3.2. Immunological response
The relative mRNA expressions of proPhenoloxidase (proPO),
lysozyme, and serine proteinase (SP) in hepatopancreas of Fenneropenaeus
chinensis were demonstrated in Fig. 2. The gene expression
of proPO was significantly increased over 120% bio-floc
concentrations, compared to the control. In the gene expression of
lysozyme, a considerable increase was observed over 120% bio-floc
concentrations. The gene expression of SP was significantly
elevated at 140% bio-floc concentration
