Plasticizers are among the most important additives required for processing of
polymer materials. In this paper, biotechnological synthesis of adipic plasticizer – dioctyl
adipate was presented with the participation of yeast biomass of Yarrowia lipolytica KKP
379. The reaction was based on transesterification of dimethyl adipate with octan-1-ol.
Relative to the whole-cell catalyst were used both physical (treated with glass beads) and
chemical (use of isooctane and Triton X-100) methods of permeabilization. The research
confirmed the possibility of the synthesis of dioctyl adipate catalyzed by whole cell yeast
with the yield 60% (58% ±1,8%). The permeabilization techniques used did not contribute
to increasing the reaction efficiency. Among the methods of violating the continuity of the
yeast cell wall, the chemical method using Triton X-100 is of interest. Approximately 50%
conversion was achieved in this reaction and no decrease in yield was observed during 96
hours of reaction, as opposed to other methods permeabilization.
