Study IDST000258
Study TitleMetabolic contribution of pSymA and pSymB megaplasmid/chromid for multipartite Sinorhizobium meliloti cultured in minimal M9 medium
Study Typemegaplasmid deletion
Study SummaryTo understand the contribution of pSymA and pSymB to the metabolism of S. meliloti, the intracellular metabolome was analyzed at five time points (exponential and stationary growth phases) across the growth curve of strains with or without pSymA and/or pSymB grown in a defined, minimal medium (M9).
