Abstract : Physiological studies pertaining to the effect of physical factors, carbon and nitrogen requirements of Arthrinium phaeospermum was conducted to know its behaviour in vitro. These studies have revealed interesting results regarding its growth and reproductive behaviour. The best medium for the optimum growth of the fungus is Glucose-peptone medium. The optimum temperature (28°C) and pH (8.0) is required for the optimum mycelial production of Arthrinium phaeospermum after 14 days of incubation. The best carbon source for the growth of the fungus is D (+) lactose whereas the fungus does not show any growth in L-sorbose medium. The best inorganic nitrogen source for the growth of the fungus is ammonium oxalate. The least mycelial growth of the fungus is observed in ammonium chloride and ammonium sulphate. The best organic nitrogen compound for the mycelial growth of fungus is L-proline. With L-tyrosine the fungus does not show any growth.

Keywords : Arthrinium phaeospermum, D (+) lactose, ammonium oxalate, L-proline.
