Abstract

Cardiovascular disease is the number one cause of death and disability worldwide. The purpose of this experiment was to create local ducks egg enriched with omega-3 as a candidate of nutraceutical to prevent cardiovascular disease. Sixty local ducks were randomly distributed to six treatment with three levels of fish oil (0 ppm, 1500 ppm, and 3000 ppm) and two levels of tomato meal (0 ppm and 150 ppm) in a 3x2 factorial arrangement. Data of local ducks performances were analyzed using two-way Anova, data of egg yolk omega-3 fatty acid content was analyzed descriptively. There was an interaction (p<0.05) of fish oil and tomato meal supplementation on egg weight. Supplementation of 3000 ppm fish oil +150 ppm tomato meal tend to increase DHA content of egg yolk with 0,43% compare than control treatment with 0,18%. The conclusion of this research supplementation of 3000 ppm fish oil +150 ppm tomato meal could produce egg yolk of local ducks egg with 0,04% ALA and 0,43% DHA.Keywords:  cardiovascular disease, DHA, local ducks egg, fish oil, tomato meal

Abstract

Pseudomonas has the potential ability for production of citrate synthase synthesis. Pseudomonas aeruginosa could synthesize the enzyme of citrate synthase which is most likely compatible with microalgae cell. Pseudomonas aerugenosa can be found in the rhizosphere of Kruing (Dipterocarpus sp., Dipterocarpaceae). This bacteria is commonly used in agriculture purposes because it is able to synthesize organic acid such as citric acid. These organic acids are synthesized from a reaction between oxaloacetate and acetyl CoA, catalyzed by citrate synthase (CS) in the tricarboxylic acid cycle (TCA). Rhizosphere as microbial sources was obtained from Kruing (Dipterocarpus sp.), which was collected from ?Carita? Research Forest, Pandeglang, Banten, West Java. Citrate synthase gene-specific primers were designed based on citrate synthase gene sequences as depicted in Genbank. The isolation and amplification showed that citrate synthase can be detected and purified from Pseudomonas aeruginosa target and it consists of 1600 bp and encodes 509 amino acids. Based on BLAST (Basic Local Alignment Search Tool) analysis, CS genes that were successfully isolated had 92 % similarity with Pseudomonas aeruginosa type II citrate synthase. This CS gene is expected to be expressed in microalgae metabolism to divert the metabolism of carbohydrate formation into fatty acids.
