Bracken, Pocker & Raistrick (1954) described the isolation of two nitrogen-containing products from different cultures of Penicillium cyclopium Westling. One of these, previously isolated from Penicillium viridicatum Westling by Cunningham & Freeman (1953) and named viridicatin, C15H11NO2, was shown to be 2,3-dihydroxy-4phenylquinoline or its keto-tautomer (I), by degradative methods and unequi...

I t has been known for some time that Penicillium citrinum Thom when grown on suitable media produces a characteristic lemon yellow colour. Thus Thom in his monograph on “ Cultural Studies of species of 1910), says, “ P. citrinum produces a lemon yellow colour, soluble in alcohol, in media containing sugars, milk, gelatin, bread and potato.” This colouring matter was not isolated, however, nor ...

In the following paper an account is given of the investigation of the metabolic products formed from glucose by various species of fungi belonging to different genera. These species were chosen for investigation since the carbon balance sheets prepared for them, when grown on Czapek-Dox glucose solution, indicated that each of them gives rise to considerable quantities of some metabolic produc...

THE name Aspergillus terreus is used by Thom and Church [1918; 1926] to cover a series of strains which have a number of well-marked morphological features in common, but which show a certain amount of variation in colour and type of growth. The conidial colour may range from pale cinnamon to fairly deep brown; the texture of the surface growth may vary from smooth velvety to definitely floccos...
