Enhanced xylitol production: Expression of xylitol dehydrogenase from Gluconobacter oxydans and mixed culture of resting cell
Xiang-Hui Qi, Jing-Fei Zhu, Jun-Hua Yun, Jing Lin, Yi-Lin Qi, Qi Guo, Hong Xu
Highlights
・The properties and kinetic parameter of xylitol dehydrogenase were determined.
・Xylitol dehydrogenase has a NAD(H)-binding motif and a YXXXK active site motif.
・Xylitol production was improved by mixed culture with adding exogenous NADH.
・The highest yield and volumetric productivity of xylitol were reported.

Recovery of laccase from processed Hericium erinaceus (Bull.:Fr) Pers. fruiting bodies in aqueous two-phase system
Devamalini Rajagopalu, Pau Loke Show, Yee Shin Tan, Sekaran Muniandy, Vikineswary Sabaratnam, Tau Chuan Ling
Highlights
・Laccase was successful recovered from processed H. erinaceus in PEG/Salt ATPS.
・Cold-stored of H. erinaceus recorded highest laccase activities (2.02 ± 0.04 U/mL).
・Recovery conditions of laccase in optimized system of APTS contained 17% (w/w) PEG-8000 and 12.2% (w/w) potassium phosphate.
Environmental Biotechnology
Denitrification by Pseudomonas stutzeri coupled with CO2 reduction by Sporomusa ovata with hydrogen as an electron donor assisted by solid-phase humin
Zhixing Xiao, Takanori Awata, Dongdong Zhang, Arata Katayama
Highlights
・Denitrifying co-culture of Pseudomonas and Sporomusa was established.
・Denitrification was coupled with acetogenesis from CO2 with H2.
・Humin increased nitrate reducing capacity of co-culture when acetate was deficient.
・More than 60% of consumed H2 in co-culture system was used for denitrification.
・The co-culture system showed robust denitrification by successive transfer.
