Abstract The studied problem is of commercial interest because whey, the cultivation substrate, is a waste by-product from the transformation of milk into cheese and casein. Investigations on the influence of the dilution rate (D) on the bioproductivity of lactose-utilizing yeasts were carried out with two model strains D the oxidative strain Candida blankii 35 and the fermentative strain Candida pseudotropicalis 11. The increase of D led to the different changes in productivity. The best synthesizing ability of both continuously cultivated strains is established at D = 0.4 [h-1] despite the different type of metabolism. The oxidative strain C. blankii 35 is more effective in comparison with the fermentative strain C. pseudotropicalis 11 because of its ability to synthesize 1.5 fold higher biomass and protein yields. These experimental facts were proved also by simulative research with a Fuzzy Knowledge-Based System (FKBS) developed for modeling the influence of D on several process variables.

Due to increasing antimicrobial resistance, functionally substituted cyclohexane derivatives are being explored as potential antimicrobial agents. Reaction of diethyl 4 - hydroxy - 6 - (hyd - roxyimino) - 4 - methyl - 2 - phenylcyclohexane - 1,3 - dicarboxylate with 4 - toluene sulfonyl chloride in boiling acetone in the presence of equimolar triethylamine resulted in formation of diethyl - 4 - hydroxy - 4 - methyl - 2 - phenyl - 6 - ((tosyloxy)imino) cyclohexane - 1,3 - dicarboxylate. The structure of novel compound was characterized by 1 H and 13 C NMR spectra and elemental analysis was performed. Agar well diffusion assay was used to screen novel compound against Gram - positive bacteria, Gram - negative bacteria and fungi. Test compound showed better antimicrobial properties against Gram - negative bac teria as compared to Gram - positive bacteria and fungi. Acinetobacter baumannii BDU - 32 was found to be most sensitive bacteria while Candida pseudotropicalis BDU MA88 was found to be most sensitive yeast.
