Improvement of biohydrogen production by Enterobacter cloacae IIT-BT 08 under regulated pH

A comprehensive and quantitative review of dark fermentative biohydrogen production

“…CO 2 can be removed or separated from H 2 , sequentially stored in biomass [29], or converted to other substances, such as CH 4 [30,31]. Basic microbiological investigations and bioprocess engineering research was performed to increase the overall strain performance of BHP during fermentation of pure microorganisms [32-34]. …”

Comparative evaluation of the hydrogen production by mixed consortium, synthetic co-culture and pure culture using distillery effluent

“…However, two mol of hydrogen is formed by butyrate pathway (Das and Veziroglu, 2008). It has been observed that a higher A/B ratio leads to increase in hydrogen production (Khanna et al, 2011). Volatile fatty acid analysis showed higher A/B ratio in the case of C. freundii as compared to other two strains that might be the reason for the higher hydrogen production.…”

“…The FID operational temperatures of the injection port, the detector, and programmed column were 220°C, 240°C, and 130-175°C, respectively. For flame generation, a mixture of hydrogen and air was used at a flow rate of 30 mL/min (Khanna et al, 2011).…”

Role of formate hydrogen lyase complex in hydrogen production in facultative anaerobes

“…The H 2 yield was improved by 31% and that of substrate conversion efficiency by 10%. In case of packed bed reactors having whole cell immobilized system, pH regulation inside the reactor is difficult [56]. Moreover, a non linear variation in pH was observed along the length of the packed bed reactor.…”
