SIFAT FISIK DAN KIMIA DARI ADITIF MINERAL ORGANIK UNTUK TERNAK HASIL FERMENTASI SACCHAROMYCES CEREVISIAE PADA SUBSTRAT YANG BERBEDA
Abstract: This research was
conducted to evaluate physical and chemical properties of organic mineral
additive incorporated by Saccharomyces cerevisiae which was cultivated on
different growth media consisted of cassava flour and rice bran, respectively.
Treatment was arranged on completely randomized design consisted of rice bran
without inoculants (RBo), rice bran with inoculants (RBi), cassava flour
without inoculants (CFo), cassava flour with inoculants (CFi). Substrates were
fortified by microminerals contained of Cu (100 ppm), Mn (100 ppm), Zn (100
ppm), I (10 ppm), Fe (2.5 ppm) and Co (2 ppm). Inoculation of S. cerevisiae
could reduce fungal contamination. Physical characteristic of cassava flour was
better in flavour and texture than rice bran in which tends to rancidity.
Nutrients composition was similar in cassava and rice bran however crude fibre
content in rice bran tends to be higher after fermentation. Mineral content (Zn
and Fe) relatively decreased and in substrate supplemented by inoculant and
rice bran had higher than cassava. In summary, micromineral was incorporated in
cassava flour with inoculated S. cerevisiae had better than rice bran.
