  • The objective of this study is to investigate the waste recycling possibility, practicability, economic efficiency and acid gas sorbent use of the hard-shelled mussel. This study is to investigate the hydration/calcination reaction and fixed bed reactor. The physical-chemical characteristics of the hard-shelled mussel were analyzed by ICP SEM-EDX, BET and pore volume. Thus, the results could be summarized as follows; Hard-shelled mussel can be used as iron-manufacture and chemical sorbents considering more than 53.7% of the mussel is lime content. The SO$_2$removal efficiency of the hard-shelled mussel after calcined hydration increased thirty times as a result of the higher pore size, specific surface area and pore volume. Also, the CaO content, pore volume, pore size distribution and specific surface area greatly influenced the SO$_2$ and NOx removal reactivity. The optimum particle diameter average of hard-shelled mussel was $\pm$100 mesh, which was applied to the sorbent on the medium/small scale waste incinerator and flue gas desulfurization processes.

  • White breads containing Korean blue mussel (Mytilus edulis) powder were prepared and characterized. WB (white bread without blue mussel) and four different MBs (white breads containing blue mussel; number in front of MB means added % of blue mussel powder per wheat flour) were prepared by the straight dough method. With addition of blue mussel to bread, lightness decreased, whereas redness and yellowness increased. Addition of blue mussel did not significantly affect specific volumes of breads. DPPH and ABTS radical scavenging activities significantly increased with increasing blue mussel content. Addition of blue mussel to breads also increased alcohol dehydrogenase and acetaldehyde dehydrogenase activities. In the sensory test, 1MB acquired relatively high points for taste, flavor, texture, and preference. The results indicate that blue mussel can be applied to white bread to improve physiological functions without reduction of physicochemical characteristics.

  • The physiological activities of cultivated Korean blue mussel (Mytilus edulis) and New Zealand green-lipped mussel (Perna canaliculus) were analyzed and compared. Both hot water extracts of blue mussel flesh (BMF) and green-lipped mussel flesh (GMF) showed increased activities of alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH). BMF showed increased ADH and slightly decreased ALDH activities compared to GMF. 1,1-Diphenyl-2-picrylhydrazyl radical scavenging activity of BMF was higher than that of GMF at the same concentration. BMF and GMF showed similar inhibitory activity against angiotensin converting enzyme at a concentration of 30 mg/mL. These results suggest that cultivated Korean blue mussel has similar physiological activity with New Zealand green-lipped mussel.

  • Mussel adhesive protein (MAP) was extracted from Korean Mytilus edulis and then partially purified using Sephacryl S-300 gel permeation chromatography and reversed-phase high performance liquid chromatography. As an indicator of adhesiveness, is 3,4-dihydroxyphenylalanine (DOPA) content was determined. Its DOPA/protein ratio of 0.19 was higher than those of other reports, indicating a good adhesive. The partially purified MAP was confirmed by acid-urea polyacrylamide gel electrophoresis using cetylpiridinium bromide as a cationic detergent. Sea mussel hydrolysates were prepared using three commercial proteases to provide value-added functional materials and their angiotensin converting enzyme (ACE) inhibitory activities were determined. Among hydrolysates of sea mussel, Protamex was the best and further purification would improved ACE inhibitory activity.

  • For the development of a hangover soup containing blue mussel, 11 kinds of hot water extracts were prepared - A (mistletoe); B (shepherd's purse); C (arrowroot); D (bean sprout); E (oriental raisin); F (blue mussel); G (blue mussel and mistletoe); H (blue mussel and shepherd's purse); I (blue mussel and arrowroot); J (blue mussel and bean sprout); and K (blue mussel and oriental raisin). Extract C showed the highest effect for increasing the activities of alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH); however, the addition of blue mussel did not provide a synergy effect on extract C. Other than the arrowroot-containing extracts (C and I), extract H showed relatively higher ADH ($237.4{\pm}1.7%$) and ALDH ($136.5{\pm}2.1%$) activities. Moreover, extract H showed the highest DPPH radical scavenging activity ($93.9{\pm}0.1%$) and angiotensin I converting enzyme (ACE) inhibitory activity ($42.7{\pm}1.6%$). The combination of blue mussel with shepherd's purse had a synergic effect on its ADH and ACE inhibitory activities.

  • Mussel byssal protein has strong adhesive capability even in wet surface. It has been reported that nine proteins in marine blue mussel, often referred to a representative mussel, contribute to form mussel byssal threads and plaques. DOPA containing two hydroxy groups called cathecol is recognized that it plays a major role in adhesion as well as cohesion process within byssal structure. In this paper, adhesion and cohesion mechanisms were introduced and evaluated by supportive literature published during last decade. Diverse applications of cathecol chemicals were also examined in terms of innovative adhesive, bioadhesive and challenging material for tissue engineering. It is noticeable that reconsideration of mussel proteins could provide the various opportunities as biomaterials.

  • The adhesive performance of marine mussel extract was compared with that of the commercial medical adhesives for fastening biotissue (SIS) bandages. Joints bonded with mussel extract showed stronger strength than those bonded with other commercial adhesives. The bonding strength was much improved when the moisture in the Joint was reduced using superporous hydrogel regardless of curing time under humid condition ($37^{\circ}C$ and 91% relative humidity). Water inflow into the SIS joint seemed to degrade the performance of mussel extracts adhesive especially for the joints of short period of curing time. The strength of SIS joints coated with surgical sealant was well maintained after being exposed to water inflow.

  • The fauna associated with mussel (Mytilus galloprovincialis) beds and vertical distribution of macrobenthos were studied on the Goijeong rocky shore in Jinhae Bay, Korea. Sampling was conducted seasonally using a quadrate from January to October, 1998. In the first experiment, to reveal the community structure of macrobenthos in mussel bed, a total of 62 species $(10,690ind./m^2,\;3,802.1\;g/m^2)$ were identified, which included polychaetes $(32\;spp.,\;52.6\%),$ molluscs (16 spp.), crustaceans (10 spp.), and others. The density-dominant species were Pseudopolydora antennata, Nereis heterocirrata, Littorina brevicula and Balanus kondakovi. And the density of associated fauna was correlated with that of mussel (r=0.951, p=0.049). In the second experiment, to reveal the vertical distribution of macrobenthos on the rocky shore, ANOVA showed highly significant differences between the density of top 5 dominant species (Chthamalus challengeri, Littorina brevicula, Balanus kondakovi, Septifer virgatus and Granulilittorina exigua) and tidal levels (P=0.000). Vertical distribution of macrobnethos was characterized by Ghthamalus belt and Balanus-Septifer belt in the mussel bed.

  • This study was designed as a part of efforts to investigate the biochemical pollutant markers for diagnosis of marine pollutions by changes in cholinesterase activity of the mussel (Mytilus coruscus) in South Sea of Korea. Acetylcholinesterase (AChE) activities in muscle of cultured mussels in South Sea were remarkably lower (20∼41%, respectively) than those of wild mussel in Pohang(control) of East Sea. Acetylcholine (Ach) activities in muscle of cultured mussels in South Sea were remarkably lower (15∼30%, respectively) than those of wild mussel in Pohang of East Sea. Monoamineoxidase (MAO-B) activities in muscle of cultured mussels in South Sea were significantly 2∼19% higher than those of wild mussel in Pohang of East Sea. It suggests that AChE, ACh and MAO-B activities in muscle of cultured mussels of South Sea may be used as the most effective mean in a biochemical markers for early warning of environmental damages caused by organophosphorus pesticides.

  • This study have conducted to calibrate the productivities on the mussel (Mytilus galloprovincialis) cultures in Jinhae Bay. Annual water temperature, salinity and dissolved oxygen have varied to 7.2-$25.9^{\circ}C$, 32.9-34.0 psu, 7.9-8.7 mg/l, respectively. In April, the smallest size of spat, 3.3 mm in shell length, have recruited, and 82.5 mm have recorded to the maximum. In summer, variations of growing up between individuals showed both shell length and weights at same cohort. Annual production at 2 m, 5 m, 8 m depth calculated to 10.91, 10.85 and 9.19 gWWt/ind./yr, respectively. Mussel cultivated in the upper part of the water column (two meter depth) were significantly longer and heavier than those in lower part (eight meter depth). After the recruitment, monthly production showed gradual increment at all positions during summer. As results, annual production of mussel cultivated seemed to be controlled by conditions of growing up in summer. Based on the productivities calculated to this study, the total annual production of the mussel cultivated in Jinhae Bay have estimated about 196 ton/ha/yr.
