Recent progress in the measurement of the bioconversion of dietary provitamin A carotenoids to vitamin A is reviewed in this article. Methods to assess the bioavailability and bioconversion of provitamin Acarotenoids have advanced significantly in the past 10 y, specifically through the use of stable isotopemethodology, which includes the use of labeled plant foods. The effects of the foodmatri...
Dilute acid (DA) and Sulfite Pretreatment to Overcome Recalcitrance of Lignocelluloses (SPORL) pretreatments were directly applied to wood chips of four poplar wood samples of different genotypes (hereafter referred to as poplars; Populus tremuloides Michx. ‘native aspen collection’; Populus deltoides Bartr. ex Marsh Populus nigra L. ‘NE222’ and ‘DN5’; P. nigra Populus maximowiczii A. Henry ‘NM...
The development of alternative energy technology is critically important because of the rising prices of crude oil, security issues regarding the oil supply, and environmental issues such as global warming and air pollution. Bioconversion of biomass has significant advantages over other alternative energy strategies because biomass is the most abundant and also the most renewable biomaterial on...
For all industrial processes, modelling, optimisation and control are the keys to enhance productivity and ensure product quality. In the current study, the optimization of process parameters for improving the conversion of isoeugenol to vanillin by Psychrobacter sp. CSW4 was investigated by means of Taguchi approach and Box-Behnken statistical design under resting cell conditions. Taguchi desi...
Lignocellulosic biomass, which contains cellulose (40-50%), hemicellulose (25-50%) and lignin (10-40%), is the most abundantly available raw material on Earth [1]. Broadly, it is classified into three categories: virgin biomass, waste biomass and energy crops. Owing to the rapid growth of global population and corresponding agricultural activities, the amount of lignocellulosic waste biomass is...
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 ...
Optimization of Arundo donax Saccharification by (Hemi)cellulolytic Enzymes from Pleurotus ostreatus
An enzymatic mixture of cellulases and xylanases was produced by Pleurotus ostreatus using microcrystalline cellulose as inducer, partially characterized and tested in the statistical analysis of Arundo donax bioconversion. The Plackett-Burman screening design was applied to identify the most significant parameters for the enzymatic hydrolysis of pretreated A. donax. As the most significant inf...
Soybean extract residue (scum), a waste of soybean oil production, was examined as a raw material for C17-ketosteroid production. As a model process, its bioconversion to 9α-hydroxyandrost4-ene-3,17-dione (9-OH-AD) by Mycobacterium sp VKM Ac-1817D was studied. The content of transformable sterols (sitosterol, stigmasterol and campesterol) in scum was estimated at ∼14%. The bioconversion of scum...
Biodiesel can replace petroleum diesel as it is produced from animal fats and vegetable oils, and it produces about 10 % (w/w) glycerol, which is a promising new industrial microbial carbon, as a major by-product. One of the most potential applications of glycerol is its biotransformation to high value chemicals such as 1,3-propanediol (1,3-PD), dihydroxyacetone (DHA), succinic acid, etc., thro...
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...
