With the availability of the 600K Affymetrix Axiom high-density (HD) single nucleotide polymorphism (SNP) chip, genomic selection has been implemented in broiler and layer chicken. However, the cost of this SNP chip is too high to genotype all selection candidates. A solution is to develop a low-density SNP chip, at a lower price, and to impute all missing markers.

Two lipases (Lip A and Lip B), were purified from a commercial lipase preparation produced by Candida rugosa and partially characterized. The purified lipases were immobilized on Duolite A 568 and used in the selective esterification of cholesterol with free fatty acids from sardine fish oil. The results showed that Lip A and Lip B preferentially esterified saturated and monounsaturated fatty acids allowing a 3.

Article Synopsis
  • Isolated a lipolytic strain from palm fruit identified as Rhizopus oryzae, achieving optimal lipase production of 120 U/ml after 4 days, with purification resulting in a specific activity of 8800 U/mg.
  • The enzyme has a molecular mass of 32 kDa, optimal activity at pH 7.5 and 35°C, while showing stability at 45°C for 30 minutes.
  • The purified lipase effectively hydrolyzes saturated fatty acids and performs selective esterification of sardine free fatty acids, achieving 76% esterification and high recovery of docosahexaenoic acid (DHA).
