DESCRIPTION: \n\nPhD Oral defense of Nana Akyaa Ackaah-Gyasi\, Food Science
  and Agricultural Chemistry\n\nChymotrypsins are widely distributed among 
 living species and have found widespread use in different industrial appli
 cations. However\, until the last two decades\, most studies on chymotryps
 in have been restricted to mammalian species with few reported works on ma
 rine invertebrates.  The high catalytic activity of some aquatic enzymes a
 t low temperatures\, coupled with high pH and the relatively low thermal s
 tability makes them robust in certain industrial applications where cold t
 emperatures are preferred. In this study\, chymotrypsin was purified to ho
 mogeneity and characterized from the viscera of two squid species (Loligo 
 opalescens\, cold water adapted and Sepioteuthis lessoniana\, warm water a
 dapted). Cold adapted chymotrypsin can transform substrates at low tempera
 ture thereby reducing loss of organoleptic properties and nutritional valu
 e of heat-sensitive substrates and products mostly found in industrial pro
 cessing of food such as fish. They also provide economic benefit through e
 nergy savings during processing. This study also looks at the possibility 
 of producing the enzymes using recombinant DNA technology\, since it is cu
 rrently not feasible or practical to extract these proteases from crude so
 urces such as viscera for commercial application.\n\nEveryone in the McGil
 l community is welcome to attend a PhD oral defense. Please join us in cel
 ebrating the accomplishments of our PhD candidates.\n\n \n\n \n
