Bioremediation of gasoline contaminated soil by a bacterial consortium amended with poultry litter, coir pith and rhamnolipid biosurfactant

Biodegradation of n-hexadecane by bacterial strains B1 and B2 isolated from petroleum-contaminated soil

“…Pseudomonas aeruginosa has been widely studied and is known to produce a glycolipid type of biosurfactant [34,35]. Rhamnolipids are amphiphilic surface-active glycolipids that are usually secreted in the growth medium [36,37], but can potentially be used to combat marine oil pollution [8]. Figure 5 shows that the value of MATH increased from 0.71 to 0.91 when B1 was cultured with hexadecane.…”

Towards efficient crude oil degradation by a mixed bacterial consortium

“…The flasks were incubated in a shaker at 200 rpm at 30°C for 20 days. At every 2 days interval, set of flasks were used for the enumeration of microbial population by pour plate technique on plate count agar (Hi-Media, India) and estimation of crude oil content by the method of Rahman et al (2002). The total hydrocarbons in the treatments were determined spectrophotometrically.…”

The Potential of Bacterial Isolates for Emulsification with a Range of Hydrocarbons

“…Hence, biosurfactant producing microorganisms may play an important role in the accelerated bioremediation of hydrocarbon contaminated sites (3)(4)(5). These compounds can also be used in enhanced oil recovery and may be considered for other potential applications in environmental protection (5,6).…”

“…Hence, biosurfactant producing microorganisms may play an important role in the accelerated bioremediation of hydrocarbon contaminated sites (3)(4)(5). These compounds can also be used in enhanced oil recovery and may be considered for other potential applications in environmental protection (5,6). Other applications include herbicides and pesticides formulations, detergents, health care and cosmetics, pulp and paper, coal, textiles, ceramic processing and food industries, uranium ore-processing and mechanical dewatering of peat (1,2,7).…”
