Biofilm formation was quantified using crystal violet staining, determined by colony-forming unit and examined by light microscopy. It was found that of bacterial surface hydrophobicity affects the biofilm formation: biofilm formation of Methylophilus quaylei MT strain was better on such hydrophobic materials as Teflon and polypropylene. The minimum inhibitory concentration of polymyxin B for the used strains in planktonic and biofilm form was 1 μg/ml. The sublethal Polymyxin B in the concentration of 0.01 μg/ml stimulates biofilm formation and exhibits antibiofilm properties at the concentration of 0.10 μg/ml. Synergistic effect of polymyxin B and streptomycin on streptomycin-resistant strain M. quaylei SM was found.</p></abstract><trans-abstract xml:lang="ru"><p>Исследовано влияние липопептидного антибиотика полимиксина В на рост чувствительного и резистентного к стрептомицину изогенных штаммов метилотрофной бактерии Methylophilus quaylei в планктоне и биопленке на полипропилене и тефлоне. Интенсивность образования биопленок определяли по окрашиванию кристаллическим фиолетовым, колониеобразующей способности, а также методом световой микроскопии. Обнаружено влияние гидрофобности клеточной поверхности бактерий на способность образовывать биопленки. На пластинах из тефлона и полипропилена более интенсивную биопленку образует штамм Methylophilus quaylei MT с гидрофобной поверхностью. Минимальная ингибирующая концентрация полимиксина В для изученных штаммов и в планктонной, и в биопленочной форме составила 1 мкг/мл. Полимиксин В в сублетальной концентрации 0.01 мкг/мл стимулирует образование биопленок, а в концентрации 0.10 мкг/мл проявляет антибиопленочные свойства. Обнаружено синергидное действие полимиксина В и стрептомицина на резистентный к стрептомицину штамм M. quaylei SM.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>бактериальные биопленки</kwd><kwd>полимиксин</kwd><kwd>резистентность к антибиотикам</kwd><kwd>метилотрофные бактерии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>bacterial biofilms</kwd><kwd>polymyxin</kwd><kwd>resistance to antibiotics</kwd><kwd>methylotrophic bacteria</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Costerton J.W.
