• Celeribacter strains are capable of methionine and DMSP degradation to widespread sulfur volatiles, but the analysis of trace compounds in natural samples must be taken with care. Keywords: GC–MS; isotopes; Roseobacter; sulfur metabolism; volatiles; Introduction Bacteria from the roseobacter group belong to

• into sulfur volatiles [24][25]. Notably, DHPS is produced in large quantities by the marine diatom Thalassiosira pseudonana [26], and diatoms from this genus live in symbiotic relationship with bacteria of the roseobacter group [27]. Another interesting aspect of sulfur metabolism in marine bacteria

• relationship during which the antibiotic TDA and growth stimulants are produced to a pathogenic interaction promoted by lignin degradation products in fading algal blooms that induce roseobacticide biosynthesis [36]. All these examples demonstrate the importance of sulfur metabolism for marine bacteria from

• sulfur atoms of TDA. This result together with mutations of relevant genes of the primary sulfur metabolism pointed towards an introduction of sulfur from Cys via (S)-thiocysteine (73) into TDA. Antimycins such as antimycin A1 (79) are known for their inhibitory effect on the respiratory chain [83] and

• methaneselenol-derived volatiles via reduction and methylation. The pathway of selenate/selenite reduction, however, proved to be strictly separated from sulfate reduction.

• ]. The cooperation of phenylacetate degradation and sulfur metabolism is manifested in the production of the antibiotic tropodithietic acid (TDA, 8) [7][8] and the roseobacticides, a class of algicides, represented by, e.g., roseobacticide A (9) [9][10]. The high abundance of sulfur volatiles throughout
