A Long-Term Cultivation of an Anaerobic Methane-Oxidizing Microbial Community from Deep-Sea Methane-Seep Sediment Using a Continuous-Flow Bioreactor
Anaerobic oxidation of methane (AOM) in marine sediments is an important global methane sink, but the physiological characteristics of AOM-associated microorganisms remain poorly understood. Here we report the cultivation of an AOM microbial community from deep-sea methane-seep sediment using a continuous-flow bioreactor with polyurethane sponges, called the down-flow hanging sponge (DHS) biore...
متن کاملFlexible community structure correlates with stable community function in methanogenic bioreactor communities perturbed by glucose.
Methanogenic bioreactor communities were used as model ecosystems to evaluate the relationship between functional stability and community structure. Replicated methanogenic bioreactor communities with two different community structures were established. The effect of a substrate loading shock on population dynamics in each microbial community was examined by using morphological analysis, small-...
متن کاملTracking microbial habitats in subseafloor sediments.
T hroughout the world’s oceans, the sediments that cover the seafloor, and the cracks and fissures of the basaltic ocean crust, are permeated by microbial life (1, 2). As these bacteria and archaea are mostly not available in laboratory culture and thus elude direct physiological characterization, Jørgensen et al. correlate geochemical regimes in subseafloor sediments with in situ abundance of ...
متن کاملLiquid Fuel Production from Synthesis Gas via Fermentation Process in a Continuous Tank Bioreactor (CSTBR) Using Clostridium ljungdahlii
The potential bioconversion of synthesis gas (syngas) to fuels and chemicals by microbial cell has attracted considerable attention in past decade. The feasibility of enhancing syngas bioconversion to ethanol and acetate using Clostridium ljungdahlii in a continuous tank bioreactor (CSTBR), kinetics and mass transfer coefficient of carbon monoxide (CO) utilization were evaluated. Two different ...
متن کاملBiodegradation of naphthalene using Pseudomonas aeruginosa by up flow anoxic–aerobic continuous flow combined bioreactor
BACKGROUND Naphthalene is a poly aromatic hydrocarbon (PAH) present in many sediment-water systems. The aim of this study was to evaluate the applicability of an anoxic/aerobic system for the biological treatment of water polluted by naphthalene by Pseudomonas aeruginosa PTCC 1707 to utilize naphthalene. The naphthalene elimination from wastewater was determined in anoxic-aerobic continuous flo...
