Knowledge of the chemical composition of both wild and cultivated edible mushrooms in Ghana is limited. This study reports their nutritional value, composition in lipophilic and hydrophilic molecules, minerals and antioxidant properties. The samples were found to be nutritionally rich in carbohydrates, ranging from 64.14 ± 0.93 g in Pleurotus ostreatus strain EM-1 to 80.17 ± 0.34 g in Lentinus ...

BACKGROUND Identifying new high-performance enzymes or enzyme complexes to enhance biomass degradation is the key for the development of cost-effective processes for ethanol production. Irpex lacteus is an efficient microorganism for wheat straw pretreatment, yielding easily hydrolysable products with high sugar content. Thus, this fungus was selected to investigate the enzymatic system involve...

Different conditions of culture medium, incubation time, concentration and surfactant were tested to determine xyloglucanase activity. Trichoderma viride, Paecilomyces farinosus, Wardomyces inflatus and Pleurotus ostreatus showed increased xyloglucanase activities when the fungi grown on microcrystalline cellulose as the sole carbon source. Endoxyloglucanase activity increased with the growth o...

The performance of the PLP, log-RASTA-PLP, and J-RASTA-PLP front ends for recognition of highly reverberant speech is measured and compared with the performance of humans and the performance of an experimental RASTA-like front end on reverberant speech, and with the performance of a PLP-based recognizer trained on reverberant speech. While humans are able to reliably recognize the reverberant t...

Transferring foreign genes into mushroom mediated by Agrobacterium tumefaciens is a standard technique in genetic engineering. Recombinant human insulin has been greatly used in the treatment of type I diabetes. The production of edible mushroom derived insulin should facilitate oral delivery. In this study we used the Agrobacterium tumefaciens mediated transformation method for the transfer an...

microorganisms are important components of soil. some soil filamentous fungi such aspenicilium produce many bioactive small molecules, or secondary metabolites, that range frombeneficial bioactive compounds to harmful toxins. in this study, the metabolites of threepenicillium species (p. goditanum, p. moldavicum and p. corylophilum) were extracted byadding ethyl acetate to liquid cultures. the ...
