  Background and Objective: Aquatic hyphomycetes, which abundantly occur in submerged leaf litter are also reported as endophytes of riparian plant roots. This study was aimed to evaluate two aquatic hyphomycetes Campylospora parvula Kuzuha and Tetracladium setigerum (Grove) Ingold recovered from the living roots of Pilea scripta and Barberries vulgaris, respectively as endophytes for their role as plant growth promoter. Materials and Methods: A pot experiments was conducted in controlled glass house conditions. The used endophytic fungi were found very effective to enhance the growth of Chilli plant (Red pepper). The effect of these endophytes were measured for shoot and root lengths, shoot and root diameters and thereafter, total fresh mass and total dry mass, number of leaves of test plants and compared with control pot plants. Results: Both the aquatic hyphomycetes were found potent plant growth promoter in all parameters (p<0.005, significant). The effect of T. setigerum and C. parvula against control plants were found remarkable as total dry biomass of test plants was enhanced by 94.2% and 89.9%, respectively. Conclusion: The present findings provide a pavement in the field of bio-prospection of root endophytic aquatic hyphomycetes, which may be a new alternative source of bio fertilizer in agriculture.

  Hexane, chloroform, methanol and water extracts of aerial part of a high altitude Himalayan medicinal plant Valeriana wallichii DC. (Valerianaceae) were tested for their in vitro antimicrobial properties against animal and plant pathogenic bacteria using disc diffusion method. Aqueous extract showed the highest activity against Staphylococcus aureus (23±1.0 mm zone of inhibition, MIC 250 and MBC 500 μg mL-1) followed by methanol extract against Bacillus subtilis (20±1.0 mm ZOI, MIC 31.25 μg mL-1 and MBC 500 μg mL-1), Staphyloccocus aureus (19±0.8 mm ZOI, MIC and MBC 125 μg mL-1) and hexane extract against Bacillus subtilis (18±1.2 mm ZOI, MIC and MBC 125 μg mL-1). Chloroform extract showed the least activity against the test bacteria. The inhibitory potential of V. wallichii extracts was found very notable as compared to Ampicillin (10 mcg) and Erythromycin (15 mcg) which were used as positive control against these tested microorganisms and therefore this plant can be used as a good source of antibiotic substances for possible treatment of bacterial infections of both plants and animals.
