Squalen publishes original and innovative research to provide readers with the latest research, knowledge, emerging technologies, postharvest, processing and preservation, food safety and environment, biotechnology and bio-discovery of marine and fisheries. The key focus of the research should be on marine and fishery and the manuscript should include a fundamental discussion of the research findings and their significance. Manuscripts that simply report data without providing a detailed interpretation of the results are unlikely to be accepted for publication in the journal.

Abstract

Since identified having better properties such as solubility in water and bioactivities comparedto its polymer form, chitooligosaccharide has obtained great attention either from researcher andindustries. Wide application of chitooligosaccharides, from pharmaceutical, food and agriculture,is very depending on the deacetylation degree and the size of oligosaccharide. Enzymaticproduction is more dependable in producing specific, safe and environmentally friendlychitooligosaccharide. Chitosanase is one of chitin degrading enzymes group, having importantrole in production of chitooligosaccharide. Shrimp and crustacean waste which are abundant inIndones ia are important raw material for chitin and its deriv ativ e produc ts inc ludingchitooligosacharide and as a source of chitin degrading enzymes including chitosanase. RCMFPPBhas a c ollec tion of potential c hitin degrading mic robes for produc ing func tionalchitooligosaccharides for food, pharmaceutical and biocontrol applications. There is a bigopportunity for Indonesia as chitooligosaccharide producer as we have relatively big amount ofraw material from shrimp and crustacea’s waste, and local enzyme. One of the problem is thelegality of chitooligosaccharide for food and pharmaceutical products has not been available yet.Another non food application such as biocontrol can be developed first since this product does notneed strict regulation as for food.

Abstract

Biofuel is one of alternative fossil fuel, in which the raw materials come from biological resources.One of the raw materials for biofuel production is microalgae. Microalgae grows rapidly, does notcompete with food for humans, and needs small areas to cultivate. Utilization of microalgae forbiofuel research nowadays is focusing on biodiesel production, but actually microalgae can beused to produce other biofuels such as bioethanol. The carbohydrate content of the microalgaecan be converted into glucose and fermented into alcohol. Carbohydrate content of the microalgaeis about 5.0–67.9%, which could produce bioethanol up to 38%. A harmony between bioethanoland biodiesel production from microalgae is needed for the optimum utilization of microalgae.Bioethanol production from microalgae can be done using de-oiled microalgae.

Abstract

The combination of seaweed Sargassum sp. and fish waste hydrolysate can be used as anorganic fertilizer, both in liquid or solid forms. The organic fertilizer has a complete macro andmicro nutrients. It contains growth hormone factor such as auxin, cytokinine (zeatin and kinetin)and giberelin. The function of growth hormone factor in plants is to enhance the roots, stems, andleaves expansion, as well as to increase fruit production. To produce liquid organic fertilizer,seaweed has to be hydrolyzed in alkaline condition, meanwhile solid waste of fish has to behydrolyzed in acid condition. The liquid organic fertilizer had protein value of 0.08% or equal to0.012% N, 0.13% P, 1.22% K, 0.06% Ca, 0.17% Mg, 55.04% Fe, 122.75 ppm Mn, 1.95 ppm Cu,24.59 ppm Zn, 13 ppm B, and 18% alginic acid. It had auxin (IAA) of 91.48 ppm, cytokinine of84.71 ppm kinetin and of 70.27 ppm zeatin and giberellin (GA3) of 107.72 ppm.

Abstract

Food infection and intoxication of fish products are common due to consumption of foodexposed by either pathogenic or toxin promoter bacteria. A number of pathogenic bacteria havebeen identified related to fish and seafood such as Vibrio parahaemolyticusand other Vibrios,Escherichia coli, Aeromonas spp., Salmonellaspp., Staphylococcus aureus, Listeriamonocytogenes, Clostridium botulinum, C. perfringens, and Shigellaspp. However, isolationand identification of pathogenic bacteria from fish and seafood are often difficult due to the highnumber of contaminating and indigenous bacteria, while numbers of pathogenic bacteria arerelatively low. In the last 3 decades, several molecular methods have been developed and adoptedas official standard to supplement classical method, such as polymerase chain reaction (PCR)and its applications. Besides its limitation, molecular based identification offers advantages asroutine or screening analytical protocol for pathogenic bacteria in fish and seafood products.

Abstract

This study aimed to explain the feasibility of fingerprint and chemical marker metabolomicanalysis in assessment of coral reefs environments. Based on literature review, both analysismight be implemented on coral reef environment assessment, with their specific strength andweakness. Fingerprint metabolomic is a comprehensive approach in assessing the condition ofcoral reefs bioindicator that is having environmental stresses. It require high technology chemicalinstrumentation and complicated statistical approach in post data analysis. On the other hand,chemical marker metabolomic is more simplified in data analysis and instrumentation, but notcomprehensively assess the metabolite changes of bioindicator that is having environmentalstresses. To apply as high throughput screening in coral reefs assessment, subjectively the chemicalmarker method would be more feasible. One of the potential chemical marker that used iscembranoids, a bioactive compound from soft corals.
