Full textThe invasive algae Grateloupia turuturu and Sargassum muticum were chosen as models of this study. The aims of this work were i) to understand the population biology of G. Turuturu and S. Muticum and their adaptation strategies in novel habitats, ii) to determinate if their adaptation strategies were related to the development of a chemical defence based on antifouling compounds synthesis, iii) to characterize metabolites involved in this chemical defence and produced by the two algae. Lien, a pluridisciplinary study was carried out including an ecological survey of the two invasive algae at three field sites selected along the coast of French Brittany, a screening of the antifouling activity of extracts from G. Turuturu and £ muticum, and a chemical work in order to isolate and identify compounds present in the active extracts. Results allow us to better understand the population biology of G. Turuturu and S. Muticum and to higlight the impact of environmental parameters on variables studied in both species. Antifouling tests highlighted the dichloromethane extract from G. Turuturu and the chloroform extract from S. Muticum as the most actives. The chemical work led to the isolation of cholesteryl formate from G. Turuturu and to the identification of hydrocarbons, free fatty acids and galactoglycerolipids from S. Muticum. All these compounds showed antifouling activities against several strains of bacteria implicated in microfouling

Full textThe present study is aimed at providing (i) accurate data on the relationships between phytoplankton and bacteria responses to varying loading levels of nutrients such as nitrogen, phosphorus and organic matter, and (ii) insight into the denitrification process from in situ experiments. The low developpment of phytoplankton was unlikely to be accounted for by the prevailing hydrodynamic, trophic and light conditions, all indeed favouring its growth, therefore competion processes were thougth to exist between diverse plant standing stocks. Regarding the bacterial compartment, a significant increase in biomass and activity was also manifest downstream of Angoulême's sewage effluent discharges. Bacteria associated to such urban effluents were characterized by both physiological features (high ratio, i. E. 20, for leucine to thymidine incorporation rates) and morphological features (high biovolume, i. E. Higher 0. 2 [mu]m3) far distinct from those displayed by autochthonous bacteria (i. E. Mean cellular volume fo roughly 0,15 [mu]m3 and low leucine : thymidine ratio of approx. 10). The present investigation, however, gave no evidence of signifiant relations betweeen phytoplanktonic and bacterial communities. Indeed, allochthonous supplies of organic matter were merely shown to meet bacterial carbon requirements sufficiently so that no further substantial supply by primary production (in terms of excretion or algal exudates) was needed to enable bacteria to develop. The denitrification process resulting in nitrogen losses as nitrogen gas (NH2), it was clearly pointed out that if such a denitrification process did not occur in the whole water column, its rate at the water-sediment interface might be considered as constant and independant from variations in temperature, nitrate contents and dissolved oxygen levels at the interface. Then, the annual mean rate of denitrification in the River Charente levelled off at 682 mgNO3/m2/j bejond any marked environmental influence

Full textThe most important primary producer groups of the coastal zones are suspended phytoplankton cells (Pannard et al, 2008) and microphytobenthos (MPB) (Woelfel et al., 2010). In these regions, phytoplankton and benthic microalgae are both recognized as being principal components of the diet for economically important suspension-feeding fauna (Gillespie et al., 2000). However, although phytoplankton has been vastly documented, MPB is often understudied.In sufficient light for photosynthesis they can inhabit the top few centimeters of the substrate layers (mud or sand) of marine sediment (Charpy and Charpy-Roubaud 1990, MacIntyre et al. 1996, MacIntyre and Cullen 1996) and play an important role as a food source for higher trophic levels (Revsbech et al. 1981, Sorokin 1991, Charpy and Charpy-Roubaud 1990 ). Benthic microalgal biomass mostly follows a similar distribution to the total organic matter content of surficial sediments indicating that sediment geochemical processes such as nutrient release from the breakdown of organic matter may be important in determining the distribution of MPB (Light, 1998). However, on the other hand, though not proportional with the MPB biomass, benthic production can even surpass the pelagic contribution (Underwood and kromkamp, 1999). With their ability of high primary production benthic microalgal communities can profoundly influence the flux, transformation and turnover of carbon and nutrients in coastal areas. Benthic primary producers contribute to the availability of energy and matter for benthic and pelagic food webs and define benthic and pelagic energy budgets, which affect the chemistry at the sediment-water interface, and regulate sediment stability. The shallow waters, where MPB thrives, allow a more direct interaction between pelagic and benthic processes keeping the benthos much less susceptible to physical and biochemical disturbances such as evaporation, eutrophication, and wind-forcing (Molen, 2011). Because attached microalgae can avoid advective processes and adapt to changes in light availability at short time scales, their importance is particularly enhanced (Phinney, 2004). As a result of the impact that MPB carries in a coastal ecosystem, along with the study of the functional role of MPB, investigations on their diversity have also gained some importance in the last two decades (Sundbaeck & Joensson, 1988; Blanchard, 1990; Montagna et al., 1995). Like phytoplankton, MPB communities can also act as sensitive indicators of water quality as the taxonomic composition of MPB assemblages can vary as per different nutrient levels (Lange-Bertalot, 1979; Kann, 1986). However, although the importance of MPB has been emphasized on intertidal zones (Pinckney & Zingmark, 1993; Colijn & De Jonge, 1984; Herman et al., 2000), the subtidal zones have generally been ignored till yet on this regard and as a result of which not much is known about the MPB dynamics in the subtidal zones. The subtidal zone of Bay of Brest was chosen for this study because there had been comprehensive input of nitrates to the zone in the past century .This zone has being amazingly resistant to eutrophication for quite some time, although silicate and nitrate ratio got down during the past 20 years. Research has been done previously on the spatial distribution of MPB in the zone in terms of primary productivity and biomass, but in order to achieve a more holistic view of these important photoautotrophs, a temporal study is necessary as well. The objectives of this work have been to characterize the temporal distribution of MPB in terms of biomass, productivity and biodiversity in the subtidal zone of Bay of Brest on a monthly scale, assess a comparative reasoning between MPB and the phytoplankton of the overlying water column complying on the same factors and draw an understanding on the significance of seasonal fluctuations of MPB in the overall seasonal distribution of photoautotrophs.

Full textParadoxalement, les algues microscopiques et les cyanobactéries constituant ces biofilms sont peu connues en France. La première approche de ce projet a donc consisté à prélever des fractions de revêtements de façade colonisés afin d'identifier les micro-organismes s'y développant. 22 espèces d'algues et 25 espèces de cyanobactéries ont ainsi été observées dans les 71 prélèvements analysés, les algues étant dominantes sur tous types de matériaux.
Les facteurs favorisant l'implantation et le développement de ces micro-organismes ont ensuite été étudiés. Un traitement statistique des données environnementales recueillies lors de la campagne d'échantillonnage a ainsi mis en évidence l'importance des facteurs climatiques liés à l'humidité, des facteurs permettant la dissémination des spores, tels que le vent ou la proximité de végétation, ainsi que l'importance de la nature du support colonisé. Cette dernière observation a pu être approfondie grâce à l'utilisation d'un banc d'essai permettant l'évaluation simultanée de différents matériaux quant à leur colonisation par des algues et des cyanobactéries isolées en façade au cours de cette étude. Ces essais ont montré que des facteurs tels que la porosité, la rugosité et le pH de surface des matériaux influent sur la colonisation par ces micro-organismes.
En parallèle, afin d'envisager le développement de matériaux défavorisant l'accroche des micro-organismes, les mécanismes d'adhésion d'une sélection d'algues sur des surfaces modèles ont été étudiés à l'aide d'une cellule à flux laminaire. Les surfaces hydrophiles ont provoqué le plus faible taux d'adhésion. L'exploitation de ces résultats a également mis en évidence l'initiation d'interactions hydrophobes et électrostatiques lors du processus d'adhésion.
Finalement, les polymères extracellulaires produits par une sélection de micro-organismes isolés en façade ont été analysés. Ils ont ainsi montré être de nature polysaccharidique, anionique et plus ou moins hydrophobe selon les souches les sécrétant. L'adsorption d'un polymère d'une souche de Klebsormidium flaccidum, algue verte dominante en façades en France, a été plus importante et plus forte sur des surfaces hydrophobes que sur des surfaces hydrophiles. En outre, la dégradation enzymatique des polymères de cette même souche tend à diminuer l'adhésion sur surface hydrophobe. Ces observations confirment donc l'hypothèse d'une intervention des polymères extracellulaires dans l'étape de contact du micro-organisme avec une surface, puis lors de l'étape de consolidation de cette adhésion, par le biais d'interactions hydrophobes et sans doute électrostatiques.
