Original Abstract

Improper lignocellulosic wastes management causes severe environmental pollution and health damage. Conversion of such wastes particularly sugarcane bagasse (SCB) onto bioenergy is a sustainable approach due to a continuous depletion of conventional biofuels. The delignification of SCB is necessary to proceed for bio-genic H2 productivity by anaer-obic bacteria. The effect of autoclaving, pre-acidification/autoclaving and pre-alkalization/ autoclaving of SCB on glucose recovery and subsequently H2 productivity by dark fermentation was comprehensively investigated. Pre-acidified SCB with 1% H2SO4 (v/v) provided H2 productivity of 8.5 +/- 0.14 L/kg SCB and maximum H2 production rate (Rm) of 105.9 +/- 8.3 mL/h. Those values were dropped to 2.7 +/- 0.13 L/kg SCB and 58.3 +/- 12.9 mL/h for fermentation of delignified SCB with 2% H2SO4. This was linked to high levels of total phenolic compounds (1775.3 +/- 212 mg/L) in the feedstock. Better H2 productivity of 13.9 +/- 0.58 L/kg SCB and Rm of 133.9 +/- 3.6 mL/h was achieved from fermentation of pre -alkalized SCB with 1%KOH (v/v). 256.8 +/- 9.8 U/100 mL of a-amylase, 165.7 +/- 7.6 U/100 mL of xylanase, 232.8 +/- 6.1 U/100 mL of CM-Cellulase, 176.5 +/- 5.0 U/100 mL of polyglacturanase and 0.702 +/- 0.013 mg M B. reduced/min. of hydrogenase enzyme was accounted for the batches supplied with delignified SCB by KOH. The Clostridium and Bacillus spp. was dominance and prevalence resulting a higher H2 productivity and yield. A novel strain of Archea and alpha proteobacterium were also identified and detected.
