FUNGI PADA BAMBU KUNING (Bambusa vulgaris Schard var. vitata) DAN BAMBU HIJAU (Bambusa vulgaris Schard var. vulgaris) SERTA TINGKAT DEGRADASI YANG DIAKIBATKANNYA

Abstract

The culm and leaf of Bambusa vulgaris Schard var, vitala (yellow bamboo) and Bamhusa vulgaris Schard var. vulgaris (green bamboo) were tested to identity their durability toward fungi or field. This research was carried out at the laboratory of Microbiology and Biochemist, Centre of Life Science and Faculty of Forestry, Bogor Agricultural University, indonesia. Colonization and biodegradation processes of culm of both bamboos used in this experiment was the trapping method. Observation was conducted every week for 12 weeks during incubation period. A degradation level was measured based on a decrease of dry weight of culm before and after trapping. Founded fungi was then isolated and identified. The results showed that Schizopyllum commune was dominant species to colonize and to degrade culm of yellow and green bamboos, whereas Trichoderma sp. was dominant species to colonize and to degrade leaf of yellow and green bamboos. The degradation levels of culm yellow bamboo were 19.9%, whereas the degradation levels of culm green bamboo were 45.7%. The highest degradation level of culm occurred 5-6 weeks after incubation on yellow bamboo (3.6%), and 11-12 weeks on green bamboo (4.3%).
