Optimization of ultrasound-assisted dilute acid hydrolysis conditions of tea processing waste
2016 ASABE International Meeting, 2016Co-Authors: Mustafa Germec, Kubra Tarhan, Ercan Yatmaz, Nedim Tetik, Mustafa Karhan, Ali Demirci, Irfan TurhanAbstract:Abstract. Lignocellulosic materials that are the most abundant plant biomass in the world have the potential to become sustainable Sources of the produced value added products. Tea processing waste (TPW) is a good Lignocellulosic Source to produce the value added products from fermentable sugars. Therefore, the present study is undertaken to produce fermentable sugars by using ultrasound-assisted dilute acid hydrolysis of TPW followed by enzymatic hydrolysis. Furthermore, optimization of ultrasound-assisted dilute sulfuric acid (UADA) hydrolysis conditions of TPW was performed by response surface method at maximum power (900 W) for 2 h. Optimized conditions were 50°C, 1:6 (w/v) solid: liquid ratio, and 1% (w/v) dilute acid ratio, which yielded as 20.34 g/L fermentable sugar concentration. In conclusion, ultrasound-assisted dilute acid hydrolysis can be successfully applied for hydrolysis of TPW, which is a favorable carbon Source for numerous value-added product productions via microbial fermentation.

Ultrasound-assisted dilute acid hydrolysis of tea processing waste for production of fermentable sugar.
Biotechnology progress, 2016Co-Authors: Mustafa Germec, Kubra Tarhan, Ercan Yatmaz, Nedim Tetik, Mustafa Karhan, Ali Demirci, Irfan TurhanAbstract:Lignocellulosic materials that are the most abundant plant biomass in the world have the potential to become sustainable Sources of the produced value added products. Tea processing waste (TPW) is a good Lignocellulosic Source to produce the value added products from fermentable sugars (FSs). Therefore, the present study is undertaken to produce FSs by using ultrasound-assisted dilute acid (UADA) and dilute acid (DA) hydrolysis of TPW followed by enzymatic hydrolysis. UADA hydrolysis of TPW was optimized by response surface methodology (RSM) at maximum power (900 W) for 2 h. The optimum conditions were determined as 50°C, 1:6 (w/v) solid:liquid ratio, and 1% (w/v) DA concentration, which yielded 20.34 g/L FS concentration. Furthermore, its DA hydrolysis was also optimized by using RSM for comparison and the optimized conditions were found as 120°C, 1:8 solid:liquid ratio, and 1% acid concentration, which produced 25.3 g/L FS yield. Even though the produced sugars with UADA hydrolysis are slightly less, but it can provide significant cost saving due to the lower temperature requirement and less liquid consumption. Besides, enzymatic hydrolysis applied after pretreatments of TPW were very more economic than the conventional enzymatic hydrolysis in the literature due to shorter time requiring. In conclusion, ultrasound-assisted is a promising technology that can be successfully applied for hydrolysis of biomass and can be an alternative to the other hydrolysis procedures and also TPW can be considered as suitable carbon Source for the production of value-added products like biofuels, organic acids, and polysaccharides. © 2016 American Institute of Chemical Engineers Biotechnol.
