The paper presents the results of a study of cultural characteristics of the strain A/equine/Otar/764/07 (H3N8) of equine influenza virus isolated from sick horse during the outbreak of equine influenza epizooty in the Republic of Kazakhstan. The studies determined the optimal culture conditions for equine influenza virus strain A/equine/Otar/764/07 (H3N8) in MDCK cell culture. The optimal infe...

Three different case studies addressing the specification of system performance and estimation of optimal cultivation policies are examined for different yeast cultivation systems. In the first case, the industrial production of baker’s yeast in bubble columns serves as illustration of primary model conception and exemplifies task-oriented reduction of model complexity. Within this simplified m...

Counting bacteria in natural water samples by cultivation yields only low recovery efficiencies (ca. 1%), compared to total counts obtained after 4,6-diamidino-2-phenylindol (DAPI) staining. In order to optimize the cultivation of heterotrophic planktonic bacteria from Lake Constance (Germany), selected parameters of the medium composition were modified. The most important factor was the concen...

The effect of substrate concentration, pH and cultivation time on the production of endoxylanase from Aspergillus awamori ZH-26 were optimized by statistical analysis using response surface methodology (RSM). Endoxylanase production was optimized by central composite rotary design. Statistical analysis of the results showed that the linear and quadratic terms of these three variables had signif...

Various cultivation parameters were optimized for the production of extra cellular protease by Brevibacterium linens DSM 20158 grown in solid state fermentation conditions using statistical approach. The cultivation variables were screened by the Plackett-Burman design and four significant variables (soybean meal, wheat bran, (NH4)2SO4 and inoculum size were further optimized via central compos...
