Summary

The film-submerged reactor (FSR) is a modified “Gorbach fermenter” (Gorbach 1969). Using this reactor at low rotation speed, good yeast growth was reached on n-alkanes. The biomass yield by Candida oleophila was more than 7 g/l from 1% alkanes in 48 h. Low aeration resulted in slow growth but high biomass yield, high aeration resulted in quick growth but lower yield. The optimal rotation frequency at tested conditions was 32 rpm. Alkane concentrations greater than 1% decreased the growth of C. oleophila. The influence of pH-regulation was not important, whereas the age of inoculum cultures showed significant influence on growth velocity.
