Traditional nitrogen-fixing biofertilizers have suffered from problems of short shelf life and Instability during storage periods. The Azotobacters cyst can be survive and retains for over two years. The inoculums used were preserved in liquid form which has great advantages such as that they can be easily applied through irrigation system; seed treatment and soil application. The microbes move directly into the root zone and become immediately available to the plant and suitable for foliar application, higher quality, and longer shelf-life rather than those of carrier based inoculants. The...

The book aimed to reveal degradation of Cucurbitacin E glucoside obtained from Citrullus colocynthis (L.) (Hanzal) into Cucurbitacin E and glucose by mean of microbial biotransformation using Curvularia lunata NRRL 2178 as a source of -glucosidase. All the instrumental data obtained by highly advanced techniques, confirmed the microbial conversion of cucurbitacin E glucoside into cucurbitacin E and glucose indicating effect of enzyme in the hydrolysis process by splitting of glucose from the anomeric carbon atom. The effect of the cucurbitacin E glucoside and cucurbitacin E on the...
