Resumen
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

Resumen
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

Resumen
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

Resumen
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.

(The evaluation of nutritive value and In Vitro digestibility of oil palm fronds through fermentation by using Aspergillus niger with different soluble carbohydrate sources) ABSTRACT. Oil palm frond (OPF) is one of potential sources of alternative feed, but has limited use due to high crude fiber and low crude protein contents. Fermentation is one of the methods widely applied to improve nutritive value of animal feed. The purpose of this research is to increase nutritive value of fermented oil palm fronds by adding different soluble carbohydrate source into fermentation media. The results of

Resumen
Carbohydrate-binding modules (CBMs) are protein domains located within a carbohydrate-active enzyme, with a discrete fold that can be separated from the catalytic domain. Starch-binding domains (SBDs) are CBMs that are usually found at the C-terminus in many amylolytic enzymes. The SBD from Aspergillus niger B1 (CMI CC 324262) was cloned and expressed in Escherichia coli as an independent domain and the recombinant protein was purified on starch. The A. niger B1 SBD was found to be similar to SBD from A. kawachii, A. niger var. awamori and A. shirusami (95–96% identity) and was classified as a

Resumen
Putak is a local feed in west Timor, East Nusa Tenggara Province. It is obtained from soft core of palm tree which is called gebang tree (Corypha gebanga). Putak contains high carbohydrate and fiber but low in protein. As an effort to increase the ptotein level in putak a research was conducted by fermenting it with mixed-cultured of Trichoderma reesei and Aspergillus niger. A laboratorium experimental method was used and arranged factorially in Completely Randomized Design 3 x 4 x 3 namely three inoculant levels of T. reesei (T): 5,0; 7,5 and 10,0 % (w/w), and four levels of A. niger (A) 0,5;

Resumen
The present study aimed to produce gibberellic acid through fermentation using banana (Musa sapientum) peel waste as substrate. Banana peel, a domestic and industrial waste, constitutes a potential source of cheap fermentable substrate for the production of other value-added products. Fusarium moniliforme ATCC 10052 and Aspergillus niger CBS 513.88 were used as fermenting organisms. The substrate was dried, ground and its proximate composition determined. The powdered substrate was added to a modified CzapekDox broth (a semisynthetic medium), with Carboxyl methylcellulose (CMC) as control. The

Resumen
In modern protein–carbohydrate interactions, carbohydrate–aromatic contact with CH–π interactions are used. Currently, they are considered driving forces of this complexation. In these contacts, tryptophan, tyrosine, and histidine are preferred. In this study, we focus on primary prebiotic chemistry when only glycine, alanine, aspartic acid, and valine are available in polypeptides. In this situation, when the aromatic acids are not available, hydrogen-bonding aspartic acid must be used for monosaccharide complexation. It is shown here that (DAA)n polypeptides play important roles in primary “

Resumen
The fungus Aspergillus niger is an industrial producer of pectin-degrading enzymes. The recent solving of the genomic sequence of A. niger allowed an inventory of the entire genome of the fungus for potential carbohydrate-degrading enzymes. By applying bioinformatics tools, 12 new genes, putatively encoding family 28 glycoside hydrolases, were identified. Seven of the newly discovered genes form a new gene group, which we show to encode exoacting pectinolytic glycoside hydrolases. This group includes four exo-polygalacturonan hydrolases (PGAX, PGXA, PGXB and PGXC) and three putative exo-rhamno

Resumen
Sugarcane bagasse is a waste of sugar factories and one of its lignocellulosic materials is still of limited use. Sugarcane bagasse consists of three main components, namely cellulose, hemicellulose, and lignin. Sugarcane bagasse can be converted into bioethanol through a hydrolysis process (the process of converting carbohydrates into glucose) which consists of a liquefaction and saccharification process and followed by a fermentation process. The hydrolysis method is carried out enzymatically. This research used alpha amylase and gluco amylase enzymes with various types of yeast including Sa
