TL;DR: In this article, a mesophilic bacterium Clostridium sp. YM1 was performed for the first time in the dark fermentation, and experimental results showed that the fermentative hydrogen was successfully produced by Clostrichium sp., with the highest cumulative hydrogen volume of 3821ml/L with a hydrogen yield of 1.7mH 2 /mol glucose consumed.

TL;DR: Palm kernel cake (PKC) was used for biobutanol production by Clostridium saccharoperbutylacetonicum N1-4 in acetone-butanol-ethanol (ABE) fermentation and linear effect of inoculums size with quadratic effect of pH and inoculum size influenced butanol production at 99% probability level.

TL;DR: The experimental data of scale up in 5 L bioreactor and flask scale were fitted to kinetic mathematical models published in the literature to estimate the kinetic parameters of the fermentation and the models used gave the best fit for butanol production, biomass and glucose consumption for both flask scale andBioreactor scale up.

TL;DR: In this article, the effect of various process parameters, including pH, incubation temperature, agitation speed and inoculums size on butanol production was studied, and it was shown that the highest butanol levels could be produced when the initial pH of culture medium, incubations temperature, and agitation speed were set at their optimum levels under the absence of crude palm oil.

TL;DR: Enzymatic experiments in optimum conditions revealed total fermentable sugars of 71.54±2.54g/L were produced and all factors studied had highly significant effects on total sugar liberated.
