In order to find new actinomycete resources for discovering new drug leads, the actinomycete associated with lichens was studied. Three species of lichen samples were collected from 3 locations of Yunnan. Actinomycetes in the samples were isolated with 11 media, and identified with 16S rRNA gene sequence procedures. Bacteria of two of the three species were sequenced by using 454 pyrosequencing...
Endophytic actinomycetes have shown unique plant growth promoting as well as antagonistic activity against fungal phytopathogens. In the present study forty-two endophytic actinomycetes recovered from medicinal plants were evaluated for their antagonistic potential and plant growth-promoting abilities. Twenty-two isolates which showed the inhibitory activity against at least one pathogen were s...
UNLABELLED BACKGROUND Hypersaline solar salterns are extreme environments in many tropical and subtropical regions throughout the world. In India, there are several coastal solar salterns along with the coastal line of the Bay of Bengal and Arabian Sea and inland solar salterns around Sambhar saltlake, from which sodium chloride is obtained for human consumption and industrial needs. Studies...
rhizoctonia solani قارچی خاکزیست و برای بقای ساپروفیتی وگسترش خود در خاک توده های متراکم و سخت میسیلیومی تولید میکند. علی رغم تاثیر نسبی پاره ای از مواد شیمیایی در کنترل این بیماری به نظر میرسد کاربرد ترکیبات شیمیایی جهت مهار بیماری از نظر اقتصادی و زیست محیطی قابل توجیه نمی باشد. تصور میشود کنترل بیولوژیک یکی از روش های مناسب مبارزه با این بیماریست.
mesophilic bacteria, fungi and actinomycetes varied during composting cycles with high numbers in the initial and final cycles with maximal values in compost c and d, and sharply decreased in the heating cycles. staphylococcus aureus and bacillus subtilis were dominated at the initial composting cycle. whereas, at maturity bacillus subtilis was the major followed by b.badies, b.polymixa and b.b...

Marine sponge-associated actinomycetes are considered as promising sources for the discovery of novel biologically active compounds. In the present study, a total of 64 actinomycetes were isolated from 12 different marine sponge species that had been collected offshore the islands of Milos and Crete, Greece, eastern Mediterranean. The isolates were affiliated to 23 genera representing 8 differe...
2-Deoxy-scyllo-inosose (DOI) synthase is the enzyme participating in biosynthesis of 2-deoxystreptamine (DOS)-containing aminoglycoside antibiotics. The gene which encodes the enzyme can be a marker for screening of DOS-containing aminoglycoside-producer and exploration of its biosynthetic gene. Further, this enzyme is expected to be of use in industry, because it converts sugar into 6-membered...
The principle aim of this study was to isolate dye degrading actinomycetes from soil, mainly from agricultural farm lands and waste disposal areas, followed by characterization of the obtained isolates and to screen for dye degradation potential. Experiments included collection of soil samples; isolation of actinomycetes by serial dilution and spread plate technique on ISP2 medium, screening fo...
Xylanases are a group of depolymerizing enzymes often used for the hydrolysis of xylan (present in hemicellulose) to monomeric sugars and comprise endo-xylanases (EC 3.2.1.8) and beta-xylosidases (EC 3.2.1.37). They often act in synergy with other enzymes for complete hydrolysis of hemicellulose. Xylanases find several industrial applications, for example in food and feed industries, paper and ...
