TL;DR: Little is known about the role of cellulolytic enzymes in the biocontrol of plant pathogenic Oomycetes, which contain cellulose as the main cell wall component.
Abstract: Imperfect fungi in the genusTrichoderma are among the most promising biocontrol agents against a wide range of plant pathogenic fungi[1,2] Their biological control activity involves, among other mechanisms proposed, mycoparasitism, which can be accomplished through the production of lytic enzymes: chitinases, together with βglucanases and proteases, are considered to be the most critical in mycoparasitism[2,3]Correlation between the production of chitinolytic enzymes and the biocontrol of fungi containing chitin as the main cell wall constituent has been demonstrated for many Trichoderma species [4,9]. On the contrary, little is known about the role of cellulolytic enzymes in the biocontrol of plant pathogenic Oomycetes, which contain cellulose as the main cell wall component [10].

TL;DR: In this paper, a microbial preparation for processing industrial fermentation wastewater is described. The microbial preparation contains multiple microbes having excellent ability of degrading non-biodegradable pollutants, through reasonable compatibility between various strains, the microbial preparation has a good degradating effect and has a wide application prospect.
Abstract: The invention relates to a microbial preparation for processing industrial fermentation wastewater. The microbial preparation is prepared by mixing nitrosobacterium, Trichoderma longibrachiatum Rifai, aerobic denitrifying bacterium, acinetobacter baumannii, aspergillus niger, alcaligenes faecalis, Streptomyces lateritius, Candida albicans, Paenibacillus polymyxa and an adsorbent carrier. The microbial preparation contains multiple microbes having excellent ability of degrading non-biodegradable pollutants. Through reasonable compatibility between various strains, the microbial preparation has a good degradating effect and has a wide application prospect.

TL;DR: The presence of α-glucosidase in Trichoderma longibrachiatum is revealed which could serve as alternative species for the production of α -glucOSidase enzyme.
Abstract: The use of hydrolase enzyme plays an important role in the industrial
production of α-D-glucose from carbohydrate sources. This study
investigated partial purification and characterization of
α-glucosidase from Trichoderma longibrachiatum with a view to
enhancing its potentials in biotechnological processes. Strains of
Trichoderma longibrachiatum were cultured on rice bran medium at
30°C for 96 hour for the production of a¯glucosidase. The
enzyme was partially purified by eluting the ammonium sulphate (70%)
saturation precipitated sample on Sephadex G-75 and Sephadex G-25.
Enzyme assay was carried out using
p-nitrophenyl-α-D-glucopyranoside (PNP- α-G) as the substrate
and protein concentration was determined. Kinetic parameters, molecular
weight, pH effect, temperature and thermostability were also
determined. The activity of enzyme in the presence of arylglucosides
and different cations were monitored. The partially purified protein
migrated as a single band in 10% SDS-Polyacrylamide
gel-electrophoresis. The enzyme presented a relative molecular weight
of about 58KDa as estimated by PAGE. The extracellular
α-glucosidase showed typical α-glucosidase activity,
hydrolyzing p-nitrophenyl-α-D-glucopyranoside and exhibited
optimum catalytic activity (4.89µmol/ml/min) at 40°C and pH
4.5. The enzyme was stable at 40°C for 150 minutes.
Carboxymethylcellulose was also hydrolyzed by this enzyme. The Km and
Vmax with p-nitrophenyl- α -D-glucopyranoside were 33.33mM and
20.00 µmol/min/mg protein respectively. This study therefore
revealed the presence of α-glucosidase in Trichoderma
longibrachiatum which could serve as alternative species for the
production of α-glucosidase enzyme.
