Abstract

Fatty acids and carotenoid has been known as an anticancer agent on both preventing and treating cancer disease. This study was conducted to analyze the fatty acid profile, carotenoid and in vitro anticancer activity of 12 sea cucumber harvested from Karimunjawa and Lampung waters. The aim of the study was to determin the potency of sea cucumbers as raw material for nutraceutical products. Fatty acid profile and carotenoid content were characterized by gas chromatography and spectrophotometry techniques, while in vitro anticancer activity was assessed by MTT assay against cervix (HeLa), breast (T47D and MCF-7) and colon (WiDR) cancer cells. Results of the study showed polyunsaturated fatty acid (PUFA) dominated the composition of fatty acids in the samples from both locations. Holothuria sp. was detected to contain the highest amount of carotenoid. Furthermore, the highest in vitro anticancer activity was detected also in the sample of Holothuria sp. The activity of 30 ppm Holothuria sp. extract against HeLa cell was detected to be almost equal to the 5 ppm doxorubicin control. Concentration of 5 ppm Holothuria sp. extract also showed positive result in killing 50% of MCF-7 and T47D, but capable to 100% kill HeLa and WiDR cells. At concentration of 25 ppm, the extract was able to kill all the 4 cells tested. Statistical analysis showed the amount of carotenoid and two particular fatty acid compounds (docosadienoic and eicosapentaenoic acid) significantly (P0.05) contributed to the cytotoxic activity that was found in the sea cucumber samples. Those compounds were found in highest concentration from Holothuria sp harvested from Lampung waters, thus being the most prospective raw material for nutraceutical or functional food ingredient with anticancer potency.

Abstract

Streptomyces sp. TTA 02 SDS 14 is a transglutaminase producing bacteria which previously had been  screened along with more than one hundred isolates. This research aimed to purify and characterize transglutaminase from this strain. Transglutaminase was purified from crude enzyme by ultrafiltration, Q-Sepharose ion exchange chromatography and Sepacryl S200 size exclusion chromatography sequentially, obtaining yield and purification fold of  1.36%  and 27 folds, respectively. The molecular weight of the purified transglutaminase was 72 kDa detected by zymogram gel electrophoresis. The optimum temperature and pH were 50°C and 6. The transglutaminase was stable at 45°C and could be activated in the presence of 5 mM and 10 mM of Na+, K+, Li+,Ca2+, Mg2+, BPB (4-bromo-phenacyl bromide), and IAA (iodo acetamide acid), but the activity was inhibited by  the presence of Cu+, Zn2+, and PMSF (phenyl methyl sulfonyl fluoride).

Abstract

Several xylanases have already been studied. However, only a few xylanases derived from marine microorganisms has been reported. Marine bacterium LBF-001 was isolated from Pari Island Kepulauan Seribu, Indonesia. The purpose of this study is to identify isolate LBF-001 using 16S rDNA gene and to optimise the medium conditions for the xylanase production i.e. concentration of biomass, nitrogen source, pH and temperature. Based on 16S rDNA gene analyses, LBF-001 isolate has 99% similarity with Bacillus pumilus HNS70 (KF933667). Fermentation process to produce xylanases was conducted using several agricultural residues under solid-state fermentation (SSF). The optimum condition for xylanase production by B. pumilus LBF-001 was using a medium containing  2.5% empty fruit bunch and 0.6% lactose broth, at pH 6.5, temperature 30 oC, under submerged fermentation with shaking at 150 rpm for 48 h fermentation. The optimised condition resulted higher xylanase activity, i.e. 10.85 U/mL.

Abstract

Study aimed to investigate the utilization of shrimp shell powder in the production of lindur fruit-potato simulation chips, which was assessed using proximate composition, texture performance and sensory evaluation parameters. Three different ratios of lindur fruit-potato flour (w/w) (30:70, 40:60 and 50:50), as well as different concentrations of shrimp shell powder (0, 1, 3 and 5%) were used in the formula. The results showed that lindur fruit-potato simulation chips enriched with shrimp shell powder had 3.22-4.42% moisture content, 3.33-4.94% ash content, 3.77-5.83% protein content, 14.59-19.04% fat content, 71.06-76.34% carbohydrate content and 341.4-530.9 g/cm2 hardness. Ratio lindur fruit flour and potato flour of 40:60 as well as 3% of shrimp shell powder was chosen as the best treatment since the formula produced lower hardness, higher protein content and the most crispy and tasty chips preferred by panelists.

Abstract

 Study on chemical content of swamp fishes from Merauke has been conducted to obtain nutritional status  of these fishes. Sampling was conducted  twice (August and November 2015) in Merauke. There were six dominant fish species, namely striped snakehead (Channa striata), nile tilapia (Oreochromis niloticus), tade gray mullet (Liza tade), philippine catfish (Clarias batrachus), barramundi (Lates calcarifer), and climbing perch (Anabas testudineus). Result on proximate analysis showed that the fishes had moisture content of 75.73±0.25%-81.45±0.04%, ash 0.94±0.01%-1.26±0.21%, protein 17.11±0.09%-18.92±0.05%, and lipid 0.59±0.19%-3.80±0.63%. The dominant essential amino acid of 6 swamp fishes from Merauke was lysine followed by leucine. Meanwhile the dominant non-essential amino acid was glutamic acid (32.26+0.61 mg/g), followed by aspartic acid. Calcium (Ca) was the dominant macro mineral for all fishes studied, being the highest was in nile tilapia (328.76±8.14 mg/100 g). Micro mineral was dominated by the presence of Selenium (Se) which the highest was in nile tilapia (0.084±0.005 mg/100g). These fishes were also rich in albumin, being the highest was stripe snakehead (138.59±1.68 mg/g). The average of total fatty acid showed that the fishes had saturated fatty acid (SFA) content of 46.30±0.27%, monosaturated fatty acid (MUFA) 9.20±1.6%  and polyunsaturate fatty acid (PUFA) 34.49±0.44% of total fatty acid. From the result, it can be concluded that fish harvested from swamp of Merauke and surrounding area had a good nutritional value.
