Title: Use of Nitrogen-Supplemented Peat Extracts for the Cultivation of Pleurotus ostreatus Mushroom Mycelium

The first commercially oriented research on submerged culture production of mushrooms was carried out in 1948 (Humfeld, 1948). It was reported that a good commercial product can be grown on any medium that contains a suitable sugar and other essential nutrients, that does not contain an ingredient inhibitory or toxic to the growth of the microorganism, and that does not impart a characteristic flavour of its own during its use as a medium. Since then, there has been an attempt by many workers to improve the process of biomass production from higher fungi. Sugihara and Humfeld (1954) reported the submerged culture growth of several mushroom species. Eddy (1958) studied the growth of 20 species of mushrooms in synthetic culture. In a series of patents, Szuencs (1958), Humfeld (1954), and Cinllo (1960), disclosed methods for producing mushroom mycelium in submerged culture. The growth requirements of some wood-rotting fungi (Jennison et al., 1955) and some mushrooms (Whitaker, 1951) grown in submerged culture, have also been studied. Reviews of the work done m submerged culture of mushroom mycelium have been presented by Litchfield (1967a, 1968), and Worgan (1968). The cultivation of basidiomycetes in fermenters has been used in physiological studies in order to determine single parameters for biomass production, to produce special enzymes or as a screening program for antibiotics (Zadrazil and Grabbe, 1983). The potential of mushroom mycelium as fungal protein, source of spawn, or flavouring agent, makes their production in submerged culture an attractive prospect (Hadar and Cohen-Arazi, 1986).
