“…The nature of the growth curve also showed that the growth rate of the bacterium increases with increasing volume of inoculum after 24 h incubation period. Similar findings were reported by [18,19] that highest growth and degradation of butachlor is achieved at high inoculum volume.…”

Butachlor is a chloroacetanilide herbicide that is selective in action and commonly used for pre-emergence control of weeds. It is believed to have range of toxicity from acute to chronic and also can cause DNA strand breaks and chromosomal aberrations in humans. This study was aimed at characterizing the potential of previously isolated bacteria for butachlor degradation. The isolates from culture collection, labelled A-F were screened for butachlor degradation on Bushnell Hass agar media with butachlor as a sole carbon source. Isolate A (molybdenum-reducing and aniline-degrading Pseudomonas sp.) was observed to grow best and tolerated the highest concentration of butachlor supplemented in the media after 72 h of incubation at 37 ℃. Characterization study revealed that the Pseudomonas sp. can utilize and grow with butachlor at optimum pH between 6.0 - 6.5, temperature between 30 – 37 ℃ and can tolerate up to 600 mg/L butachlor concentration with increase in growth as inoculum size increases. Additionally, this bacterial strain shows no lag phase regardless of the concentration of the herbicide used and reach its maximum growth after 24 h of incubation. The ability of this isolate to tolerate and utilize butachlor as sole carbon source makes it suitable for future bioremediation of this toxicant.

“…The synthetic microbial consortium, SMC1 formulated from the bacterial strains Serratia ureilytica AS1, Enterobacter cloacae FP2, and Pseudomonas putida G3, isolated previously from the soil samples of the contaminated sites, was used for the study. [23][24][25] The mineral salt medium (MSM) used for various studies was prepared as per the composition described previously. [26] The phosphate buffer saline (PBS) used during the preparation of calcium alginate beads was prepared as per the composition available in the literature.…”

In the present study, the effect of external mass transfer on the rate of butachlor biodegradation was studied using calcium alginate immobilized microbial consortium SMC1 in a re-circulated up-flow packed bed bioreactor in a batch scale. By assuming the biodegradation kinetics to be first order, the effect of various operational parameters such as feed flow rate, substrate concentration, and the external mass transfer on the bio-removal of butachlor from the aqueous medium has been explored. Using external film diffusion models and Colburn analogy, the mass transfer correlations at several feed rates were worked out. The correlational analysis obtained in the form of J D = 1.341 N − 0:3 Re was found to predict the experimental data precisely.
