Abstract :

Hydrogen was produced successfully from the solid waste generated during sweet produced from Benincasa hispida using enriched mixed microbial culture. Solid waste was first characterized and chemical oxygen demand was found to be 3000 mg/L having neutral pH. For better hydrogen production and to stop the methanogenesis, microbial culture was pretreated using microwave irradiation having power of 320 W with a frequency of 2450 MHz. Pretreatment was done for different time intervals (1, 3, 5, 7 and 9 min) to optimize the pretreatment conditions. In present study pretreated reactors were compared with a normal or untreated reactor. Maximum hydrogen production was observed when inoculum was pretreated for 7 min (76.4% of total gas produced). SEM analysis was also done to study the effect of pretreatment on microbial culture.
