Abstract
A study was conducted to determine the specific growth rate sugar consumption and generation time of four diazotrophic bacterial species Burkholderia Rhizobium and two Corynebacterium spp. in four different carbon substrates. Growth of all bacterial strains was significantly affected by the sugars. Burkholderia sp. Sb13 rapidly attained maximum population in glucose fructose and sucrose and the specific growth rate best fitted with exponential model. The cell generation times of Burkholderia sp. Sb13 in glucose fructose and sucrose substrate were 0.4h 0.55h and 0.1h respectively. Rhizobium sp. Sb16 followed an exponential growth model in fructose and its generation time was 0.62h. The growth of Corynebacterium sp. Sb26 was highest in arabinose and followed the exponential growth model with generation time of 0.68h. Corynebacterium sp. Sb35showed faster generation time 1.0h in sucrose compared to other three substrates and the specific growth rate followed a logarithmic model.
