Abstract
Various fatty acids of branched nature possess fungistatic and bacteriostatic properties. Some of these, particularly those of
iso
-configuration, strongly enhance the effect of conventional antimicrobial agents that act inside the cell membrane. A relation between this biological effect and the collapse properties of the corresponding monomolecular surface film on water has been observed. In this work, a series of fatty acids with a slightly smaller end group than
iso
-propyl, the ω-cyclopropane fatty acids, as well as one possessing a somewhat larger end group, the
neo
-branched fatty acids, have been examined. The ω-cyclopropane fatty acids were found to be more fungistatic than the
iso
-acids studied earlier. Furthermore, both cyclopropane and
neo
-fatty acids of short chain lengths exhibited synergistic effects in combination with tetramethylthiuramdisulfide.
