In this study, a total of twenty four phosphate solubilizing bacterial (PSB) colonies were isolated on the Pikovskaya’s agar medium from different effluent exposed sediment of river Ganga. The bacteria showing clear halo zones around their colonies were considered as phosphate solubilizers. Out of 24 phosphate solubilizing bacterial isolates, 4 potential isolates showing highest halo zone on Pi...

BACKGROUND L-asparaginase has been used as a chemotherapeutic agent in treatment of lymphoblastic leukemia. In the present investigation, Bacillus sp. PG03 and Bacillus sp. PG04 were studied. METHODS L- asparaginases were produced using different culture media and were purified using ion exchange chromatography. RESULTS Maximum productivity was obtained when asparagine was used as the nitro...

This study provides new insights into the dynamics of bacterial community structure during phytoremediation. The communities of cultivable autochthonous endophytic bacteria in ryegrass exposed to polycyclic aromatic hydrocarbons (PAHs) were investigated with regard to their potential to biodegrade PAHs. Bacterial counts and 16S rRNA gene sequence were used in the microbiological evaluation. A t...

Takahashi, I. (McMaster University, Hamilton, Ontario, Canada). Localization of spore markers on the chromosome of Bacillus subtilis. J. Bacteriol. 89:1065-1067. 1965.-Attempts were made to locate spore markers on the chromosome by determining the mapping distance of ery(r), str(r), phe, tyr, and ser markers to which the spore markers are closely linked. The results obtained indicated that locu...

BACKGROUND To expand on the range of products which can be obtained from lignocellulosic biomass, the lignin component should be utilized as feedstock for value-added chemicals such as substituted aromatics, instead of being incinerated for heat and energy. Enzymes could provide an effective means for lignin depolymerization into products of interest. In this study, soil bacteria were isolated ...

The diversity of some of the culturable microorganisms associated with marine flora and fauna collected off Vizhinjam and Mulloor coast of South India was evaluated and their bioactive production potential determined. From a total of 24 bacteria, 4 actinomycetes and 8 fungi isolated from diverse marine sources, five bacterial species-BLM3, BSP2, BCS1, BCS4 and BMA6 showed inhibitory activity ag...

Microbiological food safety is a global issue therefore this study was designed to investigate the bacteria contamination in Wara (curdled milk) and antibiotic susceptibility of the bacterial isolates. A total number of twenty-seven samples of “Wara” were purchased from five different locations in Oyo South Senatorial District, Nigeria. The behavioural pattern was investigated using questionnai...

The aim of the present study is to investigate the electrochemical behaviour of orthodontic wires in artificial saliva with and without bacteria. Four factors were considered to characterize the bacteria present in the saliva, viz. urban and rural groups of vegetarians and non-vegetarians. The results showed that among the heterotrophic bacterial isolates, Gram-positive species dominated over t...

One alternative to increase production is maximize the use of biofloc system cultivation technology. However, problems in are; difficulty cultivators replace or alternatively commercial bacteria production. efforts made bacillus sp. The aim study was determine optimal concentration sp that could growth saline tilapia. This used a completely randomized design (CRD) with four treatments, each rep...
