1.4.3. Zygomycetes Biomass Components
The microbial biomasses of zygomycetes from family of Rhizopus oryzae ordinary contain a
high concentration of Chitin/Chitosan in cell wall. The cytoplasmic components contain proteins,
Unsaturated C18 triglycerides, some vitamins and some other components respectively [13] .
Determination of TFM (Total fatty matter) showed total fatty matter of biomass sample was 10-
20% (w/w) [13] , which main amounts contain 70-80% unsaturated 18 carbon fatty acids, such as
oleic acid, linoleic and linolenic acids, respectively.
Further analysis was shown that zygomycetes protein is one of the complete sources of amino
acids in nature which can use as food-stuffs. The amino acids of zygomycetes protein are
presented in Table 3. The protein concentration according to our experimental work was 47.7%
of the dry weight of biomass (see section3.1.Ⅱ).
1.4.4. Zygomycetes Proteins
The Rhizopus oryzae contains various kinds of proteins and enzymes. Table 3 shows the types
and percentage of amino acids in the zygomycetes mycellum. The main enzymes are including
amylase, isomerase, protease, dehydrogenase, hydratase and lipase*. These enzymes help to
decompose of macromolecules to short fragments in order to catalytical reactions. Also they are
able to hydrolyzing the bacterial proteins so its antimicrobial effects due to destruction of
bacterial plasma membrane.
