Abstract : "A trial was undertaken to study the relative effects of rations containing oil hydrogenated, a vegetable oil (mustard oil) and milk ghee on serum cholesterol of 30 recruits obtained from one of the Regimental Centers. The study was carried out for a total period of 3 months. The results of the study indicated that there is significant decrease in the average serum cholesterol of the subjects when they were maintained on rations containing vegetable oil. The study thus confirms the current trend and thoughts on the effect of diets high in saturated fat and low in essential fatty acids in increasing serum cholesterol as compared to a diet high in essential fatty acids." |

Abstract : A fungal strain, Syncephalastrum racemosum, was isolated from oil-leak contaminated soils from Kanpur, India. The strain was examined for potential to emulsify soybean oil using a 18 per cent oil supplement as carbon source in minimal salt medium. On 72 h growth of the fungus in oil and salt medium, the cellfree supernatant (CFS) showed presence of mono- and di-glycerides indicating degradation of oils to free fatty acids (FFAs). Increasing concentration of oil resulted in enhanced formation of FFAs. The degradation process was observed to be related to the emulsification activity in CFS which was observed to increase with time. The study reports the emulsification and hydrolytic activity of S. racemosum, an activity that can be exploited for increasing the accessibility and treatment of hazardous substance including hydrophobic explosives. |
