Aspergillus parasiticus RCMB 002001 (2) producing four types of aflatoxins B1, B2, G1, and G2 was used in this study as an aflatoxin-producer. Penicillium griseofulvum, P. urticae, Paecilomyces lilacinus, Trichoderma viride, Candida utilis, Saccharomyces cerevisiae as well as a non-toxigenic strain of Aspergillus flavus were found to be able to exhibit growth on aflatoxin B1-containing medium u...

The effect of crop species and edaphic factors on the distribution of Trichoderma species in Alfisol soil under different agrosystems was evaluated. Each soil sample was assayed for nine abiotic factors and culturable microfungal populations. Fungal abundance was determined by dilution plate technique, and the identification of fungi was based on morphological characteristics. Pearson’s correla...

In order to compare the degradation of PLA composites by different microorganisms, and reveal mechanism. Actinomyces israelii, Aspergillus niger, Trichoderma harzianum Phanerochaete chrysosporium were selected degrade composites. The weight loss, functional groups, thermal properties crystallinity before after analyzed. results indicated that A. israelii niger had strongest ability composites, ...

The hydrolytic potential of cellulases produced by Trichoderma viride, Trichoderma pseudokoningii, Trichoderma koningii, and Trichoderma reesei with addition of exogenous β-glucosidase was evaluated on cellulose of steam-pretreated Lespedeza. The T. viride enzyme achieved the highest glucose conversion (90.09%), while T. pseudokoningii cellulase achieved the highest ratio of cellobiose to gluco...

An efficient heterologous protein production system was developed in Trichoderma viride, a very efficient cellulase producer. An expression vector containing the Taka-amylase A gene from Aspergillus oryzae, which was fused to the strong promoter and signal peptide sequence of the cellobiohydrolase 1 gene (cbh1) of T. viride, and the hygromycin B resistance gene was used to transform protoplasts...

The cultivation procedure and the fungal strain applied for enzyme production may influence levels and profile of the proteins produced. The proteomic analysis data presented here provide critical information to compare proteins secreted by Trichoderma reesei and Aspergillus niger when cultivated through submerged and sequential fermentation processes, using steam-explosion sugarcane bagasse as...
