Assimilation of C10 - C13 n - alcanes by yeast.Peer-reviewed article

J. RYBÁŘOVÁ, A. ČEJKOVÁ

The mixture of n - alcanes consisting of n - decane, n - undecane, n - dodecane and n - tricedane has been used as a substrate for cultivating 40 selected strains of yeast. Five straines gave high yields of biological substance ranging from 60,8 to 64,8 %, nineteen strains produced from 50 to 59 %, whereas the rest failed to produce more than 20,3 - 48,7 %. The specified yields were compared with yields produced by the same strains cultivated in a hydrocarbon substrate containing higher hydrocarbons, viz. 97,5 % of n - alcanes of which   70 % were represented by C₁₅ - C₁₉ group. Using as a criterion the behaviour of various strains in two substrates all studied strains have been classified and divided in three groups. The results of experiments confirm that a substrate containing lower hydrocarbons ranging from C₁₀ to C₁₃ is a good culture medium, in which certain strains of yeast can give high yields of biological substance.
