Abstract:
For the purpose of finding a suitable available inducer in combination with starvation, carbohydrate mixtures from triticale was used as inducers and compared with well-known amylase inducers in fungi. Carbohydrate mixtures from triticale induced production of amylase cocktail (?-amylase and glucoamylase) in Aspergillus niger, unlike induction with well-known inducers which induce only glucoamylase, showed by zymogram and TLC analysis of carbohydrates mixtures before and after fermentations. Glucoamylase production by A. niger was highest in the presence of extract obtained after autohydrolysi

Abstract:
The conditions for biocatalytic cleavage of corn starch and rye whole grain flour for the subsequent cultivation of the Asperillus niger strain VKPM F-171 are described. As a result of this procedure, the amount of water-soluble carbohydrates in the substrates increased by 5-6 times in comparison with the initial raw material, and the content of glucan p-form in the hydrolysate of rye whole grain flour grew by 2-3 times. The content of glucans in the biomass by the end of the cultivation of A. niger VKPM F-171 on corn starch hydrolysate was 28±2% of dry matter, while the proportion of glucans

Abstract:
To extend the knowledge about the relationship between heat shock and oxidative stress in lower eukaryotes, the filamentous fungus Aspergillus niger 26 was chosen as a model system. Here, the response of A. niger cells to heat shock is reported. The temperature treatment significantly increased the levels of reactive oxygen species, superoxide anions (O2•–), and hydrogen peroxide and the rate of cyanide-resistant respiration as a marker of oxidative stress. Enhanced reactive oxygen species generation coincided with an increase in the content of oxidative damaged protein and in the accumulation

Abstract:
Background: Medium is a material consisting of a mixture of nutrients which functions as a place to grow microbes. Semi-synthetic media such as PDAs contain sufficient carbohydrates so that they are good for use for fungal growth. This medium is quite a lot needed in the breeding of Candida albicans and Aspergillus niger both in the laboratory. However, the price of this media is quite expensive and limited, while the need is increasing so that alternative media are needed to replace the breeding.
 Objective: To determine the growth rate of unicellular and multicellular fungi on breadfrui

Abstract:
Bacillus sp strain IBA 33 metabolites, isolated from decaying lemon fruits, were evaluated for the control of pathogenic and non-pathogenic fungi ( Penicillium digitatum, Geotrichum candidum, Penicillium expansum, Aspergillus clavatus, Aspergillus flavus, Aspergillus niger, and Fusarium moniliforme). These metabolites were recovered from Landy medium (LM) without aminoacids. In order to optimize metabolites production the LM was modified by adding different concentrations and sources of amino acids and carbohydrates at different culture conditions.

Abstract:
The contribution of microbial residues formed on lignin and cellulose to the formation of humus (HS) was investigated. The microbial residues formed by Aspergillus niger (A. niger) in the cultures of cellulose and lignin in a fluid medium were structurally characterized by elemental analysis, differential thermal analysis (DTA), FTIR spectroscopy and CP/MAS 13C NMR spectroscopy. Compared to cellulose itself, the microbial residue from cellulose contains more aromatic compounds and N-containing compounds and fewer carbohydrates and carboxylic compounds. A. niger improved the thermal stability a

Abstract:
In order to develop an effective and economical method for removing low concentration radioactive wastewater of uranium, the biomass of ‘CMCC(F)-98003’ Aspergillus niger was investigated in a batch system. The maximum uranium adsorption capacity of 12.5 mg g−1 was obtained at the initial uranium concentration of 0.75 mg L−1. The biosorption data on a biomass concentration of 0.029 g L−1 fitted well to the Freundlich isotherm with a correlation coefficient (R2) of 0.987. The calculated thermodynamic parameters showed that the biosorption of uranium ions was endothermic (ΔH° < 0). The res

Abstract:
Amylase is an indispensable and industrially important enzyme that hydrolyzes carbohydrates particularly starch into simple sugars. Amylase enzymes have been isolated from various sources such as microbes, animals and plants. However, microorganisms are highly preferred as compared to plants and animal sources. Amylases of fungal origin are highly stable compared to amylases produced by bacterial species. The aim of this study was to investigate the production of extracellular amylase enzyme from Aspergillus niger EFRL-FC-024 using sugarcane bagasse and corn waste as an energy source under sub
