The study aimed at determining the in vitro antimicrobial activity of alkaliphilic and halotolerant actinomycetes isolated from a mangrove ecosystem and identification of a potent strain. Twenty five isolates of actinomycetes were isolated from the sediment samples of Valapattanam mangrove swamp in Kerala, India. Antimicrobial activity of four selected actinomycete isolates was determined again...

In the era when large whole genome bacterial datasets are generated routinely, rapid and accurate molecular systematics is becoming increasingly important. However, 16S ribosomal RNA sequencing does not always offer sufficient resolution to discriminate between closely related genera. The SsgA-like proteins are developmental regulatory proteins in sporulating actinomycetes, whereby SsgB activel...

silver is composed of a large percentage of silver oxide due to their large ratio of surface to bulk silver atoms. silver nanoparticles have been a potent antibacterial, antifungal, anti-viral and anti-inflammatory agent. a simple, eco-friendly, inexpensive biosynthetic method was employed to synthesize silver nanoparticles.  the present study aimed at the comparative study of silver nanopartic...

The present study aimed to identify the effect of heavy metal concentration and soil pH on the abundance of the selected soil microorganisms within ArcelorMittal Poland steelworks, Cracow. The analysis included 20 soil samples, where the concentration of Fe, Zn, Cd, Pb, Ni, Cu, Mn, Cr and soil pH were evaluated together with the number of mesophilic bacteria, fungi, Actinomycetes and Azotobacte...

The removal of radionuclides, such as uranium (U) and thorium (Th) from aqueous solutions, especially from contaminated sources, seems to be a significantly useful subject for exploiting unused or abandoned energy resources. In this regard, efforts have been especially concentrated on studying the accumulation of U using microorganisms, such as the actinomycetes, bacteria, fungi, and yeasts. 14...

ABSTRACT: Actinomycetes are one of the important secondary metabolite producers. Researchers focused on exclusive marine areas for isolation and identification actinomycetes. The present study Nocardiopsis dassonovillei (ON627850) from TS Pettai region. potential strainTSP1 showed effective antibacterial activity against Haemophilus influenza. TSP1 isolates IC50 value 75.22 μg/ml antioxidant de...

Most hypogean environments particularly caves, are characterized by a stable temperature, usually in the range of 10±15 ± C, and high relative humidity. These ecosystems, when an allochthonous input of organic matter is present, seem to favor the growth of heterotrophic bacteria, from which actinomycetes predominate. Streptomyces species are particularly abundant and, in some cases, can be foun...
