The Importance Of \Omega-3 Series Fatty Acids In Marine Fish Larvae Nutrition And Recent Developments, Abdurrahman Polat, Gülsün Özyurt
The Importance Of \Omega-3 Series Fatty Acids In Marine Fish Larvae Nutrition And Recent Developments, Abdurrahman Polat, Gülsün Özyurt
Turkish Journal of Veterinary & Animal Sciences
In general, marine fish larvae require \omega-3 HUFA, especially eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Larval growth, survival and larval activity are affected by dietary levels of essantial fatty acids. Some pathological signs, such as abnormal pigmentation, hydrops etc. and low feed conversion efficiency, poor growth, mass mortality are related to \omega-3 HUFA series fatty acids deficiency in larvae food. EPA/DHA ratio in live foods or microencapsuled diets is an important factor in larval development and survival.

Biochemical Characterization Of Elastase Frompseudomonas Aeruginosa Ses 938-1, Semra Kocabiyik, Ezgi Ergi̇n
Turkish Journal of Biology
We have investigated some biochemical properties of elastase from a new strain o f Pseudomonas aeruginosa (SES 938-1). Activities were measured at 410 nm using N-succinyl-L-(ala) 3 -p- nitroanilide as substrate. The elastase activity followed Michaelis-Menten kinetics over the substrate range of 0.067-0.540 mM with the apparent K m value of 0.375 mM. Optimum activity was observed at 36 °C and pH 7.5. elastase activity was inhibited by metal chelating agents and high concentrations of Mn 2+ , Zn 2+ and Ni 2+ . The results obtained suggest that elastase from P. aeruginosa SES 938-1 is a neutral metalloproteinase.
