Digestive enzyme profiles of forgut and their differential between sexes of blue swimming crab, portunus pelagicus at Gelang Patah
(Universiti Malaysia Terengganu, 2014) Nordiana Pilus
Blue swimming crab, Portunus pelagicus consumed variety kind of food as their diet. The study shows that their dietary items are molluscs, crabs and seagrass, including unidentified items that semi-digested. They are categorized as cannibalism because they consumed other crabs where the parts of crab's appendages were found in their foregut. They are omnivore group, as they eat other animal, they also consumed plants. Amylase, protease, and trypsin were detected in all sample and stages, except lipase, indicate that P. pelagicus readily digest dietary protein and carbohydrate at all stages. The changes in enzyme activities between stages reflect the changes in natural diet and feeding abilities. High proteolytic activity reflects a diet high in protein as show by matured males (MA). Meanwhile, carbohydrase activity reflects a diet with starch or cellulose that consumed by all stages especially matured males (MA), females with ovarian stage two (S2) and immature males (IM). And the high lipase activity reflects a diet high in fat as shows by female with ovarian stage four (S4).

(Universiti Malaysia Terengganu, 2014) Rodhiyah Yahya
Natural products play an important role in production of new drugs, new drug leads and new chemical entities. Pandanus odoratissimus (Pandanaceae) is one of the most popular herbs and locally grows in Malaysia, and has been used traditionally to Ayurvedic medicine cure certain diseases. The present study is aimed to find out antioxidant and anticancer activity of P. odoratissimus against human breast cancer cell lines (MCF-7). Antioxidant activity has been measured by using 2, 2-diphenyl-1- picrylhydrazyl (DPPH) free radical scavenging activity and core showed highest antioxidant value among the other extracts. The effects of plant's parts on MCF-7 cell lines were determined using [3-( 4, 5-dimethylthiazolyl)-2, 5-diphenyl-tetrazolium bromide], MTT assay.
A study on protential application for antibacterial, antibiofilm and antioxidant from tissues of sea Cucumber (stichopus horrens)
(Universiti Malaysia Terengganu, 2014) Noor Fatin Osman @ Latif
Crude extract of Stichopus horrens's tissues that were collected from Bidong Island, Terengganu were evaluated for their antibacterial, antibiofilm and antioxidant. At the lower concentration of extraction from S. horrens 's tissue (0.234 mg/ml), the sample showed negative value in percentage inhibition which is -13.797 %. This indicate that the extraction of tissue from S. horrens do not possess antibiofilm activity at lower concentration. When increasing the concentration of sample, the percentage inhibitions also increase up to 49.456 %. However, the continued increasing the concentration of sample, the percentage inhibition are started to decrease to -15.544 %. There is no antibacterial activity detected in the S. horrens which is indicating by no inhibition zones were measured against eight types of bacteria tested. Only the controls which are ampicilin (gram-positive) and gentamycin (gram-negative) show the inhibition zone in all the types of bacteria used.

The studies of fatty acid content in plankton have been studied worldwide with different condition and climate especially in marine ecology. This method is very useful to trace the basic sources background in marine organisms. Fatty acid is important in as a source of energy in higher trophic level. The importance in this study was to determine the dominant plankton and to trace the fatty acid biomarkers in the natural plankton community with different mesh sizes.
Biosynthesis of biosurefactant by marine pseudomonas aeruginosa
(Universiti Malaysia Terengganu, 2014) Mohd Saifuddin Halim
This study emphasizes on the evaluation of the ability of the marine strain Pseudomonas aeruginosa to biosynthesize biosurfactant from the various carbon sources and to characterize the rhamnolipid produced. The need of viable alternatives from toxic synthetic surfactants are inevitable in the current status quo where environmental protection is being implemented. Biosurfactant provides an insight to this issue where its application does not produce adverse effects to the environment. The production of biosurfactant also opens up doors to utilize organic wastes as carbon source fuel for the biosynthesis process thus giving an additional value to these wastes. The study sees that the production of rhamnolipid is significant in all carbon sources with different capacity and concentrations. The diversity of the P. aeruginosa strain to survive in various terrain and condition may be a reason of the positive outcome from the tests. Collectively, the results obtained from this study may be able to provide additional information to the bettennent of biosurfactant study.
