Aerobic and anoxic growth and nitrate removal capacity of a marine denitrifying...
Borges, Maria-Teresa; Sousa, André; Marco, Paolo De; Matos, Ana; Hönigova, Petra; Castro, Paula M. L.Bacterial biofilters used in marine recirculation aquaculture systems need improvements to enhance nitrogen removal efficiency. Relatively little is known about biofilter autochthonous population structure and function. The present study was aimed at isolating and characterizing an Autochthonous denitrifying bacterium from a marine biofilter installed at a recirculation aquaculture system. Colonization of four ...
Labrys portucalensis sp. nov., a fluorobenzenedegrading bacterium isolated from...
Carvalho, Maria F.; Marco, Paolo De; Duque, Anouk F.; Pacheco, Catarina C.; Janssen, Dick B.; Castro, Paula M. L.A detailed classification of a novel bacterial strain, designated F11T, capable of degrading fluorobenzene as a sole carbon and energy source, was performed by using a polyphasic approach. This Gram-negative, rod-shaped, non-motile, non-spore-forming, aerobic bacterium was isolated from a sediment sample collected from an industrially contaminated site in northern Portugal. The predominant whole-cell fatty acid...
Enrichment of microbial cultures able to degrade 1,3-dichloro-2 propanol: A com...
Bastos, Filipe; Bessa, José; Pacheco, Catarina C.; Marco, Paolo De; Castro, Paula M.L.Microbial cultures able to degrade xenobiotic compounds are the key element for biological treatment of waste effluents and are obtained from enrichment processes. In this study, two common enrichment methods, suspension batch and immobilized continuous, were compared. The main selection factor was the presence of 1,3-dichloro- 2-propanol (1,3-DCP) as the single carbon source. Both methods have successfully enr...
