Example 2

Another wider test was completed using a method in which a piece of sugar snake (weight previously recorded) was incubated in chemistry containing surfactant. After a set time, the remaining sugar snake was removed and quantified by water displacement in a graduated cylinder. After treatment, sugar snake degradation was determined by subtracting the volume (mL) of water displacement from the starting weight (grams). Each variation was compared to a control where the surfactant was omitted. The same three terms as above (synergistic, compatible, and less favorable) were used to identify the enzyme compatibility of each surfactant. Results are shown in Table 4.
