Comparing the yields of fruit juice produced from different types of fruits using Pectinase. Background Knowledge: Fruits are made of a relatively simple plant cell, with thin walls made of two layers. The primary cell wall is made with cellulose fibres surrounded by a matrix of pectin, hemi cellulose and proteins. The second and inner wall is similar but contains less pectin. Between the two layers is a binding layer of pectin. The complete removal of this layer causes the tissues to fall apart. This is the reason for why fruits and vegetables become soft over a period of time. Long chains of pectin are broken down by digestive enzymes produced by bacterium such a "soft rot". Cellulose is also vulnerable to enzymatic attacks especially in the primary cell wall as its arranged at random compared to the stronger regular pattern form in the second cell wall. Breakdown of cellulose leads to...
