TY - CONF A1 - Breitenbach, Romy A1 - Toepel, Jörg A1 - Vandrich, Jasmina T1 - The role of c-di-GMP in biofilm formation of the filamentous cyanobacterium Nostoc punctiforme N2 - The signaling molecule c-di-GMP is a ubiquitous second messenger in bacterial species including cyanobacteria. C-di-GMP stimulates the biosynthesis of extracellular polymeric substances (EPS) in biofilms and regulates the transition between a motile and a sessile life style in many bacteria. In our study we focus on c-di-GMP function and EPS production associated with biofilm Formation in Nostoc punctiforme, which is known to produce EPS in biofilms and liquid culture.

These complex polyphenols play important roles in stress tolerance while being essential components of fungal cell walls and useful biomarkers. Here we report signatures of melanins and carotenoids in pigment mutant strains of the black yeast Knufia petricola A95 using Raman spectroscopy T2 - 11th Workshop of FT-IR Spectroscopy in Microbiological and Medical Diagnostics CY - Berlin, Germany DA - 19.10.2017 KW - Raman KW - Melanin KW - Rock-inhabiting fungus PY - 2017 AN - OPUS4-43124 LA - eng AD - Bundesanstalt fuer Materialforschung und -pruefung (BAM), Berlin, Germany ER -
