Optimization of photo fermentation in corn stalk through phosphate additive

Bioresource Technology Reports, 2019
Abstract Phosphorus is an essential nutrient for microbial growth which effectively influences the bio‑hydrogen production process. In the present study, the effect of phosphate concentration on simultaneous saccharification fermentation (SSF) hydrogen production by phototrophic microbial consortium has been investigated at various initial pH ...

Comprehensive modeling of photo-fermentation process for prediction of hydrogen production

International Journal of Hydrogen Energy, 2017
Abstract Hydrogen production via modern technologies and without using fossil fuels has been found considerably important recently. Photo-fermentation is introduced as one of the most effective methods without high risk for bio-hydrogen production. In this study, comprehensive modeling and simulation of bio-hydrogen production is carried out through ...

Biohydrogen production using dark and photo fermentation: A mini review

2011 National Postgraduate Conference, 2011
Biological production of hydrogen is the most environmental friendly method in producing hydrogen, a clean fuel which produces only water upon combustion. There are many references available on biohydrogen production. This paper presents a review on current biological hydrogen production focusing on dark and photo fermentation processes. Limitation for

Enhanced photo-fermentative hydrogen production by Rhodobacter capsulatus with pigment content manipulation

Bioresource Technology, 2012
High content of pigment in purple nonsulfur photosynthetic bacteria hinders its photo-hydrogen production rate under intense light irradiation. In order to alleviate the light shielding effect and improve its photo-fermentative hydrogen production performance, pufQ, which is the regulatory gene of bacteriochlorophyll biosynthesis in Rhodobacter ...

Enhanced bio-hydrogen production by the combination of dark- and photo-fermentation in batch culture

Bioresource Technology, 2010
In this study, some key factors, for example, diluted ratio of effluents, the ratio of dark-photo bacteria, light intensity and light/dark cycle influencing hydrogen production by combining Clostridium butyricum and immobilized Rhodopseudomonas faecalis RLD-53 in batch culture, were investigated.

Effect of cornstalk hydrolysis on photo-fermentative hydrogen production by R. capsulatus

International Journal of Hydrogen Energy, 2019
Abstract Cornstalk is a typical cellulose material, which can be used by photo-fermentative H2 production after pretreatment. However, the pretreatment methods have different influence on photo fermentation. In this study, 25.0 g cornstalk was pretreated by HCl/NaOH/cellusase. The hydrolysis rates increased from 45.51% by ddH2O-treatment to 60.79% by

Best mode for photo-fermentation hydrogen production: The semi-continuous operation

International Journal of Hydrogen Energy, 2016
Abstract In this study, a semi-continuous culture mode was used for photo-hydrogen production by Rhodopseudomonas sp. nov. strain A7 and 3 key operating parameters (the interval feeding time, initial feeding time and the feeding volume ratio) were optimized to improve hydrogen production performance.

Bread wastes to energy: Sequential lactic and photo-fermentation for hydrogen production

International Journal of Hydrogen Energy, 2018
Abstract One third of the World's entire food production is lost or wasted every year. Biohydrogen production offers a possibility to re-use this resource; in particular, bread and bakery products wastes, due to their composition (up to 70% of carbohydrates, mostly starch), represent an appropriate source of nutrients for microorganisms.
