The Need of Biofilter for Ammonia Removal in Recirculating Aquaculture System
Harwanto, Dicky ; Jo, Jae-Yoon ;
Journal of Marine Bioscience and Biotechnology, volume 4, issue 1, 2010, Pages 1~5
With the world's population increase, demands of fish production increased rapidly. Because of the demand increase, methods of aquaculture also become more intense. With the increasing intensity of aquaculture, more metabolites in the system are accumulated. The metabolites accumulated in the system turn to the causatives of water quality deterioration and become limiting factors for fish growth. Due to the toxicity of ammonia, ammonia removal is needed in aquaculture system. Biofilters, often referred as biological filter or nitrification filter are commonly used in recirculating aquaculture system to remove ammonia and convert it to nitrite, and then to nitrate.

Indonesia is well-known as biggest producer of seaweed especially for Eucheuma and Gracilaria and also has huge potential resources and capability to develop seaweed cultivation and product. There are several provinces which have potential resources and have been contributing on seaweed production. The next challenge about seaweed production is using integrated system on brackishwater and marine aquaculture. Furthermore, about 2,000,000 ton of potential seaweed production is not explored yet. This article also tries to figure out some related aspects which are technical, economical and forecasting aspect. There is a disease which named "ice-ice" is one of the main problem and giving a new challenge in developing of problem solving for seaweed cultivation method. Economical parameters are also main important key to find out the feasibility of seaweed cultivation industry. In addition, the seaweed cultivation and production in Indonesia also have potential performance on biofuel resources as a part for solving the world problem on energy demand.

The genus Porphyra, consisting of 133 species includes several economically valuable species (i.e. P. yezoensis, P. tenera, P. pseudolinearis etc.). They are predominantly consumed and cultivated in East Asian countries such as Japan, Korea and China, and they are regarded as a big commercial market today. In addition to the industrial importance, P. yezoensis is currently regarded as a feasible candidate for a model plant in marine biotechnology, therefore there are a wide range of studies being undertaken: strain-preservation, development of mutant strains and genetic analysis and exhaustive molecular analysis including EST and macro/micro array. Focusing on the activities of our research group, current situation and future perspectives in marine biotechnological studies using P. yezoensis will be discussed in this mini review.

Seaweed has been consumed especially in the Asia since centuries ago as a vegetable (Matsukawa, 1997; Burtin, 2000; Raghavendran 2003). Seaweed has many valuable nutrients i.e. as a mineral resources, vitamin, and non-caloric fiber, also has potential antioxidant resources. Such of nutrition consists in the Seaweed is Chlorophyll, Carotene, Fucoxantine, Luteen and Zeaxantine, Polysaccharide and Diet Fiber, Mineral, Protein and Amino Acid, Fat and Fatty Acid, Vitamin, Polifenol, also Methanol. The benefits of some nutrition content on seaweed are as an antioxidant, slimmer agent, anti-diabetes, healthy for heart, eyes health, Iodium source, and some kind of vitamins functions. As a conclusion, developing research about seaweed we believe it would be a part of medicine material and food processing, also cosmetic industrial.

Species Kappaphycus alvarezii (Doty) Doty, Kappaphycus striatum (Schmitz.) Doty and Eucheuma denticulatum (N. L. Burman) Collins et Harvey, which was brought to Vietnam from Japan in 1993 and Coco island, Martan Sea, Cebu, Philippines in 2005 have been cultivated in the different coasts of South Central Vietnam. Their growth rates and physical properties of carrageenan, then, were analyzed. The obtained results showed that the growth rate of E. denticulatum and K. striatum strains is higher than those of K. alvarezii. Species of K. striatum could grow over wide range of temperature and tolerate more strongly to high temperature compared with K. alvarezii, but their content and gel strength of kappa-carrageenan were almost the same and high. For purpose of the Kappahycus cultivation farms with stable and high production all year round (especially in the seawaters of shallow, semi-closed Lagoons where the water movement is not good and with high temperature in the hot season), mixed cropping of K. alvarezii and K. striatum as seeds stock during different cropping seasons was established. Our results suggested that K. alvarezii and K. striatum could be grown in the cool season (from Oct. to next March) with the same and high content and gel strength of kappa - carrageenan, but in the hot season need to chose K. striatum for cultivation only (from Apr. to Sept.).

The primary function of the skin is to protect the body from the unwanted environmental influences. The outermost layer of the skin is stratum corneum which consists of corneocytes surrounded by lipid regions. Ceramides covalently bound to keratinocytes are essential for the barrier function of the skin, which can be disturbed in the disease, like xerosis. Xerosis is an abnormal dryness of the skin which reduced the thickness of stratum corneum and ceramide content decreasing with age. In this study, 36 seaweed extracts have been tested for screening of xerosis inhibitory agent by in vitro HaCaT keratinocyte assay. Ishige sinicola and Helminthocladia australis induced the significant amount of ceramide-like substance I in HaCaT keratinocyte among the tested seaweed extracts. Sargassum fulvellum, Chondrus ecellatus and Gigartina tenella also induced the ceramide-like substance I whereas Helminthocladia australis and Pachymeniopsis elliptica induced the ceramide-like II from HaCaT keratinocyte.
