screening of microorganisms for the production of novel antibiotics has been intensivelypursued for many years by scientists. actinomycetes have the capability to synthesize manydifferent antibiotics. a total of 69 actinomycete isolates were recovered from soil samplescollected from alborz province. selected colonies (rough, chalky) of actinomycetes werepurified. all screened isolates were iden...

halophilic bacteria grow over a wide range of salt concentrations. in this study we aimed to isolate and screen out the halophilic bacteria and to determine their activity for production of the bioactive compounds. a total of 50 water, sediments and soil samples were collected from maharlu salt lake in southern region of fars-iran and subjected for isolation of the bioactive compound producing ...

Background: Agaricus bisporus is an edible basidiomycete fungus. Both the body and the mycelium contain compounds comprising a wide range of antimicrobial molecules, contributing in improvement of immunity and tumor-retardation. Objectives: The presence of endophytes capable of producing bioactive compounds was investigated in Agaricus bisporus. Materials and Methods: Endophytes from Agaricus b...

In order to identify the resulted bioactive strain MSB-6 from primary and secondary screening of marine soil samples, various morphological, physiological and biochemical tests are performed. Further confirmation is done by the 16S rRNA gene analysis. The reports confirmed strain MSB-6 as Pseudomonas fluorescens and it is deposited to Gene Bank with the accession number KC852045. It is mesophil...

The microbial source, variety of producing species, functions and an assortment of bioactivities of metabolites. The probable numbers of metabolites may be discovered in the future, the problems of dereplication of recently isolated compounds as well as the new trends and prediction of the research are also discussed. Ten isolates were isolated from different plant parts (root, stem, leaves) of...

conclusions the present study confirms the notion of selecting endophytic fungi of medicinal plant justicia for the bioassay-guided isolation of its bioactive compounds, and demonstrates that endophytic fungus chaetomium sp. nf15 could be a potential source of bioactive metabolites materials and methods endophytic fungi associated with the j. adhatoda l. plant were isolated from healthy plant p...

A total of 118 actinobacterial isolates were collected from the three types of termite nests (mound, carton, and subterranean nests) to evaluate their potential as a source of bioactive actinobacteria with antimicrobial activity. The highest number (67 isolates) and generic abundance (7 known genera) of actinobacterial isolates were obtained from carton nests. Streptomyces was the dominant genu...
