Hydrodynamic conditions affect the proteomic profile of marine biofilms formed ...

Proteomic studies on cyanobacterial biofilms can be an effective approach to unravel metabolic pathways involved in biofilm formation and, consequently, obtain more efficient biofouling control strategies. Biofilm development by the filamentous cyanobacterium Toxifilum sp. LEGE 06021 was evaluated on different surfaces, glass and perspex, and at two significant shear rates for marine environments (4 s(-1) and 4...

Characterization of planktonic and biofilm cells from two filamentous cyanobact...

Cyanobacteria promote marine biofouling with significant impacts. A qualitative proteomic analysis, by LC-MS/MS, of planktonic and biofilm cells from two cyanobacteria was performed. Biofilms were formed on glass and perspex at two relevant hydrodynamic conditions for marine environments (average shear rates of 4 s(-1)and 40 s(-1)). For both strains and surfaces, biofilm development was higher at 4 s(-1). Biofi...

A conceitualização do princípio de conservação da energia mecânica: os processo...

Este trabalho investiga o processo de apreensão do princípio de conservação da energia mecânica por alunos em diferentes momentos da instrução formal. O trabalho é justificado pelos relatos existentes acerca da complexidade que envolve o conceito de energia, o princípio de conservação da energia, degradação e conversão relacionadas aos materiais didáticos, à sua estrutura epistemológica racional e, principalmen...
