Abstract |
: |
Twenty one fungal species belonging to ten genera were
isolated from the litter of eight dominant plants cover of Al-Taif
province, Saudi Arabia. The most frequently isolated fungal species
were Fusarium oxysporum (100%), Aspergillus alutaceus, A. niger,
and Macrophomina phaseolina (87.5%), F. solani, Mucor racemosus,
Penicillium glaburum (75%), and P. jaczewskii (62.5%). The influence
of temperature and pH on selected eleven isolates, representing
the dominant fungal species, was estimated. The representative
moulds failed to grow at 55ºC temperature. A flavipes, A. niger and
Emericella nidulans showed thermotolerant activity (optimum growth
at 35ºC). The selected fungal species responded differently to the
tested pH values of Czapek-Dox medium; some appeared to be acidophilic
(P. jaczewskii, T. harzianum, F. niveus, A. flavipes and A.
melleus, pH 3.5-4.5), some alkaliphilic (Emericella nidulans and
Gliocladium roseum, pH 8.1) and a third group attained their best
growth values around neutral pH (5.9-6.8). The selected moulds were
capable of producing cellulytic, pectinolytic and amylolytic enzymes,
which indicate their major role in litter decomposition |
