Abstract

U ovom istraživanju proveden je uzgoj biomase bakterije Azotobacter chroococcum za pripremu biološkog gnojiva. Proces optimizacije sastava kemijski definirane hranjive podloge proveden je da bi se odredio sastav koji je najadekvatniji za uzgoj bakterije u bioreaktoru. Tijekom ovog istraživanja za uzgoj bakterije A. chroococcum primjenjene su različite tehnike uzgoja, a njihovom međusobnom usporedbom na osnovi pokazatelja uspješnosti bioprocesa utvrđeno je da je polukontinuirani uzgoj najefikasniji način uzgoja, te stoga najadekvatniji za industrijsku primjenu.

Abstract (english)

In order to use bacterial biomass for biofertilizer preparation cultivation of Azotobacter chroococcum was done. Optimization of synthetic medium content was performed to define the most appropriate medium content for bacterium cultivation in bioreactor. In this research, different cultivation techniques were used for cultivation of bacterium A. chroococcum. Comparison between these cultivation techniques was done on the basis of bioprocess efficiency parameters and it was observed that repeated batch techniques is the most efficient and appropriate for use in industrial scale.
