title: Production and utilization of extracellular slime by Pseudomonas solanacearum and its role on survival at different relative humidities.
abstract: Pseudomonas solanacearum produced maximum slime with glucose and least with glycerol. With increasing concentration of glucose, slime production increased. The maximum slime production was observed in the medium containing 1% glucose. The slime contained sugars, sugar acids and amino acids. The bacterium utilized the slime as a sole source of carbon. The growth on slime was more or less comparable to the growth on 0.1% glucose. The viability of the bacterium in slime increased as the relative humidity (RH) decreased. At higher RH the slime absorbed moisture and the viability was reduced. The bacterium could survive only for short period at higher RH under sunlight not in shade. The sunlight seemed to accentuate the harmful effect of RH on the bacterium.
