Journal ArticleDOI
Feasibility of biological hydrogen production from organic fraction of municipal solid waste
TL;DR: In this article, a simple model developed from the Gompertz equation was used to estimate the hydrogen production potential and rate from organic municipal solid waste (OFMSW) and two seed microorganisms, namely heat-pretreated digested sludge and hydrogen-producing bacteria enriched from soybean-meal silo.
Journal ArticleDOI
Biohydrogen production as a function of ph and substrate concentration
TL;DR: The conversion of organics in wastewaters into hydrogen gas could serve the dual role of renewable energy production and waste reduction and the highest conversion efficiency was 46.6 mL H2/(g COD/L).
Journal ArticleDOI
Modeling and optimization of anaerobic digested sludge converting starch to hydrogen.
TL;DR: Experimental results obtained emphasize that the response of metabolites was a more useful indicator than hydrogenic activity for obtaining efficient hydrogen production, and expressions of contour plots indicate that Response‐Surface Methodology may provide easily interpretable advice on the operation of a hydrogen‐producing bioprocess.
Journal ArticleDOI
INFLUENCES OF pH AND MOISTURE CONTENT ON THE METHANE PRODUCTION IN HIGH-SOLIDS SLUDGE DIGESTION
TL;DR: In this paper, the effects of pH and moisture content on high-solids sludge digestion were investigated using a mesophilic batch digester fed with sludge cake, and the experiments were carried out by changing the initial moisture contents from 90 to 96% and the initial pH from 5.6-7.8 with an optimum of pH 6.3.
Journal ArticleDOI
Enhanced biohydrogen production from cornstalk wastes with acidification pretreatment by mixed anaerobic cultures
TL;DR: In this article, two predominant bacterial morphologies, namely spore-forming rod shape bacteria and micrococcus were screened, purified, and identified after enriched from a hydrogen-producing fermentor with cow dung composts.
