Identification and Characterization of Antibiotic-producing Actinomycetes Isolates
Actinomycetes are a gram-positive, filamentous subgroup of bacteria most known for antibiotic production. In fact, most of the antibiotics available today have originated from actinomycetes, namely from the genus Streptomyces. Novel bacteria with antimicrobial activities have been discovered from bacterial screen studies for decades and there is still much more yet to be unearthed. One hundred ...
متن کاملPhylogenetics of an antibiotic producing Streptomyces strain isolated from soil
Traditional methods of species classification and identification of the organism are based on morphological, physiological, biochemical, developmental and nutritional characteristics. Accurate assignment of taxonomic status to the new biologically active microbial isolates through existing bioinformatics methods is now very essential and also helpful in chemical characterization of the active m...
متن کاملDiversity of Biosurfactant-producing Streptomyces Isolates from Hydrocarbon-contaminated Soil
Actinomycetes are unsurpassed as producers of bioactive metabolites, primarily those with antimicrobial/anticancer properties; however, their capacity for producing other natural products such as biosurfactants, has been less explored. Biosurfactants are heterogeneous surface active compounds and can be potentially deployed for bioremediation of hydrocarbons and as emulsifying agents in agricul...
متن کاملSelection of Biosurfactan/Bioemulsifier-Producing Bacteria From Hydrocarbon-Contaminated Soil
Petroleum-derived hydrocarbons are among the most persistent soil contaminants, and some hydrocarbon-degrading microorganisms can produce biosurfactants to increase bioavailability and degradation. The aim of this work was to identify biosurfactant-producing bacterial strains isolated from hydrocarbon-contaminated sites, and to evaluate their biosurfactant properties. The drop-collapse method a...
متن کاملEvaluation of Antibiotic Resistance Patterns and Frequency of Carbapenemase-Producing Acinetobacter baumannii Isolates by the Carbacineto NP Test
ABSTRACT Background and Objectives: Acinetobacter baumannii is an opportunistic pathogen associated with nosocomial infections. Treatment of infections caused by this bacterium has become challenging due to increasing rate of resistance to a wide range of antibiotics such as carbapenems. One of the main mechanisms of resistance to carbapen...
