Integrative Approach for Producing Hydrogen and Polyhydroxyalkanoate from Mixed Wastes of Biological Origin

摘要: In this study, an integrative approach to produce biohydrogen (H2) and polyhydroxyalkanoates (PHA) from the wastes of biological origin was investigated. A defined set mixed cultures used for hydrolysis hydrolysates were H2. The effluent H2 production stage PHA production. Under batch culture, a maximum 62 l H2/kg pure potato peels (Total solid, TS 2 %, w/v) 54 l biowastes (MBW1) recorded. Using biowaste mixture (MBW1), Bacillus cereus EGU43 could 195 mg PHA/l 15.6 % (w/w). Further, supplementation GM-2 medium (0.1×) glucose (0.5 %) in effluents, resulted significant improvements up 11 41.7 % contents, respectively. An improvement 3.9- 17-fold yields as compared with without MBW1 has been This seems be suitable process improve by mixing biowastes.
