[Antiadhesive properties of the surfactants of Acinetobacter calcoaceticus IMB B-7241, Rhodococcus erythropolis IMB Ac-5017, and Nocardia vaccinii IMB B-7405].
Attachment of the cells of some bacteria, yeasts, and micromycetes to various surfaces (catheters, dentures, plastic, polyvinyl chloride, tiles, and steel) treated with the surfactants fromAcinetobacter calcoace- ticus IMB B-7241, Rhodococcus erythropolis IMB Ac-5017, and Nocardia vaccinii IMB B-7405 was studied. Adhesion of microorganisms to all the studied surfaces depended on the surfactant concentration and purity, kind of surface, and the test culture. Treatment with the surfactants from N. vaccinii IMB B-7405 (0.005- 0.05 mg/mL), A. calcoaceticus IMB B-7241 (0.003-0.036 mg/mL), and R. erythropolis IMB Ac-5017 (0.03- 0.12 mg/mL) resulted in adhesion decreased respectively by 35-75, 60-75, and 25-90% for bacteria (Es- cherichia coli IEM-1, Bacillus subtilis BT-2, etc.), by 80-85, 55-90, and 15-60% for yeasts Candida albicans D-6, and by 40-50, 35-45, and 10-20% for micromycetes (Aspergillus niger P-3 and Fusarium culmorum T-7).
