Abstract:
1The antitumour activities of extracts from the Red Sea seaweeds Jania rubens, Sargassum subrepandum, and Ulva lactuca were investigated in an in vivo mice model based on intramuscular injection of Ehrlich ascites tumour cells. In parallel, antioxidant activities were measured. Tumour marker levels, liver biochemical parameters, and hepatic oxidant/antioxidant status were measured to prove the anticancer and antioxidant nature of the algal extracts. Significant decreases in carcinoembryonic antigen (CEA) and α-fetoprotein (AFP) levels, activities of liver enzymes, levels of nitric oxide (NO) and malondialdehyde (MDA), and an increase in total antioxidant capacity (TAC) were recorded in groups treated with the algal extracts. Jania rubens was selected for phytochemical screening of its phytoconstituents. In addition, carotenoids, halides, minerals, lipoidal matters, proteins, and carbohydrates were studied. Furthermore, 7-oxo-cholest-5(6)-en-3-ol () and cholesterol (2) were isolated from the dichloromethane fraction.

Abstract:
The dominant intertidal algal species from Tarifa Island, Strait of Gibraltar, together with the associated peracarid crustacean community, were studied over a two-year period (December 2005–December 2007). Gelidium corneum and Gymnogongrus patens were dominant at the lower levels, close to the subtidal. Valonia utricularis, Osmundea pinnatifida, a turf of Caulacanthus ustulatus and Gelidium spp., Corallina elongata and Jania rubens were distributed in intermediate levels, while Ulva rigida, Chaetomorpha aerea and Fucus spiralis were collected from upper levels. The main intertidal seaweeds of Tarifa Island showed a perennial behaviour, but maximum values of biomass were registered during late spring and beginning of summer for most of species while the highest seawater temperatures were measured in late summer and beginning of autumn. Corallina elongata and Jania rubens, the dominant species which shared a niche at platforms of intermediate levels, showed an opposite behaviour, probably to avoid competence: C. elongata showed higher biomass in April–June and lower values in August–October–December, while biomass of J. rubens was higher in December–February and lower in April–August. Associated crustaceans, including mainly amphipods (gammarids and caprellids) were also present throughout the whole year with similar seasonality to seaweeds. However, crustacean density in the intertidal was not only influenced by distribution of algae as substrate, but also by external factors, such as hydrodynamism, oxygen, weather conditions, competition or predation. The present study constitutes the first baseline study dealing with seasonal fluctuations of algae and associated crustaceans in a protected area of the Strait of Gibraltar, an important biogeographical zone between Europe and Africa and the Mediterranean and Atlantic.

Abstract:
Les ressources naturelles de Jania rubens, une algue calcaire benthique, sont insuffisantes pour leur utilisation à des fins industrielles. Des microthalles axéniques de cette Corallinacée sont utilisés pour déterminer les conditions optimales de production de biomasse. En cultures non agitées, les vitesses de croissance des microthalles axéniques sont de l'ordre de 4 mm par mois, contre 2 mm en milieu naturel. Une réduction du rapport Ca++/Mg++ du milieu ASP12 permet d’optimiser la régénération post-fragmentation et le rendement de production enzymatique de protoplastes. Une incubation à Ca++/Mg++ de 0,05 conduit à une décalcification partielle des thalles sans perte de viabilité. Nous montrons que les fragments de J. Rubens sont cultivables en suspension dans des photobioréacteurs sous agitation mécanique et/ou par bullage d'air. Les expérimentations en réacteurs à recyclage interne de biomasse établissent les relations entre intensité des flux lumineux, variations de l'alcalinité du milieu et valeurs des biomasses sèches finales (> 6 g. L-1). L'analyse des cinétiques de variations d'alcalinité montre qu'il existe un équilibre dynamique entre la libération de carbonate par la biomasse en suspension et la production photosynthétique de biomasse. Ceci permet de définir des seuils critiques, qui sont utilisés pour mettre en place un procédé de production de microthalles de J. Rubens en photobioréacteurs de 60 L et 300 L avec une alimentation de type fed-batch en bicarbonate et calcium. Les valeurs maximales de biomasse sèche et de productivité sont respectivement de 1,75 g. L-1et 0,1 g. L-1. J-1. Les données sont analysées sur le principe d’un fed-batch à volume constant
Natural resources of the benthic alga, Jania rubens, are not enough for industrial applications. Axenic microthalli are used to determine the optimal conditions for biomass production in closed photobioreactors. In unstirred cultures, the growth rate of axenic cultures are about 4 mm per month, against 2 mm per month in the nature. The decrease of the ratio Ca++/Mg++ in the ASP12 medium improve the regeneration of algal fragments and the protoplasts yield obtained by enzymatic digestion. When Ca++/Mg++ ratio is adjusted to 0. 05, the thalli are viable but partially decalcified. We show that Jania rubens can be cultivated as free microplantlets in mini-photobioreactors with mechanical stirring and/or air bubbling. The experimentations with biomass recycling reactors determine the relations between the light intensity, the alkalinity changes of the culture medium and the final biomass concentrations (> 6 g. L-1 DW). The analysis of the kinetics of alkalinity variations and the photosynthetic activities shows that there is a dynamic equilibrium between the processes of carbonatation and de-carbonatation in stirred cultures. As a result, critical thresholds are identified and used to improve the fed-batch production of J. Rubens microthalli in 60 L and 300 L photobioreactors. Maximal biomass and productivities are respectively 1. 75 g DW. L-1 and 0. 1 g DW. L-1. J-1. The data are analysed according the principle of a constant volume fed-batch culture
