• Selective Microbial Degradation of Saturated Methyl Branched‐Chain Fatty Acid Isomers

  AbstractThree strains of Pseudomonas (P.) bacteria were screened for their capabilities of degrading chemically synthesized saturated branched‐chain fatty acids (sbc–FA). Mixtures of sbc–FA with the methyl‐branch located at various locales along the fatty acid were used as a carbon feedstock in shake‐flask culture. Utilization (and hence degradability) of the sbc–FA was monitored based on positive bacterial growth, fatty acid recovery rates and chromatographic (gas chromatography (GC) and GC‐mass spectroscopy (MS)) analysis of the recovered carbon source. P. putida KT2442 and P. oleovorans NRRL B‐14683 were both able to grow on sbc–FA utilizing 35 wt% and 27 wt% of the carbon source, respectively after 144 h. In contrast, P. resinovorans NRRL B‐2649 exhibited the most efficient use of the carbon source by utilizing 89 % of the starting material after 96 h resulting in a cell dry weight (CDW) of 3.1 g/L. GC and GC–MS analysis of the recovered carbon source revealed that the bacterial strains selectively utilized the isostearic acid in the sbc–FA mixture, and a new group of C10, C12, C14 and C16‐linear and/or branched‐chain fatty acids (approximately 4–29 wt%) were formed during degradation.

  A process for preparing saturated branched chain fatty acids or alkyl esters thereof involving subjecting unsaturated fatty acids having 10 to 25 carbon atoms, alkyl esters thereof or mixtures thereof to a skeletal isomerization reaction in the presence of water or a lower alcohol at a temperature of about 240° C. to about 280° C. using a combination of a stericly hindered Lewis base and zeolite as a Brönsted or Lewis acid catalyst, and isolating saturated branched chain fatty acids or alkyl esters thereof or mixtures thereof from the reaction mixture obtained by the skeletal isomerization reaction. The yield of said saturated branched chain fatty acids is ≧70 wt %. The stericly hindered Lewis base is a tertiary amine or phosphine with linear or branched C1 to C6 alkyl or phenyl groups attached thereto.
