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...

Biofuels from micro-organisms represents a possible response to the carbon dioxide mitigation. One open problem is improve their productivity, in terms of biofuels production. To do so, an improvement present model growth and production required. However, this implies understanding spontaneous conditions bacteria. In paper, thermodynamic approach developed order highlight fundamental role elect...
