Bacterial exopolysaccharides – a perception Tập 47 Số 2 - Trang 103-117 - 2007
Anita Suresh Kumar, Kalpana Mody, Bhavanath Jha
AbstractMicrobial polysaccharides are multifunctional and can be divided into intracellular polysaccharides, structural polysaccharides and extracellular polysaccharides or exopolysaccharides (EPS). Extracellular polymeric substances (EPS), produced by both prokaryotes (eubacteria and archaebacteria) and eukaryotes (phytoplankton, fungi, and algae), have been of to...... hiện toàn bộ
Microbial siderophores: a mini review Tập 53 Số 4 - Trang 303-317 - 2013
Ratul Saha, Nabaneeta Saha, Robert Donofrio, Lorelle L. Bestervelt
AbstractIron is one of the major limiting factors and essential nutrients of microbial life. Since in nature it is not readily available in the preferred form, microorganisms produce small high affinity chelating molecules called siderophores for its acquisition. Microorganisms produce a wide variety of siderophores controlled at the molecul...... hiện toàn bộ
Biodegradation of gallotannins and ellagitannins Tập 46 Số 1 - Trang 68-84 - 2006
Ming-Shu Li, Kai Yao, Qiang He, Dongying Jia
AbstractNowadays, many researches have been made on gallotannin biodegradation and have gained great success in further utilization. Some of industrial applications of these findings are in the production of tannase, the biotransformation of tannic acid to gallic acid or pyrogallol and detannification of food and fodder. Although ellagitannins have the typical C–C ...... hiện toàn bộ
Microbial detoxification of mycotoxin deoxynivalenol Tập 44 Số 2 - Trang 147-156 - 2004
Andrea Völkl, Bernhard Vogler, Margit Schollenberger, Petr Karlovský
AbstractDeoxynivalenol (DON) is a trichothecene secondary metabolite produced by Fusarium species infecting cereal crops. As a mycotoxin, DON causes losses in livestock production and poses a health risk to humans consuming contaminated cereal products. DON also acts as a virulence factor, facilitating the colonization of host plants by <...... hiện toàn bộ
Mycotoxins – prevention and decontamination by yeasts Tập 55 Số 7 - Trang 805-818 - 2015
Walter P. Pfliegler, Tünde Pusztahelyi, István Pócsi
The application of yeasts has great potential in reducing the economic damage caused by toxigenic fungi in the agriculture. Some yeasts may act as biocontrol agents inhibiting the growth of filamentous fungi. These species may also gain importance in the preservation of agricultural products and in the reduction of their mycotoxin contamination, yet the extent of my...... hiện toàn bộ
Effects of pH on the comparative culturability of fungi and bacteria from acidic and less acidic forest soils Tập 37 Số 5 - Trang 335-343 - 1997
Carola Matthies, Hans‐Peter Erhard, Harold L. Drake
AbstractUnder aerobic conditions, the culturable microbial population of acidic forest soils was more tolerant to acidic cultivation conditions than was the culturable microbial population of less acidic soils. The number of culturable bacteria decreased sharply under acidic cultivation conditions, while the number of culturable fungi remained relatively constant o...... hiện toàn bộ
Biodegradation of kerosene by Aspergillus ochraceus NCIM‐1146 Tập 47 Số 5 - Trang 400-405 - 2007
Ganesh Dattatraya Saratale, Satish Kalme, Sanjyot Bhosale, Sanjay P. Govindwar
AbstractThe filamentous fungus Aspergillus ochraceus NCIM‐1146 was found to degrade kerosene, when previously grown mycelium (96 h) was incubated in the broth containing kerosene. Higher levels of NADPH‐DCIP reductase, aminopyrine N‐demethylase and kerosene biodegradation activities were found to be present after the growth in potato dext...... hiện toàn bộ
