Biochemical Indicators of the Transportation Stress of the South African Abalone (Perlemoen), Haliotis Midae, Linn

Abstract

Abalone exposed to air incurred greater metabolic and structural stress in muscle than do abalone at rest. Since foot and shell adductor muscle texture and flavor affect economic values of H Midae, the investigation sought evidence of differences attributable to transport of the commercial South African abalone based on environmental and exercise inducement. Tauropine dehydrogenase from Haliotis. midae muscle exhibits its highest activity 53.85 X 13.56 U g-1 wet weight in shell adductor muscle. The activities of octopine dehyedrogenase, strombine dehydrogenase or alanopine dehydrogenase in adductor muscle were very low. Therefore, tauropine dehydrogenase was isolated from adductor muscles for enzymatic determination oftauropine. Tauropine dehydrogenase was purified 8.5-fold with 47% recovery.
