among 10 coccolithophores tested, DLA is restricted to Emiliana huxleyi and Gephyrocapsa oceanic. If DLA is restricted to a subset of coccolithophores, then those species are more likely to emit DMS directly in the sea. In ecosystems where coccolithophores form stable populations, species other than Emiliana huxleyi can make significant contributions to the particulate dimethylsulfionopropionate pool and hence hence to the amount of dimethylsulfionopropionate potentially available to the microbial loop |

Sulfitobacter J443, DddL-mutant has lost its Ddd+ phenotype, showing that this species has no other gene that can substitute for dddL, the wild type produces 385 nmol dimethylsulfide, the mutant produces only 0.7 nmol dimethylsulfide |
