Biohydrogen production from synthesis gas (syngas) was investigated using a local bacterium isolated from anaerobic sludge of dairy wastewater. The isolated strain Rhodopseudomonas palustris PT was able to convert syngas to hydrogen through water shift gas (WGS) reaction. The aim of present study was to determine the optimum concentration of ferric citrate which avoids the cell growth inhibitio...

This study highlights biohydrogen production enrichment through NiO and CoO nanoparticles (NPs) inclusion to dark fermentation of rice mill wastewater using Clostridium beijerinckii DSM 791. (~26 nm) (~50 NPs were intrinsically prepared via facile hydrothermal method with polyhedral morphology high purity. Dosage dependency studies revealed the maximum characteristics for 1.5 mg/L concentration...

Biohydrogen is mainly produced by anaerobic bacteria, fungi, and algae under conditions. In higher eukaryotes, it thought that molecular hydrogen (H 2 ) functions as a signaling molecule for physiological processes such stress responses. Here, demonstrated white-rot fungi produce H during wood decay. The fungus Trametes versicolor produces from aerobic conditions, production completely suppress...

Hydrogen gas has tremendous potential as an environmentally acceptable energy carrier for vehicles, but most hydrogen is generated from nonrenewable fossil fuels such as natural gas. Here, we show that efficient and sustainable hydrogen production is possible from any type of biodegradable organic matter by electrohydrogenesis. In this process, protons and electrons released by exoelectrogenic ...

Biohydrogen production from microalgae is a potential alternative energy source that now intensively being researched. The complex natures of the biological processes involved have afflicted accuracy traditional modelling and optimization, besides costly. Accordingly, machine learning algorithms been employed to overcome setbacks, as these approaches capability predict nonlinear interactions ha...
