Biofertilizers are an alternative to mineral fertilizers for increasing soil productivity and plant growth in sustainable agriculture. The objective of this study was to evaluate possible effects of three plant growth promoting rhizobacteria (PGPR) as biofertilizers on the growth of Cajanus cajan and Vigna radiata. The application treatments included the control (without bacterial inoculation) and plant growth promoting rhizobacteria (Rhizobium, Phosphobacterium, and Azotobacter) in sterilized soil. Data suggested that seed inoculation of Cajanus cajan and Vigna radiata with PGPR strains increased ischolar_main length, shoot length, leaf surface area and plant height when compared with control. Present results showed that PGPR strains stimulated plants growth and could be used as an alternative to chemical fertilizer.Keywords

60 pus samples collected from Coimbatore Medical College (CMC) were processed for the isolation of Candida albicans, among which 24 (40%) were found to be positive. Anticandidal susceptibility pattern revealed that the strains were highly sensitive to fluconazole, ketoconazole; moderately sensitive to clotrimazole and but resistant to nystatin. When the same strains were evaluated for their susceptibility towards aqueous and diethyl ether herbal extracts from Allium sativum, Punica granatum, Syzium aromaticum and Cassia auriculata the results were interesting that they are highly sensitive. The maximum inhibition was found to be 49 mm with Punica granatum followed by 29mm with Allium sativum. The GC-MS analysis of both the extracts revealed the bioactive principles responsible for anticandidal activity.Keywords

Thirty wheat samples procured from storage units in different zones of Coimbatore, Tamilnadu, India were processed to isolate the predominant fungal contaminants. Heterogeneous group of fungi were enumerated by standard plate count, among which four predominant organisms namely Aspergillus flavus, Aspergillus tamorii, Rhizopus spp. and Fusarium spp. were identified by macroscopic and microscopic observations. Since reputed journal reports, continuously highlight the impact of mycotoxin production in wheat by Aspergillus flavus, the isolate was chosen and processed to examine the production of aflatoxin and further analysis and confirmation was done using Albino rats and analytical techniques such as thin layer chromatography, immunodiffusion and Immunoelectrophoresis. TLC revealed the presence of G2 type of mycotoxin at a concentration of 15 ppb.Keywords
