There is an increasing interest in improving biological processes, including fermentation conditions difficult, as it requires the use of appropriate improvement method that allows operating fermenter under optimal order to obtain largest possible amount final product. The aim this work was succeed examples produce quantity dry yeast biomass Saccharomyces cerevisiae using grape juice sole carbo...

In this study, we employed microwave-acid pretreatment for water hyacinth (WH) to obtain liquid hydrolysate that contains sugars derived from holocellulosic components of biomass further oleaginous yeast fermentation. order remove the inhibitors such as furans after acid treatment, detoxification was done and compared efficiency step with non-detoxified towards capability Rhodosporidium toruloi...

Mangrove sediments host rich assemblages of microorganisms, predominantly mixed bacterial cultures, which can be efficiently used for biohydrogen production through anaerobic dark fermentation. The influence of process parameters such as effect of initial glucose concentration, initial medium pH, and trace metal (Fe(2+)) concentration was investigated in this study. A maximum hydrogen yield of ...

Studies on Simultaneous Saccharification and Fermentation (SSF) of corn flour, a major agricultural product as the substrate using starch digesting glucoamylase enzyme derived from Aspergillus niger and non starch digesting and sugar fermenting Saccharomyces cerevisiae in a batch fermentation. Experiments based on Central Composite Design (CCD) were conducted to study the effect of substrate co...

Gellan gum production was carried out by Sphingomonas paucimobilis ATCC 31461 in a simplified medium with a short incubation time, and a kinetic model for understanding, controlling, and optimizing the fermentation process was proposed. The results revealed that glucose was the best carbon source and that the optimal concentration was 30 g liter(-1). As for the fermenting parameters, considerab...
