The assimilation and transformation of phytoplankton-derived organic sulfur compound dimethylsulfoniopropionate (DMSP) by bacteria during the microcosm experiment and relation between the changes in DMSP processing and the changes in the composition of the bacterial assemblage during the induced bloom compared to nonbloom conditions are investigated. The results show that the composition of the bacterial assemblage and the contribution of DMSP to the overall dissolved organic sulfur/organic matter pool control how efficiently bacteria assimilate DMSP S and thereby potentially divert it from DMS production.

Cloning, sequencing, and heterologous expression of the cyclothiazomycin biosynthetic gene cluster from Streptomyces hygroscopicus 10-22 is reported. The rigorous bioinformatics analysis based on heterologous expression of cyclothiazomycin led to an ideal biosynthetic model to better understand the biosynthesis of thiopeptides.

The growth of Cupriavidus necator H16 with isethionate is seen along with inducible membrane-bound isethionate dehydrogenase (IseJ) and inducible transcription of the genes predicted to encode IseJ and a transporter (IseU). Biodiversity is observed in isethionate transport genes and is examined by transcription experiments.
