The ability of microorganisms to degrade petroleum hydrocarbons is important for finding an environmentally-friendly method to restoring contaminated environmental matrices. Screening of hydrocarbon-utilizing and biosurfactant-producing abilities of organisms from an estuarine ecosystem in Nigeria, Africa, resulted in the isolation of five microbial strains identified as Corynebacterium sp. DDV...

OBJECTIVES To investigate the bacteria and fungi contaminating toys in neonatal intensive care unit (NICU) cots, the colonization rates, and factors that influence them. METHODS A cross-sectional, longitudinal bacteriologic survey of all toys in the cots of infants in an NICU. All the toys in an infant's cot were cultured weekly for 4 weeks. Data were collected on the infant's postnatal age, ...

Soil microbial communities play an important role in the biodegradation of different petroleum derivates, including hydrocarbons. Also other biological factors such as enzyme and respiration activities and microbial abundance are sensitive to contamination with petroleum derivates. The aim of this study was to evaluate the response of autochthonic microbial community and biological parameters (...

Macroalgae belonging to the genus Padina are known to produce antibacterial compounds that may inhibit growth of human- and animal pathogens. Hitherto, it was unclear whether this antibacterial activity is produced by the macroalga itself or by secondary metabolite producing epiphytic bacteria. Here we report antibacterial activities of epiphytic bacteria isolated from Padina pavonica (Peacocks...

The crude ethanolic extract and n-hexane, dichloromethane, ethyl acetate, n-butanol and aqueous fractions of Dodonaea viscosa were analyzed for antibacterial potential against four Gram positive bacteria: Bacillus subtilis, Bacillus cereus, Micrococcus luteus, Staphylococcus aureus, and three Gram negative bacteria: Escherichia coli, Salmonella typhi, Pseudomonas aeruginosa. Preliminary screeni...

Kocuria kristinae, previously called Micrococcus Kristinae was first described in 1974[1]. The organism is found widespread in nature, frequently as normal skin flora on humans and other mammals. It is usually non-pathogenic. There are very few documented cases with infections caused by Kocuria kristinae . Of these a majority occur in patients with indwelling devices, underlying diseases and su...

A rapid, simple lysostaphin lysis susceptibility test to differentiate the genera Staphylococcus and Micrococcus was evaluated. Of 181 strains from culture collections, 95 of 95 Staphylococcus strains were lysed, and 79 of 79 Micrococcus strains were not lysed. The seven Planococcus strains were resistant. Clinical isolates (890) were tested with lysostaphin and for the ability to produce acid ...

The present study was aimed to analyse the proximate composition and endophytic microbial colonization in six marine fishes such as Nemipterus japonicas, Epinephelus areolatus, Lutjanusquin quelineatus, Scolopsis bimaculatus, Lutjanus decussate and Lethrinus lensus, were collected from Mudasalodai coastal region, Tamil Nadu, South east coast of India. Maximum protein recorted Lethrinus lensus 4...

This study includes isolation, purification, and identification of algae from different environmental places (Tigris River and canal around AlJadriah) during February 2008. Nine unialgal cultures were obtainedwhich included 4 species of blue-green algae, 4 species of green algae, and 1 species of diatoms. However, contaminant bacteria and fungi were isolated from 4 of these algal cultures which...
