Protease activity of actinomycetes isolated from various soil types of Georgia has been studied. Protease activity strains have been identified among mesophilic and extremophilic actinomycetes. Some strains of mesophilic, alkaliphilic and halophilic actinomycetes are characterized by alkaline protease activity. Their pH optimum for enzyme activity is 10-11. Strains of mesophilic actinomycetes: ...

Marine microorganisms widely distributed on our oceans of the earth and emerging as the great source for the discovery of natural products. Marine Actinomycetes are virtually unlimited sources of novel compounds with many therapeutic applications and hold a prominent position due to their diversity and proven ability to produce novel bioactive compounds. Actinomycetes represent a high proportio...

Actinomycetes (Actinobacteria) are highly attractive as cell factories or bioreactors for applications in industrial, agricultural, environmental, and pharmaceutical fields. Genome sequencing of several species of actinomycetes has paved the way for biochemical and structural analysis of important proteins and the production of such proteins as recombinants on a commercial scale. In this regard...

Over the recent years glutaminase free L-asparaginase has gained more importance due to better therapeutic properties for treatment of acute lymphoblastic leukemia. Actinomycetes are known for L-asparaginase activity. In the current study, 80 actinomycetes were isolated from various soil habitats by serial dilution technique. Presence of L-asparaginase was investigated in a total of 240 actinom...

This study was conducted under laboratory conditions to investigate the effects of herbicides (nicosulfuron, metribuzin and glyphosate) on the number of actinomycetes in soil and growth of several isolates of actinomycetes in vitro. The lowest tested concentrations equalled the recommended rates (1X), while the other three were five-fold (5X), ten-fold (10X) and fifty-fold (50X). Samples were c...

Actinomycetes-a group of antimicrobial producing bacteria-have been successfully cultured and characterized from the nest material of diverse arthropods. Some are symbionts that produce antimicrobial chemicals found to protect nest brood and resources from pathogenic microbes. Others have no known fitness relationship with their associated insects, but have been found to produce antimicrobials ...

A main objective of the present study was to isolate and identify the antibacterial activity of actinomycetes strains obtained from terrestrial habitat and to utilize the antibacterial production profitably for the eradication of pathogens which cause disease to human being. The actinomycetes strains were isolated from terrestrial soil sample of King Saud University, Riyadh, Kingdom of Saudi Ar...

هدف: سطوح بالای همیاری در جوامعی شکل می­ گیرد که آن افرادی از هنجارهای خاصی تخطی کنند، با رفتار تنبیهی دیگران مواجه شوند. هدف مطالعه حاضر تفکیک انواع واکنش افراد به پیشهادهای ناعادلانه و بررسی مولفه­ های الکتروفیزیولوژیک آنان بود. روش: 40 نفر جنسیت مذکر دانشجویان دانشگاه شهید بهشتی طریق نمونه گیری دسترس این شرکت کردند آنها اصلاح­ شده بازی ­های دیکتاتور اولتیماتوم مورد سنجش ارزیابی قرار گرفت. یا...

L Glutaminase, a therapeutic enzyme obtained from marine Actinomycetes gains importance because of their adaptability to varied environmental factors. An experimental study was carried out to isolate the L glutaminase producing actinomycetes from the marine sediment of Thoothukudi. Marine sediment sample was collected from six different locations of the Thoothukudi coastal ecosystem, enriched w...
