原始语种摘要: Abstract(#br)The shielding role of ferric iron (FeCl3) and certain cyanobacterial pigments (a brown‐colored pigment from Scytonema hofmanii culture filtrate and a pink extract from Nostoc spongiaeforme ) against UVB‐induced damage in the filamentous, nitrogen‐fixing cyanobacterium Nostoc muscorum has been demonstrated. Addition of these colored compounds to agarose gels (1–3 mm thick) resulted in a considerable decrease in UVB transmittance through the gels. The lowest UVB transmittance (15%) occurred through a 3 mm gel containing 0.01% FeCl3 followed by S. hofmanii culture filtrate (40%) and N. spongiaeforme extract (50%). These substances appear to act as very efficient UVB‐absorbing screens. Percent survival and 14CO2 uptake of N. muscorum...
