Distribution of Cellulolytic-thermophilic fungi on various substrates and geographic locations in Pakistan

Eighty seven different strains belonging to seven different types of thermophilic-cellulolytic fungi such as aspergillus fumigatus,chaetomium thermophile var. dissitum,humicola grisea var. thermoidea,humicola insolens,sporotrichum thermophile,talaromyces duponti and torula thermophila were isolated from different habitats of sheikhupura,khanewal,sadiqabad and jacobabad. a. fumigatus showed 88-100% frequency of occurrence in all habitats,but other cultures showed different frequency of occurrence in different habitats ranging from 33-100%. results indicated that soil as habitat and sheikhupura as a locality are the rich source of such fungi in pakistan. diversity indices showed that complete diversity exists. however,100% diversity was not observed in any case. c. thermophile showed habitat specificity to soil and garden compost while h. insolens to textiles waste and herbivore,dung. among 87 isolates h. insolens tas-13 showed better cellulolytic potential.
