Electron transport system activity of microfouling material: Relationships with biomass parameters
Abstract
Microfouling material developed on aluminium panels immersed in surface waters of the Dona Paula Bay, Goa India was analysed for biomass (measured as dry weight, organic crabon, protein and chlorophyll @ia@@) and electron transport system actitity (ETS). The ETS activity ranged from 720 to 1374 ~kg 0@d2@@ dm@u2@@ d@u-1@@. Microfouling biomass and ETS activity of microfouling material increased with the immersion period. ETS activity was significantly correlated with dry weight, organic carbon, protein and chl @ia@@. At low chl @ia@@ levels microheterotrophs play a major role in the overall respiration, however at high chl @ia@@ concentrations, microalgae can dominate respiration in a microfouling community
