Characterization and expression levels of protease enzymes at different developmental stages of Siamese fighting fish (Betta splendens Regan, 1910)
Thongprajukaew, Karun; Kovitvadhi, Uthaiwan; Engkagul, Arunee; Torrissen, Krisna Rungruangsak (Journal article; Peer reviewed, 2010-05)Characterization of total proteases, trypsin and chymotrypsin were performed at pH 2 12 and temperatures 20-80°C in three life stages of Siamese fighting fish (Betta splendens Regan, 1910). At least fourteen protease ... -
Characterization of Digestive Enzymes from Adult Freshwater Pearl Mussel Chamberlainia hainesiana (Lea, 1856)
Khrueane, Wilailuk; Kovitvadhi, Uthaiwan; Engkagul, Arunee; Torrissen, Krisna Rungruangsak (Journal article; Peer reviewed, 2009)Freshwater mussel Chamberlainia hainesiana is a vulnerable species in Thailand.
