Attack by bacterial viruses on members of the genus Actinomyces has been reported in only a few instances, but bacteriophages which attack Eumycetes are prevalent. Many industrial processes which employ bacteria are subject, to bacteriophage infestations. The isolation of bacteriophage from soil and sewage may be easily accomplished, but soil cannot be considered an abundant source of actinopha...

Actinobacteria are well known as secondary metabolites producers and hence of high pharmacological and commercial interest. In this study, soil samples were collected from Devathanam, a small town situated at the foothills of Western Ghats of Virudhunagar District, India and tests were performed to assess the presence of Actinomycetes and their morphology and biochemical activities. Nearly fift...

Microorganisms growing in saline environments represent an important source of biologically active compounds. Such environments are distributed all over the world and mainly include oceans, coastal and deep sea locations, soda lakes, soda deserts as well as artificial salterns. Many antibacterial, antifungal, anti-tumor, cytotoxic and photo protective compounds have been isolated till date from...

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...

Abstract Purpose Soil microorganisms play an indispensable role in the material and energy cycle of grassland ecosystems. The abundance these organisms vary according to environmental factors, such as time year soil depth. There have been few studies on transformation microbial communities degraded typical steppe temporal spatial changes. In this study, we analyze community structure diversity ...

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...

Periodontal diseases are very common among the people of all ages and also a proof of oral hygiene maintenance practice. A variety of microorganisms are found in human oral cavity which can often cause periodontitis, cavities, gingivitis, mineralization of tooth and other oral diseases. Current study was carried out to determine which microbes are responsible for dental carries among the patien...
