Poly(3-hydroxybutyrate) influences biofilm formation and motility in the novel Antarctic species Pseudomonas extremaustralis under cold conditions
Polyhydroxyalkanoates (PHAs) are highly reduced bacterial storage compounds that increase fitness in changing environments. It has previously shown that polyhydroxybutyrate (PHB) accumulation is essential during the growth under cold conditions. In this work, the relationship between PHB accumulatio...
