Abstract

Sea cucumbers are a potential source of bioactive metabolites for nutraceutical, pharmaceutical and cosmeceutical products. In this study we investigated the antioxidant activityof several extracts of sea cucumbers, Holothuria scabra, Holothuria atra, Holothuria leocospilota, and Holothuria excellens collected from Lombok Island. Phytochemical screening revealed the presence flavonoid, terpenoids, phenol, saponin, alkaloid, anthraquinone and glycoside in the extracts of Holothuria sea cucumbers. Radical scavenging effects on the DPPH model were evaluated. The crude extract of H. leocospilota and H. atra showed the highest potential antioxidant capacity. H. atra extract was separated by column chromatography silica gel eluting with a gradient system of increasing polarity. Fraction 7 of H. atra extract showed significantly inhibited radical scavenging activity (35.3487 %) at concentration 1 mg/ml. However, these are preliminary findings and further studies will have to focus on the isolation of bioactive substances derived from H atra and identify other health benefit effects of H. atra.

Abstract

The marine bacteria were cultured in liquid medium under shaking condition were extracted with ethyl acetate. Antidiabetes was measured using inhibition of α-glucosidase inhibitory activity method; antioxidant was measured using DPPH free radical scavenging activity method; antibacterial was tested using disc diffusion method.S creening results showed that at sample concentration of 200 µg/ml, there was significant α-glucosidase inhibitory activity was detected in the extracts of strain sp 7.9 (84% inhibition) and 8.10 (75% inhibition),however the antioxidant activity of these two strains were low only around 30% inhibition, antioxidant activities of other strains were very low.Screening for antibacterial activities using 10µl samples showed that extract of strain Sp 8.5was best for Staphylococcusaureus (14 mm inhibition); Sp 7.9 and Sp 8.5 for Bacillus subtilis (18 mm inhibition); Sp 8.10 for Escherichia coli (10 mm inhibition); Sp 8.9 and Sp 8.10 for Pseudomonas aeuriginosa. Based on these results marine bacteria strain Sp 7.9 and Sp 8.10 were selected to be used for further studies in the isolation of bioactive that has potential as antidiabetes and antibacterial.Results of molecular identification conducted by INACC showed that identity of both strain based on BLAST Homology using NCBI database were Bacillus thuringiensis strain Ou2.

Abstract

Polycyclic Aromatic Hydrocarbons (PAHs) as well as crude oil are widespread environmental pollutants. The contamination of air, soil, freshwater (surface water and groundwater), and marine environments by PAHs as well as crude oil has been reported. Of concern to public health is the fact that many PAHs or their metabolites are mutagenic, carcinogenic, or both. North Java coastal area such as Jakarta Bay is the polluted marine area in Indonesia as a result from anthropogenic wastes and the oil spill. Although evaporation and photo-oxidation play an important role in oil detoxification, ultimate and complete degradation is accomplished mainly by marine micro flora, and being dominant in this function. Certain bacteria are well-known could consume and degrade the PAHs as well as crude oil. Therefore investigating the potential PAH and oil degrading marine bacteria is important. In this study, we collected sample from oil polluted area in Marina Port Ancol, Jakarta Bay and isolated four PAH substrates and Arabian crude oil degrading marine bacteria using enrichment method and direct isolation method. As result, 223 strains could degrade PAHs, among these strains, 94 strains could degrade phenanthrene, 23 strains degrade fluoranthene, 92 strains could degrade dibenzotiophen, 14 strains could degrade phenotiazin and 106 isolates degrade crude oil.Key words: polycyclic aromatic hydrocarbons, crude oil, degrading bacteria, bioremediation.
