Classification of cassava into bitter" and "cool" in Malawi: from farmers perception to characterization by molecular markers" por Mkumbira, J., Chiwona-Karltun, L., Lagercrantz, U., Mahungu, N.M., Saka, J., Mhone, A., Bokanga, M., Brimer, L., Gullberg, U., Rosling, H.

“…We studied how well these farmers comprehend the effects of genetic variations in cassava when dealing with cyanogenesis in this complex system. Using molecular markers we show that most plants farmers identified as belonging to a particular named cultivar had a genotype typical of that cultivar. …”

Plasmin and plasminogen variation in bovine raw milk : impact of season, breed and milking system por Khaled, Jaafar

“…Plasmin (PL) is a native proteinase in milk, which combines a complex system consisting of its zymogen called plasminogen (PG), inhibitors and activators, which activity is known to make considerable changes in the dairy products, which represent in irregulating of casein hydrolysis and poor clotting properties, that may slow the cheese ripening process and consequently increase the processing expense. …”
