The reducing sugar content of each fruit juice sample increased after treatment by pectinase (Table 10), which is probably related to the liberation of reducing sugar after the degradation of pectin compounds.

Many other aspects of the pathogenicity and virulence of S. marcescens have been studied, including adherence and hydrophobicity, lipopolysaccharide (LPS) and extracellular products. Serratia marcescens is negative for acid production on lactose, but positive glucose and sucrose (with gas production) fermentation. Nitrate tests are positive since nitrate is generally used as the final electron acceptor rather than oxygen . Citrate (positive test) is used by Serratia marcescens to produce pyruvic acid.

The endobj With 10mg of protein concentration, the maximal activity was 47.32 U/mg, suggesting that the protein molecules separated by ammonium mainly contained the enzyme pectinase and that the proportion of protein other than pectinase was higher in the crude form of the enzyme [11, 31, 44]. 32(3):90-7.
