Isolation and Screening of Cellulolytic Fungi
A large number of microorganisms are capable of degrading cellulose, only a few of these microorganisms produce significant quantities of enzymes capable of completely hydrolyzing cellulose. Fungi are the main cellulase producing microorganisms. In this purposed study, four fungal species belonging to two genera i.e. Trichoderma and Aspergillus were isolated from different sources, screened and...
متن کاملToxigenic thermophilic and thermotolerant fungi.
Twenty-three isolates of fungi, representing 13 thermophilic and thermotolerant species, were bioassayed for toxigenicity to brine shrimp, chicken embryos, and rats. Thirteen isolates representing nine genera were highly toxic to at least two of the three systems. Seven additional isolates of five genera were slightly toxic.
متن کاملThermophilic fungi: their physiology and enzymes.
Thermophilic fungi are a small assemblage in mycota that have a minimum temperature of growth at or above 20 degrees C and a maximum temperature of growth extending up to 60 to 62 degrees C. As the only representatives of eukaryotic organisms that can grow at temperatures above 45 degrees C, the thermophilic fungi are valuable experimental systems for investigations of mechanisms that allow gro...
متن کاملThermophilic Fungi to Dominate Aflatoxigenic/Mycotoxigenic Fungi on Food under Global Warming
Certain filamentous fungi produce mycotoxins that contaminate food. Mycotoxin contamination of crops is highly influenced by environmental conditions and is already affected by global warming, where there is a succession of mycotoxigenic fungi towards those that have higher optimal growth temperatures. Aflatoxigenic fungi are at the highest limit of temperature although predicted increases in t...
متن کاملSimple dye release assay for determining cellulolytic activity of fungi.
A colorimetric assay, based on the release of dye from a paper substrate, is described as a simple and rapid means of detecting cellulolytic activity. It is readily adaptable to rapidly screening in situ large numbers of fungal liquid cultures. Since it is a nondestructive assay, samples can be recovered for later use.
