As conventional physico-chemical heavy-metal remediation technologies like ion-exchange, reverse osmosis, electrodialysis etc. are becoming extremely expensive, the possibility of use of microorganisms in bioremediation or biorecovery of different heavy metals from industrial effluents is extensively explored by different workers. Hexavalent chromium stressed environmental fungal isolates from ...

Pulp and paper mill effluent is posing a serious threat to the water and soil components of the environment due to its brown colour and high level of toxicity. Fungal treatment is one of the efficient methods for treating pulp and paper mill effluent. In the present study, for the treatment of from pulp and paper industry, nine efficient fungal strains including Phanerochaete chrysosporium, ded...

the root and flowers of butea monosperma (lam.) were extracted with methanol. extensive chromatographic separation and purification with the organic solvents was done. four phytochemicals were separated and their structures were established based on various spectroscopic techniques. isolated crude extract was subjected for antibacterial activity against gram-negative and gram-positive bacteria ...

india is one of the largest producers of onion in the world producing over 13,920,000 metric tons. storage is a major problem which leads to spoilage, and microbes play an important role in the spoilage. in this present study, biotechnologically important strains have been isolated from the spoiled onions by using appropriate enriched media. two potential strains were isolated and a brief compa...

BACKGROUND Herbal medicines have long been used for various ailments in various societies and natural bioactive compounds are gaining more and more importance due to various factors. In this context, three plant species i.e., Eryngium caeruleum, Notholirion thomsonianum and Allium consanguineum have been aimed for the scientific verification of their purported traditional uses against various i...

BACKGROUND Parrotiopsis jacquemontiana (Decne) Rehder. is locally used for skin infections and in wound healing. In this study we have evaluated methanol extract of its leaves and derived fractions against the clinical multi-drug resistant bacterial strains. METHODS P. jacquemontiana leaves powder extracted with 95% methanol (PJM) and fractionated in escalating polarity of solvents; n-hexane ...

PURPOSE The purpose of this study is to investigate the distribution and antimicrobial susceptibility of pathogenic bacteria in inpatients with pulmonary infection in the neurological intensive care unit (NICU). METHODS A total of 947 sputum specimens of 428 inpatients from May 2007 to May 2008 in the NICU were enrolled in the study, and bacterial identification and antibiotic susceptibility ...

The ascomycete Cryphonectria parasitica causes destructive chestnut blight, which is controllable by hypovirulence-conferring viruses infecting the fungus. tripartite chestnut/ C. /virus pathosystem involves dynamic interactions of their genetic elements, i.e., virus transmission and lateral transfer nuclear mitochondrial genomes between fungal strains via anastomosis occurring in trees.

Essential oils from herbs and roots of Conyza canadensis (horseweed), collected in Hungary, were obtained by hydrodistillation. The chemical compositions of the oils were analysed by combination of GC and GC/MS. The major constituent of the oil obtained from the aerial parts of horseweed was limonene (78%), while the main component of root oil was 2Z,8Z-matricaria ester. The antimicrobial activ...

Hexane, chloroform, ethyl acetate and methanol extracts of Azima tetracantha were screened for their antimicrobial activity against human pathogenic bacterial and fungal strains. Antimicrobial activity was carried out by disc diffusion method, determination of minimum inhibitory concentrations (MIC), minimum bacterial concentrations (MBC) and minimum fungicidal concentrations (MFC) against thre...
