    Etude d'une population naturelle de la rhodophycée Cystoclonium purpureum. (2016)
    Details
    Publication Date: 2021-05-19
    Description: L'etude d'une population naturelle de l'algue rouge Cystoclonium purpureum a montre que les thalles debutent leur croissonce au printemps pour atteindre leur developpement maximum ent ete. En automne, les algues commencent a disparaitre progressivement. En effet, le poids maximum des thalles est atteint en Juillet (No. 40g). Pendant la meme periode, la longueur des algues atteint son maximum (25,3 cm). Quand au diametre de la fronde, son evolution au cours du temps n'est pas claire. La biomass de Cystoclonium atteint egalement son apogee en Juillet (environ 35 g de MS/m2)
    Description: Study of Cystoclonium purpureum showed that thalli begin to grow in spring and reach highest developement in summer. In autumn, these algae disappear gradually. In fact, the maximum weight is obtained in July (No.40g). In the same period, algae length reach its maximum value, too (25,3cm). While frond diameter evolution isn't clear. Biomass of Cystoclonium reach its highest value in July, too (about 35g DM/m super(2))

    Culture du phytoplancton en petits volumes. (2016)
    Details
    Publication Date: 2021-05-19
    Description: Dans ce travail, realise a l'ecloserie de l'INSTOP a Ghar El Melh, on se propose d'exposer les resultats des cultures du phytoplancton dans une salle climatisee en petits volumes. Par opposition aux cultures en grandes volumes soumises aux aleas climatiques, cette technique permet la maitrise des parametres physico-chimiques (lumiere, temperature, sels minerauxa) et l'obtention de hautes densites algales dans un laps de temps assez court. (DBO)
    Description: In this work, conducted in the INSTOP hatchery at Ghar El Melh, the results are given of the culture of small volumes of phytoplankton in an air-conditioned room. As opposed to culture of large volumes, subject to climatic variations, this technique allows the control of physico-chemical parameters (light, temperature, mineral salts) and the production of high algal densities in a short lapse of time.

    La rhodophycée Gracilaria verrucosa (Hudson) Papenfuss, du lac de Bizerte (Tunisie): variations mensuelles de la biomasse, du rendement et de la qualité de l'agar. (2016)
    Details
    Publication Date: 2021-05-19
    Description: During the year of 1999, the red seaweed Gracilaria verrucosa (Hudson) Papenfuss (Rhodophyta, Gracilariales, Gracilariaceae), has been followed monthly in Bizerte lake (in the north of Tunisia). The parameters studied are: biomass, agar-yield, gel strength, gelling and melting temperatures. The results showed that the highest average of wet biomass is recorded in June (2500 g/m super(2)) and the lowest is obtained in October (130 g/m super(2)). The highest agar-yield is obtained in April (37,92 %) ; while the lowest is recorded in September (10,67 %). High and low gel strengths are obtained in May (410g /cm super(2)) and in December (125 g :cm super(2)), respectively. Gelling temperature varies between 31 degree C and 44~ 'C, while melting temperature varies between 79 degree C and 100 degree C

    Evaluation des potentialités quantitatives naturelles des Gracilaires (algues rouges) du lac Nord de Tunis. (2016)
    Details
    Publication Date: 2021-05-19
    Description: L’estimation de la biomasse de la macroalgue Gracilaria dans le lac nord de Tunis a été réalisée au cours de Juin-Juillet 1996 à partir de 38 stations d’échantillonnage couvrant tous les types de recouvrement de l’espèce. Il en ressort que la biomasse en poids humide est de 191 g/m2 (28 g/m2 en poids sec) et engendre un potentiel total estimé à 508 tonnes, soit 74 tonnes en poids sec (la matière sèche représentant en moyenne 14,5 % de la matière humide). Eu égard à la quantité de Gracilaria disponible à l’état naturel, la valorisation de cette espèce au niveau de ce site pourrait demander le recours à la phycoculture.
    Description: The red seaweed Gracilaria biomass in the Tunis north lake (Tunisia) was estimated between June and July 1996 with reference to different stations. This biomass represent 191 g/m super(2) (wet weight) and 28 g/m super(2) (dry weight). so the total quantity is estimated to 508 t in wet and 74 in dry (the average of dry material represent in general 14,5 % of the humid materiel). Because of its low natural total production, the development of Gracilaria seaweed in this site need culture processing.

    Description: Ocean Sampling Day was initiated by the EU-funded Micro B3 (Marine Microbial Biodiversity, Bioinformatics, Biotechnology) project to obtain a snapshot of the marine microbial biodiversity and function of the world’s oceans. It is a simultaneous global mega-sequencing campaign aiming to generate the largest standardized microbial data set in a single day. This will be achievable only through the coordinated efforts of an Ocean Sampling Day Consortium, supportive partnerships and networks between sites. This commentary outlines the establishment, function and aims of the Consortium and describes our vision for a sustainable study of marine microbial communities and their embedded functional traits.
    Description: This work was supported by the Micro B3 project, which is funded from the European Union’s Seventh Framework Programme (FP7; Joint Call OCEAN.2011‐2: Marine microbial diversity – new insights into marine ecosystems functioning and its biotechnological potential) under the grant agreement no 287589.
