Alder and conifer soil were examined for Streptomyces spp. and non-filamentous bacteria antagonistic to Phellinus weirii. Conifer soil supported higher populations Streptomyces spp. and higher percentage of Streptomyces species antagonistic to P. weirii than did alder soil. The populations of non-filamentous bacteria were low in both soils. Alder soil, however, had a higher percentage of non-fi...
the streptomycetes sp. scbt strain gen bank accession number eu143270 isolated from the rhizosphere soil of medicinal plants was collected from the kolli hills of tamil nadu, india. the strain streptomyces is designated as school of chemical and biotechnology (scbt), capable of inhibiting the growth of a wide range of gram-negative and gram-positive bacteria. an almost complete 16s rrna gene se...
Lactic acid bacteria (LAB) isolated from various foods are important due to their potential to inhibit microorganisms, including drug-resistant bacteria. The objectives of this investigation were to isolate and identify antibacterial substances producing LAB from Hentak, a traditional fermented fish product of Manipur (North-East India), and to optimize the production of antagonistic substances...
Objective: Probiotics are an important part of the microbiota associated with many diseases. The production food and supplements containing probiotic products has increased considerably in recent years, due to their protective effect on health antagonistic against some pathogenic microorganisms. However, it is unknown whether content these expected effect. In this study was aimed investigate &a...
conclusions it was found that the isolated bacteria produced biosurfactants that had a great potential for different industries. results the 3 isolates from cheese, yoghurt and silage were effective against isolated e.coli and could produce biosurfactants. phylogenic relationships of the 3 potential candidates were determined comparing the 16sr dna gene sequences, they were found to be as 3 iso...
The fungal community within dead wood has received considerable study, but far less attention has been paid to bacteria in the same habitat. Bacteria have long been known to inhabit decomposing wood, but much remains underexplored about their identity and ecology. Bacteria within the dead wood environment must interact with wood-decay fungi, but again, very little is known about the form this t...
abstract background and objective: lactic acid bacteria are gram-positive, catalase-negative, nonsporulating, either rod- or coccus-shaped bacteria that have beneficial effects on their hosts by producing antimicrobial substances such as lactic acid, hydrogen peroxide, bacteriocins and biosurfactants. bacteriocins are antimicrobial peptides that are produced by bacteria and can inhibit ...
The use of compounds produced by symbiotic bacteria against pathogens in animals is one of the most exciting discoveries in ecological immunology. The study of those antibiotic metabolites will enable an understanding of the defensive strategies against pathogenic infections. Here, we explore the role of bacteriocins explaining the antimicrobial properties of symbiotic bacteria isolated from th...
The emergence of bacterial pathogens resistant to all known antibiotics is a global health crisis. Adding to this problem is that major pharmaceutical companies have shifted away from antibiotic discovery due to low profitability. As a result, the pipeline of new antibiotics is essentially dry and many bacteria now resist the effects of most commonly used drugs. To address this global health co...
