Genistein, an isoflavone, has been demonstrated to promote the health of human beings by reducing the incidence of specific chronic diseases, namely, cancer and atherosclerosis. The present investigation explores a novel method of extraction of genistein from soy source which consists of a bioconversion reaction using fermentation by microorganism namely Streptomyces roseolus NRRL B-5424. In si...

Liquid-state bioconversion (LSB) technique has great potential for application in bioremediation of sewage sludge. The purpose of this study is to determine the optimum level of LSB process of sewage sludge treatment by mixed fungal (Aspergillus niger and Penicillium corylophilum) inoculation in a pilot-scale bioreactor. The optimization of process factors was investigated using response surfac...

Attempting to correlate the characteristics of fractionated components from bamboo its susceptibility enzyme is often inconclusive depending on parameters pretreatment conditions. Based integrated analysis chemical components, cellulose bioconversion, characteristic property isolated hemicellulose, and lignin, optimal mild operation for Moso was 4% NaOH in 20% ethanol aqueous solution. A total ...

BACKGROUND Brewer's spent grain (BG), a by-product of the brewing process, is attracting increasing scientific interest as a low-cost feedstock for many biotechnological applications. BG in the present study is evaluated as a substrate for lignocellulolytic enzyme production and for the production of ethanol by the mesophilic fungus Fusarium oxysporum under submerged conditions, implementing a ...

Rapeseed meal is a cheap and abundant raw material, particularly rich in phenolic compounds of biotechnological interest. In this study, we developed a two-step bioconversion process of naturally occurring sinapic acid (4-hydroxy-3,5-dimethoxycinnamic acid) from rapeseed meal into canolol by combining the complementary potentialities of two filamentous fungi, the micromycete Aspergillus niger a...

Solid state fermentation (SSF) is a bioconversion process by microorganism and enzymes. It effectively depolymerizes the cellulose, ligno cellulose present in the agricultural produces, cereals and biomas. It also enriches protein, colour, antioxidant activity, modification of functional properties of cereals. Solid state fermentation provides wide range of application in food and bio processin...

−Aqueous two-phase system (ATPS) was applied for extraction bioconversion of xylan by xylanase from Trichoderma viride. Phase diagrams for poly (ethylene glycol) (PEG) and sodium citrate were determined at room temperature. The ATPS composed of 12.99% (w/w) PEG6000 and 12.09% (w/w) sodium citrate was favorable for partition of xylanase and used for extraction bioconversion of xylan. Batch hydro...

Artemisinin is a potential antimalarial drug effective against the multidrug resistant forms of Malarial Parasites. The current production of artemisinin is insufficient to meet the global demand. In the present study microbial biotransformation of arteannuin B, a biogenetic precursor of artemisinin to the later has been investigated. Screening studies carried out on several soil borne microorg...

The effectiveness of forest resources depends on the comprehensiveness and rationality their consumption processing into finished products. This article discusses problem using solid fir wood greenery residues generated during industrial production essential oils. Bioconversion is considered to be most promising use. objective this research was study chemical composition bioconversion products ...

The bioconversion of glycerol to 1,3-Propanediol by Klebsiella pneumoniae (K. pneumoniae) is a complex bioprocess. Because the transport mechanism of glycerol across cell membrane of K. pneumoniae was still not adequately understood, it is difficult to formulate reliable mathematical models. In this study, we aim to explore a novel model for describing the process of glycerol batch fermentation...
