Abstract
Sodium
dodecyl sulfate (SDS) is one of the main components in the detergent and
cosmetic industries. Its bioremediation by suitable microorganism has
received greater attention. Pseudomonas aeruginosa MTCC 10311 was isolated
from detergent contaminated soil which had degraded 96% of SDS in 48 hrs.
Attempts were made to study the metabolic byproducts of SDS degradation using
GC-MS analysis. Analysis of ether extracts of surfactant established the
sequential production of Dodecanol, Dodecanal and Decanoic acid. At this
point, the pathway diverged into the formation of acid residues through beta
oxidation. This SDS degrading isolate, Pseudomonas aeruginosa can be
exploited for decontamination of detergent contaminated waste water.
