THE PRODUCTION OF GLUCOAMYLASE BY ASPERGILLUS NIGER UNDER SOLID STATE CONDITIONS (RESEARCH NOTE)
In this study, Glucoamylase production by Aspergillus Niger was investigated under solid state conditions with low cost by-products of agricultural processes as substrate. Highest enzyme production was observed when a combination of wheat bran (WB) and corn flour (CF) was used as compared to WB+ rice bran, WB+ rice flour and WB alone. Different additions of (CF) were tested and WB+ 10% CF showe...
متن کاملXylanase Production under Solid State Fermentation by Aspergillus niger
Central composite orthogonal design was applied to quantify relations of xylanase production, loss of dry matter and change of pH with four critical variables during solid state fermentation of a mixture of wheat bran and wheat straw on which Aspergillus niger CCUG 33991 was cultivated. The studied variables included the percentage of wheat straw, temperature, moisture content, and fermentati...
متن کاملScanning Electron Microscopic Analysis of Aspergillus niger Pellets and Biofilms under Various Process Conditions
Aspergillus spp are among the powerful microbes involved in environmental management. The growth of Aspergillus niger varies in the form of pellets to biofilm. Pelleted form of growth has been observed in the media without any support, whereas growth nature has been shifted (pelleted to biofilm form) by incorporating solid support in the medium. Scanning electron microscopy (SEM) has proved to ...
متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Regulation of Pentose Catabolic Pathway Genes of Aspergillus niger
The aim of this study was to obtain a better understanding of the pentose catabolism in Aspergillus niger and the regulatory systems that affect it. To this end, we have cloned and characterised the genes encoding A. niger L-arabitol dehydrogenase (ladA) and xylitol dehydrogenase (xdhA), and compared the regulation of these genes to other genes of the pentose catabolic pathway. This demonstrate...
