Economically enhanced succinic acid fermentation from cassava bagasse hydrolysate using Corynebacterium glutamicum immobilized in porous polyurethane filler

High yields of fatty acid and neutral lipid production from cassava bagasse hydrolysate (CBH) by heterotrophic Chlorella protothecoides

“…Shi et al prepared the cassava bagasse hydrolysate through combining the liquefaction and saccharification process using a-amylase and glucoamylase and the enzymatic hydrolysis process using cellulase. The CBH contained glucose, xylose and trace amounts of arabinose, acetic acid, and lactic acid (Shi et al, 2014), which was in consistent with our results. Thirdly, the cellulase hydrolysis process was developed by evaluating cellulase dosage and combination with acid pretreatment and amylase hydrolysis.…”

“…In a previous study, a high production of reducing sugars was obtained with hydrothermal and acid pretreatments followed by enzymatic hydrolysis (Gaewchingduang and Pengthemkeerati, 2010). Shi et al reported the preparation of the cassava bagasse hydrolysate by the liquefaction, saccharification and enzymatic hydrolysis process using different enzymes (Shi et al, 2014). Various enzymatic hydrolysis processes, single-step or multi-step hydrolysis, were investigated in this study.…”

Engineered biosynthesis of biodegradable polymers

“…Apart from continuous fermentations, an immobilized fermentation system was studied by Shi et al using C. glutamicum strain immobilized in porous polyurethane filler and using cassava bagasse hydrolysate (CBH) as substrate for succinic acid production. To regulate pH of fermentation medium, mixed alkalis (NaOH and Mg(OH) 2 ) were used instead of NaHCO 3 and a succinic acid productivity of 0.4 g/L/h was achieved from 35 g/L glucose of CBH [160].…”

The industrial applications of cassava: current status, opportunities and prospects

“…In addition to biofuels, it is noteworthy that the fermentation of cassava waste‐based substrates has benefited the production of organic compounds (especially acids). For example, microorganisms such as Aspergillus niger , Lactobacillus plantarum and Lactobacillus paracasei were cultivated on cassava industrial wastes for various purposes, in which different organic acids (including VFAs, citric acid, lactic acid and succinic acid) were produced via biological processes (Table ) …”
