Abstract

Torula herbarum (PERS.) LINK Ex. Fr. is a dermataceous fungus regularly associated with dry leaves and twigs of Felia microphylla LIEBM. In submerged cultures the organism produces weakantimicrobial substances whengrown n CZAPEK's or in a malt extract medium. The temperature range for the growth of the organism was found to be 24-28°C and no growth occurred at 5° or 37°C. Nitrogen and carbon utilization studies indicated tyrosine and levulose to be the best sources, followed by ammonium tartrate and glucose respectively. Based on these studies a synthetic mediumwas developed for the optimum production of pigments.
