This research explores the photofermentation of glycerol to hydrogen by Rhodopseudomonas palustris, with the objective to maximise hydrogen production. Two piecewise models are designed to simulate the entire growth phase of R. palustris; a challenge that few dynamic models can accomplish. The parameters in both models were tted by the present batch experiments through the solution of the under...

Biomass from energy crops and agroindustrial wastes can be biologically converted to liquid or gaseous fuels, such as ethanol, methanol, methane and hydrogen, which was recently characterized as the fuel of the future. Hydrogen is a clean and environmentally friendly fuel, which produces water instead of greenhouse gases when combusted. It can be produced by renewable raw materials, such as org...

Proof of principle of biohythane and potential energy production from garden waste (GW) is demonstrated in this study in a two-step process coupling dark fermentation and anaerobic digestion. The synergistic effect of using co-cultures of extreme thermophiles to intensify biohydrogen dark fermentation is demonstrated using xylose, cellobiose and GW. Co-culture of Caldicellulosiruptor saccharoly...

Effects of three selected variables viz. biomass concentration, initial chemical oxygen demand (COD) concentration and initial bicarbonate alkalinity (BA) on biological hydrogen production from palm oil mill effluent (POME) using the granulated sludge in batch culture were investigated. The experimental results were analyzed and modeled using a central composite design (CCD) of response surface...

The contents presented in this paper focuses on the performance of UASB (Upflow Anaerobic Sludge Blanket) reactor for treating various industrial and domestic wastewaters at various operating conditions. The reactors can be used conveniently for the treatment of tannery, distillery, food processing, metal mining, dairy, domestic wastewater etc. The performance of the reactor mainly depends on t...

Abstract Traditional wastewater treatment has been aimed solely at sanitation by removing contaminants, yet actual issues of climate change and depletion natural resources are calling for methods that both remove contaminants convert waste into chemicals fuels. In particular, biological treatments with synergic coupling microalgae bacteria appear promising to organic, inorganic, pathogen genera...
