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...

An environmental actinomycetes, capable of utilizing p-nitrophenol as its sole carbon and nitrogen source, was starved for an 8-week period and showed no reduction in its ability to biodegrade p-nitrophenol. Microscopic examination revealed that starvation of the bacterium resulted in the fragmentation of filaments into individual cells.

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...

Although some seventy years have passed since the earliest descriptions of microaerophilic actinomycetes, there is still considerable debate concerning their identification and their classification. In all probability the final answer to these vexing problems will require the application of one or more serological procedures. It was with this in mind that the following studies were undertaken. ...

Actinomycetes are an important source of biologically active compounds, like antibiotics, antitumor agents, and immunosuppressors. Genome sequencing is revealing that this class of microorganisms has larger genomes relative to other bacteria and uses a considerable fraction of its coding capacity (5-10%) for the production of mostly cryptic secondary metabolites. To access actinomycetes biosynt...

A field experiment was carried out to study the changes of soil bacteria, fungi and actinomycetes in saline-sodic soils for different numbers of cultivated years under drip irrigation. The drip irrigation had substantial effects on levels of bacteria, fungi and actinomycetes. With increased number of cultivated years under drip irrigation, the soil biological properties were greatly improved. A...

To understand the effects of effective microorganisms (EMs) containing multiple strains on microbes and nutrients in kiwifruit planting soil, EMs prepared with four different strains were added to kiwifruit planting soil monthly from April to August. The counts of bacteria, fungi, actinomycetes, and total microbes were determined. The pH, total nitrogen (TN), alkali-hydrolyzable nitrogen (A-N),...
