Autor: Luisa Siliato, Neil Tomas William Ellwood, Francesca Di Pippo, Patrizia Albertano, Antonella Guzzon, Ernesto Micheletti, Roberto De Philippis

Publikováno v: Journal of Applied Phycology. 24:211-220

Phototrophic biofilms seem to be suitable candidates for tertiary wastewater treatment due to their high uptake capacity for nutrients and other pollutants, also taking into account the time and cost savings derived from easy procedures for biomass h

Autor: Ernesto Micheletti, Patrizia Albertano, Siba Prasad Adhikary, Laura Bruno, Roberto De Philippis, Federico Rossi

Three coccoid and two filamentous cyanobacterial strains were isolated from phototrophic biofilms exposed to intense solar radiation on lithic surfaces of the Parasurameswar Temple and Khandagiri caves, located in Orissa State, India. Based on to the

Exopolysaccharide-producing cyanobacteria in heavy metal removal from water: molecular basis and practical applicability of the biosorption process

Autor: Ernesto Micheletti, Giovanni Colica, Roberto De Philippis

Publikováno v: Applied microbiology and biotechnology. 92(4)

Microorganisms can remove metals from the surrounding environment with various mechanisms, either as metabolically mediated processes or as a passive adsorption of metals on the charged macromolecules of the cell envelope. Owing to the presence of a

Using extracellular polymeric substances (EPS)-producing cyanobacteria for the bioremediation of heavy metals: do cations compete for the EPS functional groups and also accumulate inside the cell?

Autor: Paula Tamagnini, Sara Pereira, Ernesto Micheletti, Andrea Zille, Pedro Moradas-Ferreira, Roberto De Philippis, Arlete Ramos dos Santos

Publikováno v: Microbiology (Reading, England). 157(Pt 2)

Many cyanobacteria produce extracellular polymeric substances (EPS) mainly of polysaccharidic nature. These EPS can remain associated to the cell surface as sheaths, capsules and/or slimes, or be liberated into the surrounding environment as released

Heavy Metal Removal with Exopolysaccharide-Producing Cyanobacteria

Autor: Ernesto Micheletti, Roberto De Philippis

Publikováno v: Handbook of Advanced Industrial and Hazardous Wastes Management ISBN: 9781315117423

Heavy metals are one of the most widespread causes of pollution, both in water and in the soil, and the presence of increasing levels of these metals in the environment is causing serious concern in public opinion owing to the toxicity shown by most

Publikováno v: Applied and Environmental Microbiology. 74:5266-5266

Cyanobacteria are a large and widespread group of photoautotrophic microorganisms that combine the ability to perform an oxygenic plant-like photosynthesis with typical prokaryotic features (40). Outside their atypical gram-negative cell walls (15),
