Abstract Free‐living cells produced colonies more rapidly than particle‐associated ones when a pure culture of Desulfovibrio desulfuricans containing sediment particles was inoculated on an agar medium. The time required for the appearance of the first colony, t r of the first order reation model [4] was 53 h for free‐living cells and 112 h for particle‐associated ones. The value of t r may be determined from the growth rate and sulfate reduction activity because the activity of free‐living cells was much higher than that of aggregating ones.
