File Name : fig.s1_red.tiff Caption : figure s1. biomass growth (optical density at 600 nm, od600) of the isolated bacterial strains pseudomonas chlororaphis pss4, p. proteolytica wbrs105, p. veronii wbrs70, p. brenneri wbrs 96, janthinobacterium lividum wbrs30, and kluyvera intermedia wbrs56. an inoculum of 10% (v/v) of a growing pure culture was transferred to fresh minimal denitrifying medium and incubated at 10℃ under anoxic conditions. data are shown as means and standard errors (n = 3). doubling times (td) were calculated from biomass growth during the exponential phase.
