Herbal waste of processed medicinal plants of a local pharmaceutical industry was pretreated by steam explosion (160C for 0.5 – 2.0 h), and the process was accelerated by the use of Conc. H2SO4 (0.5 – 2.0%, 160 C for 0.5 – 2.0 h), NaOH (0.5 – 2.0%, 160C for 0.5 – 2.0 h). Significant increase in the content of reducing sugars was found after acid/alkali pretreatment of steam exploded herbal biom...

The oleaginous yeast Yarrowia lipolytica is an industrially important host for production of organic acids, oleochemicals, lipids, and proteins with broad biotechnological applications. Albeit known for decades, the unique native metabolism of Y. lipolytica for using complex fermentable sugars, which are abundant in lignocellulosic biomass, is poorly understood. In this study, we activated and ...

Ethanol production from agro-based raw materials normally involves two major steps, fermentation and distillation. These steps are reviewed, mainly in relation to molasses, which is the most common raw material in tropical countries. The specific effect on fermentation efficiency of molasses quality in terms Fermentable Sugars, the ratio of fermentable to non-fermentable solids, Volatile Acids,...

Steam pretreatment is one of the most efficient pretreatment technologies employed prior to enzymatic hydrolysis of lignocellulosics to obtain high polysaccharide conversion. In this study, steam pretreatment of non-impregnated hemp hurds was investigated at two reactor scales (2 and 10 L) by varying the temperature from 200–230 °C. Glucan recoveries were relatively high (> 82 % of original con...
