The group also considered mesh sizes and minimum sizes regulations for all species of bottomfish, and the Russo-Japanese fishery in the Eastern...
Cathepsins are intracellular proteinases that hydrolyze the
peptide bonds of proteins. These enzyme have been implicated in
the tenderization of aging beef, with the deterioration of radiation-stabilized
meats on storage, and in the spoilage of fish prior to
processing. Hence, the cathepsins of edible muscles are of concern
to the...
The capabilities of the coagulation-filtration process for virus
