Abstract

The differences of morphological and physiological characteristics of Trametes spp. isolated from the forest at Sungai Rayu Matang Wildlife Centre, Sarawak were studied. Twenty one expected species of Trametes have been collected. T. versicolor. T multicolor and Trametes. sp 24 were the most common Trametes species found. Nine selected isolates of Trametes spp. were used for physiological studies. Growth rates of Trametes on different media, incubated temperature, carbon, nitrogen, phosphate and potassium sources were varied depending on isolates. Among three media used, the highest growth rates of the isolate were on either PDA or MEA. All species were able to grow on the tested media except for Trametes. sp 24 which did not grow on CMA. The highest growth rates of Trametes species were at 25 'c to 35 'CO There was no growth at 40 'C except for T.e/egans. Trametes were able to grow on diverse carbon sources and without carbon sources. The most efficient carbon sources for Trametes to grow were sucrose, starch and lactose. Peptone and yeast were the most efficient nitrogen sources compared to NaN03, KN03 and without nitrogen. Media with KN03 plus KH2P04 was the most efficient used by Trametes for phosphate taken by the fungi compared to other potassium sources. KH2P04 was the best potassium source for Trametes growth.
