BACTERIOLOGICAL DATA - UNIVERSITY OF MARSEILLE
Entry ID: COMB01


[ Update this Record ]

Summary
Abstract: ENGLISH

Data on bacterial biomass, bacterial processes and adaptation to in situ
conditions of ocean; data on quantity and quality of organic matter.

Water samples were collected from Niskin bottles. Samples came from the
Mediterranean, Antarctica, North Atlantic, and from samples collected during
the multidisciplinary national programs of INSU (Institut National des Sciences
de l'Univers) and the european CORDIS/MAST program (Community Research and
Development Information Service/Marine Science and Technology Program).
Measurements include: bacterial degradation in organic matter, bacterial
growth, and production rate of methane. Role of bacteria in C, N, and P
fluxes. Study of lipid markers. Bacteria adaptation to extreme conditions in
the maritime environment. Cellular response to different stress conditions.

FRANCAIS

Prelevements d'eau (bouteilles Niskin preleveur sans decompression), dans les
sediments (carottier multitubes), de particules (pompes in situ). Echantillons
en provenance de la Mediterrannee (Ouest et Est - y compris les fosses
anoxiques), de l'Antarctique,de l'Atlantique Nord-Est et collectes lors de
campagnes multidisciplinaires des programmes nationaux INSU et europeens
(MAST). Mesures de la vitesse et rendement degradation bacterienne des
principaux composants de la matiere organique dissoute et particulaire (vitesse
hydrolyse des macromolecules, vitesse mineralisation des monomeres, et
mineralisation des composes de faible poids moleculaire), calcul des rendements
de croissance des bacteries. Activites methanogenes et sulfatoreductrices.
Mesures de vitesse de production biomasse bacterienne, de methane (degradation
anaerobie). Recherche de marqueurs biochimiques (lipides) des activites
bacteriennes. Role des bacteries dans le flux de Carbone, Azote et Phosphore.
Adaptation des bacteries aux conditions extremes du milieu marin: oligotrophie,
barophilie, rayonnement UV. Reponse cellulaire aux differents stress.
