“…Therefore, since S5 strain is not spores producing bacterium [21], efficient immobilization in the presence of glucose probably resulted from synthesis of adhesins which are involved in attachment of cells to the carrier. Bacteria of genus Planococcus are known to be moderately halophilic [26][27][28]. Recent research [23] shows that osmotic stress favours the formation of biofilm by Planococcus rifietoensis by increasing production of exopolysaccharides (EPS), which additionally improves water holding capacity at higher salt concentrations.…”

Planococcus sp. S5, a Gram-positive bacterium isolated from the activated sludge is known to degrade naproxen in the presence of an additional carbon source. Due to the possible toxicity of naproxen and intermediates of its degradation, the whole cells of S5 strain were immobilized onto loofah sponge. The immobilized cells degraded 6, 9, 12 or 15 mg/L of naproxen faster than the free cells. Planococcus sp. cells immobilized onto the loofah sponge were able to degrade naproxen efficiently for 55 days without significant damage and disintegration of the carrier. Analysis of the activity of enzymes involved in naproxen degradation showed that stabilization of S5 cells in exopolysaccharide (EPS) resulted in a significant increase of their activity. Changes in the structure of biofilm formed on the loofah sponge cubes during degradation of naproxen were observed. Developed biocatalyst system showed high resistance to naproxen and its intermediates and degraded higher concentrations of the drug in comparison to the free cells.

The effect of temperature on benzene removal efficiency was not significant during the first year of operation, and the seasonal benzene removal efficiency was almost unchanged for both the indoor and outdoor wetlands (Fig.…”

“…Processes such as adsorption, biodegradation and volatilisation contributed to benzene removal (Corley et al 1996;Lee et al 2004;Li et al 2006). Concerning adsorption removal, no obvious temperature dependencies were observed and negligible differences in benzene removal efficiency at 4°C, 10°C and 20°C were detected in industrial wastewater adsorption studies (Adachi et al 2001).…”

Studies on the anaerobic and aerobic growth of Alcaligenes eutrophus bacteria show that the same growth factor suffice for both aerobic and anaerobic growth, thus supporting Mathava and Ligy formulation of photosynthesis and carbon assimilation in these forms, and his thesis that the previously observed need for peptone or yeast extract could be attributed to their content of essential growth factors. A bottle technique for anaerobic cultures and a flask technique for aerobic culture are described in detail. Photosynthesis in A. eutrophus bacteria is best observed when they are grown anaerobically. The experiments described here indicate that the culture media had to be modified to conform to certain special requirement imposed by anaerobic growth; the required growth factors remained the same. A. eutrophus bacteria display the same growth pattern in both aerobic and anaerobic condition in ethylene substrate while there were some slight changes of its growth pattern in both aerobic and anaerobic condition for xylene and benzene substrate which are aromatic compounds. This study shows that there was higher growth of A. eutrophus bacteria in aerobic condition than anaerobic condition. The findings suggest that A. eutrophus bacteria is most adapted to conditions present in soils contaminated with gasoline and hence can be exploited in bioremediation activities.
