the control plants. Root length of rice seedlings treated with Microorganisms was, on average, 89% higher than control plants.
