Isolation of Gram-positive Bacteria from Different Sources and Evaluation of their Probiotic Properties
Introduction: Probiotics are defined as live non-pathogenic microorganisms and if administered in adequate amounts, can have beneficial effects on their hosts. This study aimed to isolate Gram-positive bacteria from different sources and to evaluate their probiotic properties. Methods: We obtained five samples from various sources including yogurt, infant feces, cheese, and soil under aseptic m...
متن کاملIsolation of anthracene resistant positive gram bacteria from Imam Khomeini Port oil polluted sediments
Today's most of microorganisms are used for purification of hazard waste such as municipal and industrial waste water and oil contaminants. In this study 2 bacterial species were isolated and purified in hydrocarbon (anthracene) containing media from oil polluted sediment of Imam Khomeini port. Bacillus pasteurii and Amphibacillus xylanus species were identified as indicator degrading bacteria ...
متن کاملA selective isolation procedure for Pseudomonas bacteria.
A selective isolation medium was devised for Pseudomonas bacteria. An antibiotic mixture which contained 10 micrograms per ml of cerexin A, 10 micrograms per ml of nalidixic acid and 30 micrograms per ml of cycloheximide was used. With the antibiotic medium, 58 strains of bacteria presumed to be Pseudomonas which were subdivided into 18 taxonomically different groups were isolated from 3 soil s...
متن کاملIsolation of Gram-negative Bacteria
Three different areas -hospital, food-handling establishments and human dwellings, were surveyed for pathogenic gram-negative bacteria carried on the cuticles of cockroaches. Fifty species of bacteria were identified from all cockroaches. Escherichia coli, Klebsiella pneumoniae, Citrobacter freundii and Enterobacter cloacae were the most frequently found. Pathogenic and potentially pathogenic b...
متن کاملBacteriocins of gram-positive bacteria.
In recent years, a group of antibacterial proteins produced by gram-positive bacteria have attracted great interest in their potential use as food preservatives and as antibacterial agents to combat certain infections due to gram-positive pathogenic bacteria. They are ribosomally synthesized peptides of 30 to less than 60 amino acids, with a narrow to wide antibacterial spectrum against gram-po...
