“…2). Similar to the results of this investigation [14,[25][26][27][28][29][30][31][32][33][34][35], the literature suggests that neutrophilic degraders prefer a pH range of 6 to 8.0 for SDS degradation or growth. At a pH of 9.5, the growth of the bacterial consortium drastically slowed, likely because of the extremely alkaline circumstances.…”

“…1). Similar to the results of this study [14,[25][26][27][28][29][30][31][32][33][34][35], mesophilic degraders often grow best at temperatures between 25 and 35 °C when degrading or growing SDS.…”

“…Bacteria capable of decomposing SDS have been documented in the literature, and there is a wide range of species. includes Acinetobacter calcoaceticus and Pantoea agglomerans [36], Pseudomonas betelli and Acinetobacter johnsoni [37], Klebsiella oxytoca [38] as well as Burkholderia sp., and Serratia odorifera [39,40] and many more [14,[25][26][27][28][29][30][31][32][33][34][35]. SDS can be degraded by a psychrotolerant bacterium even at temperatures below 10 degrees Celsius [41].…”

“…2 g/L of ammonium sulfate was maximum. Nearly all SDSdegraders, including many mesophilic degraders [14,[25][26][27][28][29][30][31][32][33][34][35], require a simple nitrogen source like ammonium sulfate to maintain development on SDS.…”

During biodegradation, microorganisms can directly metabolize surfactants for energy and nutrients or co-metabolize them with other compounds. Maximum growth of the bacterial consortium on SDS was seen between 30 and 35 °C, while the optimal pH range for bacterial consortium growth was between 6.5 and 7.5. As for the nitrogen source, 2 g/L of ammonium sulfate was optimum in supporting the growth of SDS. The greatest growth rate of the bacterial consortium was recorded at a concentration of between 1 and 1.5 g/L of SDS (p<0.05). At 2–3, g/L of SDS, the bacterial consortium grew more slowly, and at 5 g/L, growth was severely inhibited. Almost complete degradations of SDS were observed in 3, 5 and 6 days at 0.5, 0.75 and 1 g/L SDS, respectively while higher concentrations showed partial degradation with no degradation observed at 2.5 g/L SDS after 6 days of incubation. In this study, the maximum growth rate, or max, Ks, and Ki were 0.517 h-1 (95% confidence interval of C.I. from 0.404 to 0.629), 0.132 (g/L) (95% C.I. from 0.073 to 0.191) and 0.909 (g/L) (95% C.I. from 0.544 to 1.273), respectively. Heavy metals like mercury, copper, and chromium can severely stunt growth if they are present in the environment. It was discovered through research into growth kinetics that Haldane substrate inhibition kinetics may be used to model the growth rate. This bacterial consortium has the right properties for the bioremediation of SDS-polluted environments.

Excessive use of detergents in wide industrial processes results in unwanted surfactant pollution. Among them, sodium dodecyl sulphate (SDS) has well-known history to be used in pharmaceutical and industrial applications. However, if discharged without treatment, it can cause toxic effects on living organisms especially to the aquatic life. Floating treatment wetlands (FTWs) could be a cost-effective and eco-friendly options for the treatment of wastewater containing SDS. In this study, FTWs mesocosms were established in the presence of hydrocarbons-degrading bacteria. Two plant species (Brachiaria mutica and Leptochloa fusca) were vegetated and a consortium of bacteria (Acinetobacter sp. strain BRSI56, Acinetobacter junii strain TYRH47, and Acinetobacter sp. strain CYRH21) was applied to enhance degradation in a short-time. Results illustrated that FTWs vegetated with both plants successfully removed SDS from water, however, bacterial augmentation further enhanced the removal efficiency. Maximum reduction in SDS concentration (97.5%), chemical oxygen demand (92.0%), biological oxygen demand (94.2%), and turbidity (99.4%) was observed in the water having FTWs vegetated with B. mutica and inoculated with the bacteria. The inoculated bacteria showed more survival in the roots and shoots of B. mutica as compared to L. fusca. This study concludes that FTWs have the potential for the removal of SDS from contaminated water and their remediation efficiency can be enhanced by bacterial augmentation.

A bacterium capable of degrading sodium dodecyl sulphate (SDS) isolated from a paddy field water is characterized. In this report, we showed that almost complete degradation of SDS was observed in 6 to 10 days when the bacterium was grown on medium supplemented with SDS ranging from 0.75 to 1.75 g/L while higher concentrations showed partial degradation with no degradation was observed at concentrations higher than 2.0 g/L. The SDS-degrading bacterium was partially identified and provisionally named Pseudomonas sp. strain Maninjau1. We also showed that the presence of metal ions such as silver, copper, cadmium, chromium, lead and mercury inhibit the ability of the bacterium to degrade SDS by 50%. Growth kinetic studies show a correlation coefficient value of 0.99 for the Haldane model indicates it fits the curve while a low correlation coefficient value of 0.67 for the Monod model indicates poor fitting. The specific growth rate μ was discovered to rise as the substrate concentration was increased but it reached a peak value followed by a slow decrease indicating substrate inhibition. The calculated qmax or maximum degradation rate was 0.917 h-1 (95% confidence interval or C.I. from 0.664 to 1.171) while the saturation constant Ks or half velocity constant was 0.178 g/L SDS (95% C.I. from 0.089 to 0.266). The inhibition constant Ki was 0.605 g/L SDS (95% C.I. from 0.358 to 0.941). The very high maximum degradation rate obtained in this study indicates that this bacterium can be an efficient agent for bioremediation of SDS especially in soils.
