P. Christen et al., Characterization of volatile compounds produced by Rhizopus strains grown on agro-industrial solid wastes, BIORES TECH, 71(3), 2000, pp. 211-215
Four edible Rhizopus strains were cultivated on eight combinations of solid
agro-industrial wastes (cassava bagasse, apple pomace), soyabean, amaranth
grain and soyabean oil. Significant differences in growth were observed am
ong strains on the different media studied. The medium containing cassava b
agasse with soyabean (5:5 w/w) gave the highest CO2 production, while Rhizo
pus oryzae ATCC 34612 was the best producer of volatiles. The aromas of the
cultures were light and rather pleasant. The amaranth medium with mineral
salts solution produced the highest amount of volatile compounds (VC), demo
nstrating that the aroma of fermented solid substrates can be improved. The
VC production was very rapid, attaining, in most of the cases, its maximum
around the first day of culture. These maxima markedly varied according to
the medium used. (C) 1999 Elsevier Science Ltd. All rights reserved.
