Codium fragile is commercially farmed in Korea by natural blooming zygote attachment. Experiments found optimum conditions for artificial seed production and nursery culture of C. fragile by asexual reproduction. Isolated utricles and medullary filaments were regenerated to erect thalli using both indoor and outdoor culture experiments. Under the indoor culture conditions, irradiance was an important factor to control the development of erect thalli. Formation of erect thallus from the isolated medullary filaments in the indoor culture was induced after 30 days under $20^{\circ}C$ and $60{\mu}mol/m^2/sec$. The detachment of isolated utricles and medullary filaments from the substrates of seed strings was reduced by exposure to the air during 2 hrs before the indoor culture of seed strings. The maximum growth and development of erect thalli in the nursery culture was induced at a water depth of 0.5 m. Depending on the substrates of the seed strings the growth of erect thalli was not significantly different (p>0.05).

Codium fragile is an edible seaweed in Asian countries that has been used as a thrombolytic, anticoagulant, antioxidant, anti-inflammatory, and immune-stimulatory agent. Ginseng has also been known to maintain immune homeostasis and to regulate the immune system via enhancing resistance to diseases and microorganisms. In this study, anionic macromolecules extracted from C. fragile (CFAM) were orally administered with red ginseng extract (100 mg/kg body weight) to cyclophosphamide-induced immunosuppressed male BALB/c mice to investigate the immune-enhancing cooperative effect of Codium fragile and red ginseng. Our results showed that supplementing CFAM with red ginseng extract significantly increased spleen index, T- and B-cell proliferation, NK cell activity, and splenic lymphocyte immune-associated gene expression compared to those with red ginseng alone, even though a high concentration of CFAM with red ginseng decreased immune biomarkers. These results suggest that CFAM can be used as a co-stimulant to enhance health and immunity in immunosuppressed conditions.

한약재의 원료 및 전세계적 외래종으로 알려져 있는 녹조류 청각(Codium fragile)의 디클로로메탄, 에탄올, 열수 추출물을 대상으로 하여 생쥐에서의 항 염증, 해열, 및 진통 활성을 조사하였다. 청각의 디클로로메탄과 에탄올 추출물은 phorbol 12-myristate 13-acetate로 유도된 생쥐 귀의 부종과 충혈에 대한 염증 증상을 74% 이상의 높은 저해 작용을 보였으며, 이들 추출물은 acetyl salicylic acid와 유사하게 발열증상을 억제하였다. 청각으로부터 주된 항 염증 활성물질은 eicosapentaenoic acid인 것으로 분리되었다. 이러한 결과는 청각이 여러 염증 관련 증상에 대처할 약제로서도 사용되어 질 수 있다는 사실을 뒷받침해 준다.

The Mediterranean Sea is currently facing dramatic changes and threats, including change in native species and accidental introductions. The introduced green alga Codium fragile subsp. fragile (Suringar) Hariot influences diversity and community structure in some parts of the world. This paper documents the distribution of this species in Tunisia and provides a morphological description of C. fragile subsp. fragile in Northern Tunisia. Results confirm the identity of Tunisian specimens as the invasive subspecies C. fragile subsp. fragile. This is the first morphological characterization of this subspecies in Tunisia.

한국산 자생생물 발굴조사의 일환으로, 해양 녹조류 2종, Caulerpa peltata J.V. Lamouroux 및 Codium geppiorum O.C. Schmidt이 채집되었고, 본 종에 대한 형태학적 및 분류학적 관찰이 수행되었다. Caulerpa peltata는 직립지에서 선형의 소지를 방사상으로 낸다는 점에서 속내의 다른 한국산 종과 구분된다. Codium geppiorum은 뭉툭한 정단부의 포낭, 부풀지 않은 가지 정단부 및 인접 가지 사이의 2차적인 유합 흔적인 돌출된 혹에 의해 특징지어진다. 이 2종은 미기록 종으로 여기서 한국 해조상에 처음 보고된다.

Seaweed biomass was estimated using a nondestructive sampling method in the rocky intertidal and subtidal zone in Daejin on the mid-east coast of Korea from August 2006 to April 2008. Seasonal sampling were done at the depth of 0, 1, 5, 10 m using 50 x 50 cm quadrat. A total of 95 species, including 11 chlorophytes, 26 phaeophytes, 57 rhodophytes and one sea grass were identified. Mean biomass was comprised of 1,292 g wet wt m$^{-2}$ and the biomass values varied seasonally from 904 g to 1,945 g. Dominant species in biomass were Sargassum spp. (S. horneri, S. yezoense), Corallina pilulifera, Phyllospadix japonica, Symphyocladia latiuscula, Hizikia fusiformis, Codium arabicum and Chondrus ocellatus at Daejin. The vertical distribution of algae were characterized by Corallina pilulifera, Symphyocladia latiuscula, Sargassum spp. (S. confusum, S. yezoense), Hizikia fusiformis and Grateloupia elliptica at intertidal zone, Sargassum spp. (S. fulvellum, S. horneri, S. yezoense), Phyllospadix japonica, Codium arabicum, Undaria pinnatifida and Corallina pilulifera at 1 m depth, Sargassum spp. (S. horneri, S. micracanthum, S. yezoense), Phyllospadix japonica, Grateloupia elliptica, Gelidium amansii and Codium arabicum at 5 m depth and Phyllospadix japonica, Codium arabicum, Sargassum spp. (S. horneri, S. micracanthum, S. yezoense) and Undaria pinnatifida at 10 m depth.

This study investigated the physicochemical, microbiological, antioxidant, and sensory characteristics of Makgeolli supplemented with 10, 20, and 30% Codium fragile (Cf) during an 8-day fermentation period. The pH and acidity on day 0 were lower in Makgeolli supplemented with Cf (pH 3.55-3.65, acidity 0.26-0.29%) than in the unsupplemented Makgeolli (control) (pH 3.72, acidity 0.23%). The pH and acidity of Cf Makgeolli on day 8 were 3.08-3.12 and 0.67-0.75%, respectively. The sugar content increased steadily until day 4 (8.1-8.5 Brix) and then decreased steadily (6.5-6.8 Brix). The alcohol content increased steadily until day 8 (13.2-14.3%). The pH decreased, acidity increased, and alcohol content increased significantly (all P<0.05), with stepwise increases in fermentation time and Cf concentrations. The lactic acid bacteria counts were 9.28-9.37 log versus 8.18 log in the control. The DPPH (1,1-diphenyl-2-picrylhydrazyl) and ABTS [2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)] radical scavenging activities were higher in Cf Makgeolli (DPPH 74.63-84.64%, ABTS 51.01-64.79%) than in the control (DPPH 30.97%, ABTS 21.21%). Makgeolli supplemented with 10 and 20% Cf had the highest taste, smell, and overall acceptance scores. This study suggests that Makgeolli supplemented with 10 and 20% Cf could be developed due to its good physicochemical and microbiological characteristics, including high antioxidant properties and good consumer acceptance.

This study investigated the antioxidant activity and general and sensory properties of soybean curd supplemented with Codium fragile. The yield of soybean curd containing 0%, 20%, and 40% C. fragile was 113.62, 104.09, and 108.06, respectively. Antioxidant activities and pH were significantly increased (P<0.05) depending on the amount of C. fragile supplemented in soybean curd. Compared to that in additive-free soybean curd (control), the amount of crude ash and protein in soybean curd containing 40% C. fragile was significantly decreased (P<0.05) and increased (P<0.05), respectively. We observed a dose-dependent increase (P<0.05) in the hardness and chewiness of soybean curd concomitant with the amount of C. fragile supplemented. In contrast, we observed no significant difference (P>0.05) in soybean curd's cohesiveness between the groups. As determined by sensory evaluation based on seven-point hedonic scale, soybean curd supplemented with 20% C. fragile received an excellent score (6.55) for color. As the same method, we observed that the flavor and overall acceptability significantly increased (P<0.05) in the C. fragile content increased. Taken together, the antioxidant and sensory assays in our study make a compelling case for the practical development of soybean curd supplemented with C. fragile owing to its good antioxidant activities, general properties, and consumer acceptance.
