ABSTRACT	Fifteen species of thermophilic and four species of thermotolerant fungi were isolated from soil samples collected at various localities in Taiwan. Fourteen species and three strains responded to three h of thermal stress at elevated temperature from 30°C to 50°C by synthesizing 30 heat shock proteins (HSPs) with molecular weights ranging between 20-150 kDa. Heat shock treatments at 40°C, resulted in the synthesis of 22 HSPs with molecular weights of 30-150 kDa. Nine of the seventeen fungal species produced a 46 kDa HSP, seven species a 52 kDa HSP, and five species a 94 kDa HSP. Four of the seventeen species produced two kinds of HSPs with molecular weights of 87 kDa and 40 kDa. Ten fungal strains responded to an elevated temperature of 50°C and synthesized 12 HSPs of molecular weights ranging from 20 to 92 kDa. Six species produced a 35 kDa HSP, and four species produced HSPs with molecular weights of 30 kDa, 28 kDa and 22 kDa. When subjected to heat shock treatments at 40°C, thermophilic and thermotolerant fungi synthesized mostly high and medium molecular weight HSPs while at 50°C, they synthesized mostly low molecular weight HSPs.
