title: [Antimicrobic features of phenolic lipids].
abstract: The connection between the efficiency of phenolic lipids (PL) and their hydrophobic property (solubility) and hydrophobic property of microorganisms' cell structure is shown. The mixture of amphiphilic di(oxiphenil)-phenil-methanes, which act bacteriostatically under 15 mg/l, possesses maximal efficiency against Staphylococcus aureus. Against Mycobacterium smegmatis with hydrophobic cell wall, hydrophobic 2,4-dialkylocibenzol 70 mg/l was the most effective. Hexylresorcin (HR) stops the development of gram-positive bacteria in concentrations 20-50 mg/l, that of gram-negative bacteria in concentration 65 mg/l, that of M. smegmatis at 70 mg/l, and that of yeast and fungi at 300 mg/l. HR prevails bacteria spores germination in the concentration 25-100 mg/l. The dependence of antibacterial action of isomers and homologues of alkylresorcins on their structure--number, position, and length of alkyl substituents--is studied.
