The cultivars selected for the study were Leccino, Messinese, Picholina, Etnea, Itrana, Coratina and Zatiuna. Standard protocols were followed for determination of quality parameters namely acid value, peroxide value, saponification value, iodine number and fatty acid profiles. The results obtained showed that the moisture content in the olive fruits decreased, whereas, oil content increased in all the olive cultivars under study as the maturity progressed. Furthermore, among the quality parameters of the oil studied, the iodine value was observed to decrease, while acid value, peroxide value, saponification value correlated positively with the maturity index. As regard to the fatty acid composition of the oil, level of palmitic acid decreased whereas the level of stearic acid and linoleic acid increased with the time of harvest. Oleic ac...

However, extraction of these compounds from native producers cannot meet the ever-increasing demands of the growing population due to, among other things, the limited production of the active compound(s). Their production depends upon the metabolic demands of the plant and is also subjected to environmental conditions, abundance of crop species and seasonal variations. Moreover, their extraction from plants requires complex downstream processing and can also lead to the extinction of many useful plant varieties. Microbial engineering is one of the alternative approaches which can meet the global demand for natural products in an eco-friendly manner. Metabolic engineering of microbes or pathway reconstruction using synthetic biology tools and novel enzymes lead to the generation of a diversity of compounds (l...
