Description :
A cyanobacterium Calothrix javanica was isolated from the collected soil samples from different locations. Identification was carried out using morphological variation and taxonomical approaches according to Desikachary (1959) and Prescott (1962) .The axenic culture of Calothrix javanica was obtained by using the method recommended by Bolch and Blackburn (1996). The isolated species of Calothrix javanica was grown autotropically
in BG-11 medium as described by Rippka et al., (1979) and incubated at 30±2°c. After 25 days, biomass was harvested by filtration through double layered muslin cloth and dried using air blower. The biomass of this Calothrix javanica species was used for the assessment of antifungal activity against Aspergillus niger, Trichophyton capitanum, Aspergillus flavus, Fusarium Monelliforme, Helminthosphorium sp., Alternaria sp. and Candida albicans. In the light of the experimental result concerning the antifungal activity against the tested fungal organisms, the results recorded clearly showed that the methanol extracts of Calothrix javanica towards the tested fungi gave positive results.
