Removal of heavy metals from wastewater needs advance chemical technology and is more expensive too. The cheaper alternative for this is the bioremediation using heavy metals resistant microorganisms. In this study, 10 heavy metal resistant bacteria were isolated from oxidation ditch of wastewater treatment plant of Bagmati Area Sewerage Project. These include chromium resistant Staphylococcus ...

The antibacterial activities of five antibiotics, three brands of Ofloxacins (Obenasin, Floxavid and Drovid) and two brands of Ciprofloxacins (Uroxin and Siprosan), and five commonly used disinfectants (Lysol, Dettol, Purit, Roberts and Wex-cide) against Staphylococcus aureus, Escherichia coli, Proteus spp., Pseudomonas aeruginosa, Streptococcus spp. and Bacillus spp. were investigated. The gro...

OBJECTIVES Akacid plus is a new member of the polymeric guanidine family of disinfectants. It was especially developed to enhance the antimicrobial activity of this class with significantly less toxicity. The in vitro activity of Akacid plus compared with chlorhexidine digluconate and mupirocin was tested against a total of 369 recent clinical isolates. METHODS The organisms tested by CLSI re...

The objective of this study is to provide fundamental data related to size-based characteristics of bioaerosol distributed in the general hospital. Measurement sites are main lobby, ICU, surgical ward and biomedical laboratory and total five times were sampled with six-stage cascade impactor. Mean concentrations of airborne bacteria and fungi were the highest in main lobby as followed by an ord...

      Random samples from asymptomatic leaves and branches of five native medicinal plants: Stachys lavandulifolia, Rumex pulcher, Hypericum scabrum, Starja bachteriarica and Achillea kellalensis were collected from Chaharmahal province of Iran and examined for the presence of endophytic bacteria and fungi with biological activity. From 8 isolated endophytic ...

To formulate an efficient and eco-friendly strategy for the management of cotton seedling disease complex, pot experiments were conducted and the efficiency of eight Bacillus strains against seven fungi involved in the disease were determined. A greenhouse evaluation of the interaction between fungal isolates and Bacillus strains was carried out. The evaluation revealed a very highly significan...

In Gram negative Escherichia coli there are two well-characterised primosomal assembly processes, the PriA- and DnaA-mediated cascades. The presence of PriA and DnaA proteins in Gram positive Bacillus spp. supports the assumption that both the PriA- and DnaA-mediated primosomal assembly cascades also operate in these organisms. However, the lack of sequence homology between the rest of the prim...

From April to August of 2000, Bacillus spp. were detected in the blood culture of 29 patients in a hospital in Japan. Of these patients, 19 had clinical signs of septicemia; positive culture in the remaining 10 patients was attributed to contamination with skin flora at the site of puncture. Of the 18 strains evaluated, 15 were Bacillus cereus, 2 were Bacillus subtilis, and one was Bacillus lic...

The results of a study on the microbiological stability of canned tuna produced by Italian companies and similar canned products manufactured in countries outside Europe are reported herein. The study involved 38 samples of canned tuna of various brands, of which 14 were produced by companies outside Europe and 24 by Italian companies. Qualitative and quantitative microbiological tests were con...
