Over the last decade, ochratoxin A (OTA) has been widely described and is ubiquitous in several agricultural products. Ochratoxins represent the second-most important mycotoxin group after aflatoxins. A total of 34 samples were surveyed from 3 locations, including Mecca, Madina, and Riyadh, Saudi Arabia, during 2012. Fungal contamination frequency was determined for surface-sterilized peanut se...

Aspergillus oryzae CCT 3940, Aspergillus awamori NRRL 3112 and a Trichoderma sp.) were compared for their capacity to produce endo-polygalacturonase (endo-PG) in solid state fermentation. Maximum pectinolytic activity was reached in 72 h of growth, the best two fungal strains being A. niger T0005007-2 and A. oryzae CCT 3940. Three types of commercial purified pectin and four of unprocessed pect...

Acipenser stellatus is one of the most invaluable species of Sturgeon fishes in the world. The purpose of this study was to identify the resident microbial community from the gastrointestinal tract (GIT) of Acipenser stellatus. One hundred and twenty three fungi were isolated from the GIT of 7 Acipenser stellatus samples including Aspergillus spp (45.5%), Trichoderma spp (8.9%) and Cladophialop...

The aim of the study was to assess the cellulolytic activity of a strain of Trichoderma viride in the presence of three lignocellulosic substrates, i.e. wheat, barley, and maize straw, in different temperatures (25 °C, 30 °C and 35 °C). Research related to the biosynthesis of enzymes was conducted using the deep method, whereas enzyme activity was assessed on solid media with added carboxymethy...

A mutant strain that secretes twice as much cellulase as its parent was obtained by irradiating conidia of Trichoderma viride QM 6a with a linear accelerator.

The comparative effectiveness of remediating water polluted with crude oil, using environment-friendly bacteria (Pseudomonas aeruginosa) and fungi (Aspergillus niger) were investigated. samples separately treated Aspergillus niger Pseudomonas aeruginosa. bioremediation kinetic efficiency for these systems was studied. At the end periods, oil grease content decreased from 47.0 mg/L in untreated ...

Nutrient supplementation could improve the biomethane production of different biomass feedstocks during anaerobic digestion. In this study, impact nutrient on digestion West African Gamba and Guinea Grass for is presented. This was undertaken in 6 separate continuous stirred tank reactors a hydraulic residence time 25 days under regime with trace elements (TE), cocoa pod (CP) ash-extract, comme...
