Journal ArticleDOI
Biodegradation of diesel/biodiesel blends by a consortium of hydrocarbon degraders : Effect of the type of blend and the addition of biosurfactants
Mikolaj Owsianiak,Łukasz Chrzanowski,Alicja Szulc,Jacek Staniewski,Andrzej Olszanowski,Agnieszka K. Olejnik-Schmidt,Hermann J. Heipieper +6 more
TL;DR: Emulsion formation experiments showed that biodiesel amendments significantly affected dispersion of fuel mixtures in water and the presence of rhamnolipids biosurfactant affected stability of such emulsions and altered cell surface properties of tested consortium.
Journal ArticleDOI
Biodegradation and surfactant-mediated biodegradation of diesel fuel by 218 microbial consortia are not correlated to cell surface hydrophobicity
Mikolaj Owsianiak,Mikolaj Owsianiak,Alicja Szulc,Łukasz Chrzanowski,Paweł Cyplik,Mariusz B. Bogacki,Agnieszka K. Olejnik-Schmidt,Hermann J. Heipieper +7 more
TL;DR: The effect of anionic rhamnolipids and nonionic Triton X-100 surfactants on biodegradation of diesel fuel employing 218 microbial consortia isolated from petroleum-contaminated soils indicates that in the surfactant-mediated biodegrades, effectiveness of surfactantes depends on the specification of microorganisms and not on the type of Surfactant.
Journal ArticleDOI
Secretory IgA in Intestinal Mucosal Secretions as an Adaptive Barrier against Microbial Cells
Bernadeta Pietrzak,Katarzyna Tomela,Agnieszka K. Olejnik-Schmidt,Andrzej Mackiewicz,Marcin Schmidt +4 more
TL;DR: This review presents mechanisms of SIgA generation: T cell-dependent and -independent; in different non-organized and organized lymphoid structures in intestinal lamina propria (i.e., Peyer's patches and isolated lymphoid follicles); and focuses on its role in regulating gut microbiota composition and generation of tolerogenic responses toward its members.
Journal ArticleDOI
Anti-Listeria activity of lactic acid bacteria isolated from golka, a regional cheese produced in Poland
TL;DR: The results indicate that golka cheese is a rich source of LAB active against Listeria, which may potentially find application as starter or protective cultures and could constitute a superb genetic pool for production of new bacteriocins.
Journal ArticleDOI
Interactions between rhamnolipid biosurfactants and toxic chlorinated phenols enhance biodegradation of a model hydrocarbon-rich effluent
Łukasz Chrzanowski,Mikolaj Owsianiak,Alicja Szulc,Roman Marecik,Agnieszka Piotrowska-Cyplik,Agnieszka K. Olejnik-Schmidt,Jacek Staniewski,Piotr Lisiecki,Filip Ciesielczyk,Teofil Jesionowski,Hermann J. Heipieper +10 more
TL;DR: The facts that rhamnolipids decreased diesel fuel – water partition coefficient of 4-CP and 2,4-DCP and modified aggregate size distribution profiles of the dispersed dieselfuel – chlorinated phenols solutions, suggest the existence of specific interactions between rhamNolipid and the co-contaminants.
