GROWTH AND AROMA PRODUCTION BY CERATOCYSTIS-FIMBRIATA IN VARIOUS FERMENTATION MEDIA

The ability of Ceratocystis fimbriata to generate aroma notes from dif ferent carbon and nitrogen sources was studied in liquid culture. The medium that gave the best sensory results produced a strong banana aro ma. Other notes such as pineapple, apple, pear and nuts, with varied, intensities were obtained from other culture media. Biomass and metabo lite productions are reported. In solid state fermentation, the mould was,grown on wheat bran, sugar cane bagasse and a synthetic resin (Amb erlite IRA 900) imbibed with a nutritive solution. Mould respirometry was used as growth indicator. While growth was regular, the aromas wer e not strong as those obtained in liquid culture.
