Nevertheless, identical results were observed in the control after
28 days of fermentation. It has been reported by Riebroy, Benjakul,
and Visessanguan (2008) that MHC was significantly degraded
during the ripening of fermented fish. Actin in the samples fermented
with mixed starter cultures was degraded more remarkably
compared with that in the control during fermentation. A
lower band intensity of actin was discerned during 28 days of
fermentation. The bands at 29.2 and 20.1 kDa were observed
during fermentation, which might be attributed to the comigration
with degraded high-molecular-weight proteins. This
result is consistent with that reported by Casaburi et al. (2007)
that the inoculation with the strains of S. xylosus CVS11, Lactobacillus
curvatus AVL3, S. xylosus FVS21 affected the protein degradation
of Italy fermented sausages profoundly. Furthermore, MHC
was more susceptible to proteolysis than actin, which has also
been verified by Verplaetse, Demeyer, Gerard, and Buys (1992) and
García de Fernando and Fox (1991).
