Abstract
1. Forty-three strains of moulds, selected from ten species, were examined to ascertain their capabilities as producers of fat, when grown in four different solutions of nutrient inorganic salts together with sucrose. The three highest yields of felt were given by Penicillium javanicum van Beyma, P. Soppi Zaleski, and Aspergillus nidulans Eidam, in that order. The fat content on felt weight was maximal at 34·8 per cent, with P. Soppi , at 28·4 per cent. with Fusarium lini (1), and at 25·8 per cent. with A. nidulans ; on sugar utilized it was maximal at 11·4 per cent. with P. Soppi , at 7·9 per cent, with A. nidulans , and at 5·6 per cent. with F. lini (1). 2. Other moulds considered worthy of further trial were P. spinulosum, P. aurantiobrunneum, F. graminearum, A. flavus, F. oxysporum, A. clavatus, and P. oxalicum.
