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, trof the first order reation model [4] was 53 h for free-living cells and 112 h for particle-associated ones. The value of trmay 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. © 1990.
