Phosphate solubilization by a few fungal strains belonging to the genera Aspergillus and Penicillium

Many phosphate solubilizing fungi (PSF) are found in soil and their introduction in the rhizosphere of crops not only increases the availability of phosphorus from insoluble sources of phosphate but also increases the efficiency of phosphate fertilizers such as superphosphate and rock phosphate. Studies on 2 strains belonging to Aspergillus niger, and 1 strain each of Aspergillus flavus, Penicillium aurantiogriseum and...

Identification of antagonistic bacteria for Amorphorallus konjac soft rot disease and optimization of its fermentation condition

Soft rot disease of Amorphorallus konjac, an important and potentially destructive corms disease, is caused by Pectobacterium species. Now, the conventional methods of controlling the disease include the breeding variety and the chemical control, but the effects are uncomfortable. The aim of this study was to screen antagonistic bacteria for soft rot disease and optimize its fermentation conditions. The antagonistic...

Evaluation of the potency of some entomopathogenic bacteria isolated from insect cadavers on Anopheles arabiensis Giles (Order: Dipthera; Family: Culicidae) mosquito larvae in Nigeria

The laboratory evaluation of larvicidal activities of some bacteria namely; Pseudomonas aeruginosa, Bacillus polymyxa and and Bacillus subtilis was assessed against the second and fourth instar of Anopheles arabiensis collected from South West Nigeria. Concentrations ranging from 1.3 x 107cfu/mL to 6.5 x 107 cfu/mL were tested on the larvae for a period of 48 h.  The disparity in the activities was monitored with...

Typing of Candida species isolated from blood cultures and analysis of their in vitro antifungal susceptibilities

The aim of the present study was to investigate antifungal susceptibility of Candida strains isolated from blood cultures in our tertiary hospital. Patients hospitalized between December 2008 and April 2011 whose more than one blood cultures revealed growth of Candida species and Candida strains isolated in these cultures were included in the study. In order to identify isolated yeast species, appearance and...

A monoclonal antibody-based antigen-capture enzyme-linked immunosorbent assay (ELISA) for the detection of bluetongue virus

A monoclonal antibody-based antigen-capture enzyme-linked immunosorbent assay (ELISA) was developed for the detection of bluetongue virus (BTV) in cell culture lysates and blood samples from sheep. The monoclonal antibody 3E2 and 1C11 specific to BTV VP7 were used as capture antibody and detection antibody, respectively. The assay has detected BTV 1-22 specifically, and had no cross-reactivity with the closely related...

The extraction on polysaccharide of sporocarp and static culture optimization conditions of Morchella esculenta from Qinghai-Tibetan Plateau

In this paper, adopting orthogonal design method, the Morchella esculenta mycelia from Qinghai-Tibetan plateau was preliminary studied in different growing conditions such as pH, temperature, carbon sources, nitrogen sources and growth factors. The results showed that the M. esculenta mycelium liquid fermentation pH was between 6.0 to 7.0, cultivating optimum temperature 24ËšC, training required for 1.2% of potassium...

Molecular characterization of Trichoderma longibrachiatum 21PP isolated from rhizospheric soil based on universal ITS primers

Trichoderma species are morphologically very similar and were considered for many years as a single species. A new strain Trichoderma longibrachiatum 21PP was isolated from a rhizospheric soil sample collected from Kaushambi district of an Indian State (Uttar Pradesh). The universal primers (ITS-1& ITS-4) were used for the amplification of 28S rRNA gene fragment that produced a sharp band of about 700 bp on the...
