1 Yellow media without gas pocket-sugar utilization with production of acid only. 2  Red media (no change in media) -no change and no sugar utilization. 3  Pink media especially at the top, ignore gas-no sugar utilization with degradation of protein resulting in alkaline end products (this may be difficult to see).
With organic solvents with long alkane chain, such as n-hexadecane and n-decane, the water droplets become much larger and the microemulsion is unstable. In this case, solvent polarity may have become a determining factor and the long alkane chain was too hydrophobic to form a stable microemulsion with water.
Abstract. The hexane extract of apple seed was analyzed by GCâMS and found to consist mainly of fatty acids (80.9%) in its volatile fraction with linoleic acid as the most dominant one (51.2%), followed by palmitic, linolenic, stearic and oleic acids (10.5, 5.6, 4.3 and 4.1%, respectively).bstract.
