Production of extracellular endochitinase could be increased 5-fold in the mycoparasite fungus Trichoderma harzianum by using the cellulase promoter cbh1 of Trichoderma reesei, whereas the total endochitinase activity increased 10-fold. The cbh1 promoter was not expressed on glucose and sucrose in T. harzianum and was induced by sophorose and on cellulase-inducing medium. The endogenous endochi...
Optimal operating parameters of 2,3-Butanediol production using Klebsiella oxytoca under submerged culture conditions are determined by using Taguchi method. The effect of different factors including medium composition, pH, temperature, mixing intensity, and inoculum size on 2,3-butanediol production was analyzed using the Taguchi method in three levels. Based on these analyses the optimum conc...
Background and purpose: The genus Phlomis and Stachys (Labiatae) are widely distributed in Iran. There are no reports on the antimicrobial activity of some of these plants. The medicinal properties attributed to the genus Phlomis and Stachys prompted us to investigate the antimicrobial activity of the methanolic extracts of Phlomis bruguieri, P. herba-venti, P. olivieri, Stachys byzantina, S....
Volume 5, no. 13, e00137-17, 2017, https://doi.org/10.1128/genomeA.00137-17. Page 2: The Acknowledgments should include the following. “We thank Christian Kubicek, Irina Druzhinina, and Igor Grigoriev for providing access to unpublished genome data produced by the U.S. Department of Energy Joint Genome Institute, a DOE Office of Science User Facility, supported by the Office of Science of the U...
Background: Today, with the development of human life and the overwhelming fall of antibiotics and uncontrolled bacterial resistance, the need to find materials with antimicrobial effects is felt more than ever. Nanotechnology has created a new opportunity to investigate the antimicrobial effects of nanomaterials. Materials & Methods: In this study, using hydrothermal and microwave auxiliary c...
The phylogenetically most derived group of the genus Trichoderma - section Longibrachiatum, includes some of the most intensively studied species, such as the industrial cellulase producer T. reesei (teleomorph Hypocrea jecorina), or the facultative opportunistic human pathogens T. longibrachiatum and H. orientalis. At the same time, the phylogeny of this clade is only poorly understood. Here w...
سبوس گندم با دارا بودن فیبر و املاح بالا از خواص تغذیهای سودمندی برخوردار است، اما بهدلیل حضور ترکیب ضد تغذیهای بهنام اسید فیتیک کاربرد محدودی دارد. در این پژوهش اثر سه آغازگر مختلف تهیه شده از S. cerevisiae PTCC 5052 و L. Plantarum PTCC 1058، درجه حرارت (25، 30 و 35 درجه سانتیگراد) و طول زمان تخمیر (0،2، 4، 6 و 8 ساعت) بر مقدار pH ، اسیدیته و غلظت اسید فیتیک سبوس گندم استریل شده بررسی گر...
Morphological and molecular identification of Trichoderma isolates on North American mushroom farms.
Green mold disease (causal agent, Trichoderma) has resulted in severe crop losses on mushroom farms worldwide in recent years. We analyzed 160 isolates of Trichoderma from mushroom farms for morphological, cultural, and molecular characteristics and classified these isolates into phenotypic groups. The most common group comprised approximately 40% of the isolates and was identified as a strain ...
A comparative study of the secondary metabolism of two Trichoderma spp. with that of the Thctf1 transcription factor gene null mutant of Trichoderma harzianum 34 was carried out in order to deepen our knowledge of the biosynthetic pathway and mode of action of 6-pentyl-2H-pyran-2-one (1) and its derivatives as biocontrol agents. New isolated metabolites have shed light on the detoxification mec...
In this study Trichoderma atroviride was selected as over producer of chitinase enzyme among 30 different isolates of Trichoderma sp. on the basis of chitinase specific activity. From this isolate the genomic and cDNA clones encoding chit33 have been isolated and sequenced. Comparison of genomic and cDNA sequences for defining gene structure indicates that this gene contains three short introns...
