Abstract

Fucoxanthin pigment is a potential compound in nutraceutical. It is commonly found in algaesuch as in Turbinaria sp.,a very abundant species in Indonesian coastal. To maximize theproduction of fucoxanthin for the development of nutraceutical industry in the coastal area, it isimportant to identify the optimal environmental parameters for its biosynthesis. It has been reportedthat nitrogen and or phosphate nutrients affect the growth of algae. Therefore, this paper aimed toobtain an optimal environment for Turbinaria sp. to produce fucoxanthin based on correlationanalysis. Correlated data were fucoxanthin isolated from Turbinaria sp.that was collected fromKrakal (Yogyakarta) and Binuangeun (Banten) coasts. Fucoxanthin contents in each sample werecompared based on the peak areas in chromatogram after 1 mg injection of n-hexane extract ofT. decurrrens in the HPLC system. The analysis results showed that the peak areas of fucoxanthinwere significantly different among sampling locations (P = 7.99 x 10-6), sampling periods (P = 6 x10-3) and interaction of both (P = 3 x 10-3). Whereas the correlation analysis revealed that interactionbetween phosphate and temperature could be a predictor that strongly (R = 0.986) and significantlycorrelated (P = 1.09 x 10-7) with the peak areas of fucoxanthin (R2= 96.5%). These results were inline with growth limiting factor in seawater and the function of fucoxanthin as ultraviolet protector.Based on these results, it is suggested that the suitable location for fucoxanthin production is in thearea of agricultural run-off that contains an elevated concentration of dissolved phosphate.

Abstract

Agar is polysaccharide extracted from the seaweed Gracilaria sp. It is commonly used for food, medical, pharmaceutical and biotechnology industries. The red seaweed Gracilaria verrucosa is the most common material used for the extraction of agar, processed into sheet and powder. A total of 7169 tons solid waste is produced from the agar industry in Indonesia which can further result in 4301.4 tons per year of cellulose. However, solid wastes from agar seaweed processing industry have not been managed and used optimally, and therefore seaweed solid wastes can be used as one of alternative source of cellulose and cellulolytic bacteria. In this research, we reported the isolation of cellulose-producing bacteria from seaweed processing industry wastes using specific media 1 % LIA (Limbah Industri Agar, waste of seaweed processing industry). Sequencing and subsequent phylogenetic analysis of the 16S rRNA genes amplified from the obtained 7 isolates identified them as Serratia marcescens, Chryseobacterium indovlogenes, Bacillus pumilus, Bacillus cereus, Strenatrophomonas maltophila, and Pseudomonas aeruginosa.

Abstract

Chitosan-starch blend film showed desirable elongation and oxygen transmission rate (OTR) values and demonstrated rapid degradation in soil burial treatment. The incorporation of higher glycerol concentration lowered tensile strength but increased the amount of transmittable water vapour. The biodegradability of chitosan-starch based film was tested using soil burial test. Chitosan-starch blend films were able to degrade naturally at slightly similar period, ranging from 72–87 days. The addition of glycerol was likely contributed to the high Water Vapour Transmission Rate (WVTR) value which faster the biodegradability of the film in soil. Among different type of acid solutions, lactic acid is less preferable solution to dissolve chitosan as it produced film with poor mechanical properties compared to acetic and formic acid. Based on its mechanical limitation, the film can be used as a coating based film for certain type of fish product, especially product with high lipid content.

Abstract

This experiment was conducted to study the effects of anthropogenic stressor on the spatialvariability of secondary metabolites from marine sponge Aaptos suberitoides. Samplings wereconducted at 7 sites in Marine National Park of Thousand Islands that are extended within 30 kmoff Jakarta bay on late February 2011. Sponges were collected and quantified by means of liquidchromatography coupled with photo-diode array detection, whereas, cytotoxicity of sponges extractswas determined against T47D (breast) cancer cell lines. Results showed that the spatialproduction of aaptamine and isoaaptamine did not correlate with the quality of their surroundinghabitat, despite nitrite and nitrate levels significantly affected the bioactivity of crude extracts.

Abstract

Rumput laut selain sebagai penghasil agar untuk makanan juga dapat menghasilkan agarosa dan agar mikrobiologi yang memiliki nilai ekonomi lebih tinggi. Selama ini di Indonesia agar telah digunakan secara luas dalam industri pangan namun belum banyak dimanfaatkan dalam bidang bioteknologi. Seiring dengan perkembangan penelitian di bidang bioteknologi, permintaan pasar internasional untuk agar mikrobiologi terus meningkat. Bahan baku yang cukup tersedia dan tumbuh tersebar di wilayah perairan Indonesia sangat potensial dalam mendukung produksi agarosa dan agar mikrobiologi.

Abstract

Sponges are simple multicellular animals that produced many pharmaceutical secondary metabolites. Some sponge-associated bacteria are proven to produce the same metabolites as their host, giving an opportunity to mass produce the potential metabolites. The aim of this research was to analyze the diversity of sponge-associated bacteria and to identify  the host sponge. Samples were collected from Seribu Islands National Park. Partial identification of sponges were conducted by molecular technique with the mitochondrial cytochrome oxidase subunit 1 (CO1) as the target area. The diversity of sponge-associated bacteria was determined by Terminal Restriction Fragment Length Polymorphism (T-RFLP) method. Result showed that sponges PS-17-12 has similarity with Petrosia sp., while PS-26-12 and PS-38-12 has similarity with Xestospongia muta. From the 3 sponge samples, 85 species of bacteria was obtained which can be classified into 9 phylums and 1 uncultured bacteria/environment sample. Some of  the sponge-associated bacteria identified were known as a potential producer of metabolites with antibiotic activity.

Abstract

The processing of fishery product is a preservation way to maintain its shelf life. The shelf life offishery product is very crucial, since it is an important source of animal protein which is easilydegraded by microbial activity and enzymatic reaction. Furthermore, fish also contains highunsaturated fatty acid which is easy to oxidize and produce rancid odor. The shelf life prediction offishery product is usually studied using conventional(ESS) and accelerated method (ASLT) Arheniusmodel. The conventional method predicts the shelf life of food product at the normal condition andobserve the parameter of quality degradation until the expired quality is reached. ASLT methodArhenius model predicts the shelf life of food product with accelerate the quality degradationbecause of effect temperature. The conventional method can be applied for wet and semi-wetproducts, such as fish fillet and fish burger, where as Arhenius model can be applied for wet, semiwet and dry products, such as frozen shrimp and dendeng fish.

Abstract

Thermo stability is among of the vital enzyme characteristics for industrial application. Brevibacillus thermoruber LII was obtained as a potential isolate from the previous researchwhich screened the potential thermostable protease producing bacteria from Indonesian hotspring.The newly thermostable protease produced by thermophilic Brevibacillus thermoruber LII hadbeen purified and characterized. It was predicted that the pure enzyme obtained from Brevibacillusthermoruber LII was homo hexameric, having molecular weight of 36 kDa unit protein and itsnative was 215 kDa. In addition, it was also a neutral metalo serine protease according tobiochemical tests that it was totaly inhibited by PMSF (Phenylmethanesulfonyl fluoride) and EDTA(Ethylenediaminetetraacetic acid). It showed optimum activity at pH of 8 and active in acidic buffer(up to pH of 4). All of metal ion in the form of chloride salt (2.5 mM) which were tested on theenzyme enhanced the enzyme activity but Li2+. Ca2+ion increased the activity and the stability ofenzyme against thermal. The enzyme also showed the stability against solvent. The protease LIIhad optimum temperature at 60oC without CaCl 2and 80 – 85oC with addition of 2.5 mM CaCl 2. TheK Mand V maxvalues for the purified protease LII were 27.2 mg/ml or 0.362 – 0.272 M for substrateHammersteinCasein (MM 75–100 kDa) and 261.1 µg/minute/ml, respectively.
