“…Initial oil ) × 100 (1) Surface tension of the BH media with three different oil systems were measured during the growth phase using stalagmometer (make: Borosil). Oil displacement study was carried out to confirm the presence of biosurfactant in the system [13]. Three Petri dishes, each containing 20 ml of BH culture broth were taken where 1 ml of free oil, 1 ml of coarse emulsion and 1 ml of microemulsion were added at the centre of each respective petridish.…”

The present study investigates the bioremediation of waste engine oil at both dissolved or being suspended in oily wastewater using an actinobacterium, Gordonia terrae DSM 43249 strain isolated from East Kolkata wetlands. The isolated strain was found capable of sustaining in highly toxic oil contaminated wastewater and simultaneously can efficiently biodegrade the pollutants in both simulated fresh and marine water system at optimized environmental conditions. Moreover, in order to understand the effect of physical presence of oil in oily wastewater on the bioremediation process, three types of simulated oil-water forms were studied: water with free waste engine oil, oil-water mixture in the form of coarse emulsion and microemulsion. It was observed that the percentage degradation became maximum with the microemulsion form (72.73%) followed by the coarse one (65.45%). The minimum percentage degradation of 39.74% was seen with the free oil. Statistical interpretation also revalidates the experimental observations, showing that the oil percentage degradation is much sensitive to the oil and water composition in an oily-water system (F=772.64> Fcritical =5.143). Hence, it is presumed from the present study that such a high percentage degradation of oil especially, when oil is thoroughly mixed with water, can be considered as one of the potential applications for oil treatment such as during oil spillage using G.terrae DSM 43249.

Used engine oil (UEO) contains potentially toxic substances that harmful humans and the ecosystem. Its dangerous pollution requires customized, efficient adsorptive bioremediation. This study investigates the local soil bacteria that can remove petrol-UEO (shell 15–40) by metabolic capability in UEO-YEMSM, previously isolated from UEO-polluted soil in KL, Malaysia. The biosorptive bioremediation capabilities of the free cell (FC) formula for UEO have been studied using pure Ochrobacterium intermedium LMG 3301 and mixed culture consortia of Ochrobacterium intermedium LMG 3301 plus Bacillus paramycoides MCCC1A04098 (BC), with an inoculation size of 3 × 109 CFU/mL in 0.675% (v/v) UEO-YEMSM. To study the UEO adsorption bioremediation of IC systems and compare them to the same FC systems, pure and mixed bacteria cells were immobilized using alginate-attapulgite-calcium carbonate (AAC). On day 24, the IC systems exhibited the removal of nC9 to nC17 with a 30% increase in TPH obtained with O.intermedium and the 18% by O. intermedium + B. paramycoides (BC) in UEO, as compared to the same FC systems. The AAC-IC of O. intermedium and the BC also removed nC9-nC29 to 93% and 98%, demonstrating the adsorptive-biosorptive bioremediation capacity of IC-systems with efficient mass transfers of experimental effectiveness factor (η) values of 1.04, and1.05, close to FC system η = 1. The enhanced degradation and bacterial growth in the AAC-IC systems indicated the high potential of AAC beads to be applied in the insitu bioremediation of UEO-polluted soils/water environments in KL, Malaysia.
