Analysis of the results studying dynamics microbiological indicators perishable food (fresh tomatoes), shows that control samples tomatoes without processing a preservative) on 15th day storage at 4±2 °C exceeds QMA&OAMO index, 5th yeast already detected. The activity yeasts and molds surface treated with Nisin is reduced compared control. It was found new isolated microorganisms synthesizi...

Two genes of the meta pathway of phenol degradation were cloned from a phenol-utilizing strain of Bacillus stearothermophilus and were mapped by subcloning and by use of a Tn5 insertion mutation. They code for phenol hydroxylase and catechol 2,3-dioxygenase, respectively. The gene encoding catechol 2,3-dioxygenase, which is more thermostable than catechol 2,3-dioxygenase encoded by the other ge...

Pseudomonas species are opportunistic pathogens with implications in a wide range of diseases including cystic fibrosis and sickle cell anaemia. Because of their status as multidrug resistant (MDR) and extremely drug resistant (XDR) bacteria Pseudomonas species represent a threat to public health. Prevalence, antibiogram and associated antibiotic resistant genes of Pseudomonas species isolated ...

To compare and assessment of Biodegradability Potential Pseudomonas putida Bacillus amyloliquefaciens on oil spill dispersant (Aquabreak Teepol) in Freshwater. Fresh water sample were collected from Biara, Gokana L.G.A, transported to the Microbiology Laboratory Rivers State University, Port Harcourt, Nigeria for analyses while Oil (OSD/Aquabreak) was purchased Barker Hughes, all state. Nine ex...

nas incognita have been previously described as being able to utilize citronellol, geraniol, and linalool (3, 6). Recently, a 50-megadalton (MDa) plasmid has been associated with the degradation of geraniol (9). In this report we describe the isolation of a Pseudomonas fluorescens s train capable of utilizing linalool as a sole carbon and energy source and demonstrate the presence of a transmis...

Fish is a very important component of human diet. A total 64 samples Clarias gariepinus were collected from two fish ponds each in Yaba, Ijegun, Ikorodu and Epe Lagos State, Nigeria. The bacterial flora the fishes determined quantitatively qualitatively. mean viable count ranged log10 7.6 cfu/g to 7.9 cfu/g. load on skin intestine generally higher than gills. Salmonella between 7.2 it was highe...

Ten bacterial strains that utilize cyanide (CN) as a nitrogen source were isolated from cassava factory wastewater after enrichment in a liquid media containing sodium cyanide (1 mM) and glucose (0.2% w/v). The strains could tolerate and grow in cyanide concentrations of up to 5 mM. Increased cyanide levels in the media caused an extension of lag phase in the bacterial growth indicating that th...

In the present study, we evaluated the antibacterial activity in the leaf extracts of Mentha piperita L. against pathogenic bacteria like Bacillus subtilis, Pseudomonas aureus, Pseudomonas aerogenosa, Serratia marcesens and Streptococcus aureus. The aqueous as well as organic extracts of the leaves were found to posses strong antibacterial activity against a range of pathogenic bacteria as reve...

The survival of selected hygienically relevant bacterial species in activated carbon (AC) filters on a bench scale was investigated. The results revealed that after inoculation of the test strains the previously sterilized AC absorbed all bacteria (10(6) to 10(7)). After a period of 6 to 13 days without countable bacteria in the effluent, the numbers of Escherichia coli, Pseudomonas aeruginosa,...
