Optimization of biohydrogen production by the novel psychrophilic strain N92 collected from the Antarctica
"In this study, the response surface methodology (RSM) with central composite design (CCD) was employed to improve the hydrogen production by the psychrophilic N92 strain (EU636058) isolated from Antarctica, which is closely related to Pseudorhodobacter sp. (KT163920). The influence of operatio...
