Hexavalent chromium reduction by metal resistant and halotolerant Planococcus maritimus VITP21

Halotolerant Cr (VI) reducing bacteria (VITP21) was isolated from kumta coastal region, India and was identified by biochemical methods and 16S rRNA analysis as Planococcus maritimus. The halotolerant bacteria exhibited complete reduction of 100 and 200 mg/L of Cr (VI) within 24 and 28 h, respectively and greater than 90% reduction was observed for higher concentration of Cr (VI) in the range of 300 to 500 mg/L (pH 7,...

Bacteria isolated from contact and non contact lens and antibiotic susceptibility patterns of isolated Pseudomonas aeruginosa

The aim of this study was to investigate the prevalence and type of microbial contamination, associated with contact lenses and lens care accessories used by a group of contact lens wearers. Results show that a total of 178 strains were isolated, including, 100 Gram positive and 78 Gram negative bacteria. Staphylococcus epidermidisand Pseudomonas aeruginosa were the most common microorganisms...

Analysis of culturable fungal diversity in rhizosphere soil of healthy and diseased cotton in Southern Xinjiang

The Southern Xinjiang is the main productive area of cotton, which is in long continuous cropping due to the limited land resources. The community structures of cultural fungiwere analyzed in the rhizosphere soil from healthy and diseased cotton fields. A total of236 soil fungal isolates were obtained by means of the soil plating and dilution plating method. Based on...

Laboratory evaluation of Beauveria bassiana (Bals.) Vuill. isolates to control the Callosobruchus maculatus (F.) (Coleoptera: Bruchidae) in cowpea grains

The cowpea weevil, Callosobruchus maculates is a pest which mainly attacks beans from the genus  Vigna, standing out as the most important bean weevil in the Brazil’s Northeast, where most of beans planted belongs to this genus. This work had as objective to evaluate the pathogenicity of different isolates of Beauveria bassiana to controlCallosobruchus maculatus in adult...

Isolation and molecular identification of antibiotic-producing actinomycetes from an old house in the medina of Fez, Morocco

Six actinomycetes strains were isolated from soil and deteriorated wood taken from an oldhouse in the medina of Fez, Morocco. The antimicrobial activity of these strains wastested against Gram-positive bacteria (Bacillus strains and Staphylococcus strains) andGram-negative bacteria (Pseudomonas strain and Escherichia strain)...

Novel complex organic substrates for cultivation of bacteria like Bacillus mojavensis A21

The media containing new complex organic substrates suggested that Mirabilis jalapatuber powder (MJTP), shrimp wastes powder (SWP) and sardinella peptone could be used as an alternative source of cheaper carbon and nitrogen substrates for production of enzymes by Bacillus mojavensis A21. The use of 40 g/L MJTP as a sole carbon and nitrogen sources resulted in a proteases and...

Detection of genus Salmonella and serogroups A, B, C1, D and (Vi) capsular producing strains using multiplex polymerase chain reaction (PCR) method from stool

In many countries, Salmonella is the leading cause of food-borne outbreaks and infections. A multiplex PCR (mPCR) for the detection of genus Salmonella and serogroups A, B, C1, D and capsular (Vi) producing strains from swabs of stool samples was developed. In the mPCR, primers for invasion (invA), O (prt, tyv, rfbj, wzxC1) and Viantigen genes (Vi) and internal amplification...

Misdiagnosis of tuberculosis: Sputum culture is a useful diagnostic tool in Quetta, Pakistan

Tuberculosis (TB) is a major contagious disease caused by Mycobacterium tuberculosisand is endemic in many countries of the world. It is estimated that worldwide one third human population are infected with TB. There is little use of sputum culture regarding diagnosis of tuberculosis in TB endemic areas. The undertaken study evaluated the importance of TB sputum culture than other diagnostic...

Identification of a new gene organization related to carbohydrate catabolism from Citrobacter sp. strain KCTC 18061P

A new gene organization related to carbohydrate metabolism of Citrobacter species has been identified on about 4.1 kb chromosomal DNA fragment. Sequence analysis revealed four open reading frames (ORFs), and gene orders were determined to be PTS system mannitol-specific transporter subunit EIICBA (MtlA), L-sorbose-1-phosphate reductase (SorE), class II fructose-1,6-biphosphatase (GlpX), and mannitol...
