Important Enzyme

Cellulase is one of the most economically important enzyme, which aids in catalyzing cellulolysis, the decomposition of cellulose and other related polysaccharides. So the demand/importance of this enzyme in both domestic and commercial sectors cannot be over emphasized. In this research cellulase-producing bacteria were isolated from soil around sugarcane waste dumping area, which was identified to be P. fulorescens after numerous biochemical and microbiological analysis. The bacteria were then grown and used to ferment certain biomass, with the aim of using the organisms to produce the cellulase enzyme. The total protein/cellulase enzyme activity of the medium was ascertained. Optimization/characterization for maximum cellulase activity was done by varying the temperature, pH, enzyme concentration and substrate concentration, in which the optimum condition for cellulase production was ascertain to be at a temperature and pH of 40˚C and pH 7 respectively. SDS-PAGE electrophoresis was carried out to determine and reconfirm the presence and molecular weight of the isolated enzyme. The estimated extrapolated molecular weight of the enzyme was found to be 13.5KDa.

Spinach grown in Texas developed “yellow spotting” on the peripheral portions of the leaves. The exact cause of the discoloration could not be determined as there was no evidence of viral or parasitic infestation of the plants and biochemical characterization of the plants did not indicate any significant differences between the yellow and green leaf portions of the spinach. The present study was undertaken using electron microscopy (EM) to determine if a micro-nutrient deficiency was the cause for the discoloration.Green leaf spinach was collected from the field and sent by express mail to the EM laboratory. The yellow and equivalent green portions of the leaves were isolated and dried in a Denton evaporator at 10-5 Torr for 24 hrs. The leaf specimens were then examined using a JEOL 100 CX analytical microscope. TEM specimens were prepared according to the methods of Trump et al.

SauvignonBlanc wine grape was characterized for their various morphological, physiological and biochemical parameters grafted on different rootstocks. Significant differences were recorded for all the parameters studied. The studies on vegetative parameters revealed that the rootstock influences the vegetative growth thereby increasing the photosynthetic activities of a vine. The highest photosynthesis rate was recorded in 140-Ru grafted vine followed by Fercal whereas the lowest in Salt Creek rootstock grafted vines.The rootstock influenced the changes in biochemical constituents in the grafted vine thereby helping the plant to store enough food material. Significant differences were recorded for total carbohydrates, proteins, total phenols and reducing sugar. The vines grafted on1103-Pshowed highest carbohydrates and starch followed by 140-Ru,while the least amount of carbohydrates were recorded in 110-R and Salt Creek grafted vines respectively.Among the different rootstock graft combinations, Fercal showed highest amount of reducing sugar, proteins and phenols, followed by 1103-P and SO4, however, the lowest amount of reducing sugar, proteins and phenols were recorded with 110-R grafted vines.The vines grafted on different rootstocks showed changes in nutrient uptake. Considering this, the physico-biochemical characterization of grafted vine may help to identify particularrootstocks combination that could influence a desired trait in commercial wine grape varieties after grafting.
