Solonamides, a Group of Cyclodepsipeptides, Influence Motility in the Native Producer Photobacterium galatheae S2753.

The marine bacterium Photobacterium galatheae S2753 produces a group of cyclodepsipeptides, called solonamides, which impede the virulence but not the survival of Staphylococcus aureus. In addition to their invaluable antivirulence activity, little is known about the biosynthesis and physiological function of solonamides in the native producer. This study generated a solonamide-deficient (Δ) mutant by in-frame deletion of the gene, thereby identifying the core gene for solonamide biosynthesis.

Draft Genome Sequences of Nine Environmental Bacterial Isolates Colonizing Plastic.

Here, we report the draft genome sequences of nine bacterial isolates obtained after laboratory incubation of seawater, soil, and wastewater samples with polylactic acid, polyethylene, or polyethylene terephthalate film for 2 weeks. Assuming colonization as a prerequisite of degradation, these strains could contribute to a solution to the global plastic waste problem.
