Biohydrogen Production by Antarctic Psychrotolerant Klebsiella sp. ABZ11
Lower temperature biohydrogen production has always been attractive, due to the lower energy requirements. However, the slow metabolic rate of psychrotolerant biohydrogen-producing bacteria is a common problem that affects their biohydrogen yield. This study reports on the improved substrate synthes...

The isolate was screened for biohydrogen production at 30°C, under facultative anaerobic condition.
