The dependence between the development of qualitative and quantitative composition of the microbial consortium from wheat feed, rapeseed cake, soybean cake and their mixture and the ambient humidity level was determined. These results demonstrated the dominant microorganisms that comprise the natural microflora of secondary raw materials of grain, oilseed and legume crops processing plants. The Bacillus genus phyla (Firmicutes type) are dominant in mixed substrates (feed+cake). The prolongated cultivation under high humidity conditions identified bacterial cultures with morphological features different from the bacterial forms of Bacillus clausii, Bacillus sp. and Nocardiopsis sp. dominant in the secondary raw materials under study. It appears that the growth of these cultures increased in response to the development of specific substrates — microbial consortium products. The increase in the storage duration of the analyzed secondary raw materials under high humidity conditions causes changes in their microbiological composition and activity levels of α-amylase, invertase, phytase, proteases, lipase and β-glucanase synthesized by indigenous microorganisms. This indicates the mobility of the microbial consortium enzyme system affected by the secondary raw materials components chemical nature. The development of water-soluble forms of polymeric molecules such as polysaccharides (β-Glucans including forms (1,3)(1,6)-β-D- and (1,4)(1,3)-β-D-) and esters (phytic acid, phytate) in plant and microbial biomass generated from the interaction of microbial consortia and substrate components of secondary raw materials at elevated humidity implies the decomposition of microbial biofilms. Enzymatically active plant and microbial substances are potential food ingredients, in particular, they act as quality enhancers for raw food. [ABSTRACT FROM AUTHOR] |
