Investigation on antibacterial activities of terpenoid and polysaccharide from Scleroderma citrinum Pers. Pers. and Tremetes versicolor Fr. Quel

Dr. Swapan Kumar Ghosh

Abstract :

Polysaccharides and terpenoids were isolatedfrom fruit bodies of basidiomycetous fungi Scleroderma citrinumPers. Pers. andTrametesversicolorFr. Quel.,which were collected from the plain of West Bengal,India.Their antibacterial activities were assayed by agar plates cup diffusion techniques against three Gram + ve bacteria (Staphylococcus aureus,Micrococcusroseus and Bacillus evis) and two Gram – ve bacteria (Ralstonia solanacearum and Escherichia coli ).Terpenoid isolated fromTrametesversicolorFr. Quelwas most active in inhibiting the growth of all five bacteria. Terpenoid inhibited maximum (19 �2.4mm)growth against Staphylococcus aureus and minimum against Micrococcus roseus (17�1.1mm). The MIC of terpenoid isolated from T. versicolor was 5�g/ml against S.aureus and R.solanacearum and it was similar to ampicillin (5�g/ml).The polysaccharides isolated from these two mushrooms were less active against the test five bacteria.The terpenoids isolated from Scleroderma citrinum Pers. Persalso inhibited the growth of the test bacteria.
