BACKGROUND Mycoparasitism, a lifestyle where one fungus is parasitic on another fungus, has special relevance when the prey is a plant pathogen, providing a strategy for biological control of pests for plant protection. Probably, the most studied biocontrol agents are species of the genus Hypocrea/Trichoderma. RESULTS Here we report an analysis of the(More)
The hypersecreting mutant Trichoderma reesei RUT-C30 (ATCC 56765) is one of the most widely used strains of filamentous fungi for the production of cellulolytic enzymes and recombinant proteins, and for academic research. The strain was obtained after three rounds of random mutagenesis of the wild-type QM6a in a screening program focused on high cellulase(More)
A PCR method suitable for the isolation of lipase genes directly from environmental DNA is described. The problems associated with the low levels of similarity between lipase genes were overcome by extensive analysis of conserved regions and careful primer design. Using this method, a lipase gene (oli-lipase) was isolated directly from environmental DNA.(More)
Glycosylation of proteins is important for protein stability, secretion, and localization. In this study, we have investigated the glycan synthesis pathways of 12 filamentous fungi including those of medical/agricultural/industrial importance for which genomes have been recently sequenced. We have adopted a systems biology approach to combine the results(More)
Coprophilous fungi inhabit herbivore feces, secreting enzymes to degrade the most recalcitrant parts of plant biomass that have resisted the digestive process. Consequently, the secretomes of coprophilous fungi have high potential to contain novel and efficient plant cell wall degrading enzymes of biotechnological interest. We have used one-dimensional and(More)
2-DE separations of protein extracts sometimes have problems with poor resolution and streaking. This problem is particularly apparent with microorganisms, most notably those with a large cell wall. Here we describe a novel, rapid protocol for the extraction of microorganisms in acidic conditions, leading to increased resolution and 2-D gel quality. The(More)
The filamentous fungus Paecilomyces lilacinus is currently developed as a biocontrol agent against plant parasitic nematodes. Nematode eggs and cuticles are the infection sites for biocontrol agents that penetrate by the production of lytic enzymes. P. lilacinus was cultured in liquid media and proteases and chitinases were induced by the introduction of(More)
Trichoderma atroviride has a natural ability to parasitise phytopathogenic fungi such as Rhizoctonia solani and Botrytis cinerea, therefore providing an environmentally sound alternative to chemical fungicides in the management of these pathogens. Two-dimensional electrophoresis was used to display cellular protein patterns of T. atroviride (T. harzianum(More)
Trichoderma harzianum is a soil-borne filamentous fungus that exhibits biological control properties. T. harzianum can prevent the growth of pathogenic fungi on many types of plant crops, providing a chemically benign alternative to fungicidal agents currently on the market. A proteomic approach was taken to separate and identify proteins from a strain of(More)
O-Linked glycosylation often occurs in mucin-type domains that are heavily and heterogeneously glycosylated and are challenging to analyze. The analysis of these domains is often overlooked because of these difficulties, but changes in mucinlike domain glycosylation are implicated in many diseases. Here we have explored several strategies to determine the(More)
