These metals are present in water as filterable and particulate metals. These metals were found to bioaccumulate in prawn samples along Veifa stretch of the Angabanga River. The analytical results showed that As as particulate metal was high in concentration at 86 μg·g^-1 and Pb as filterable metal was high in concentration at 12 μg·g^-1. The metals Pb and As also accumulated in prawns along the Veifa stretch but were within recommended toxic metal standards.展开更多

The samples from Amanitaceae family (KMsp027) and Mycenaceae family (KMsp039) were found to contain fatty acid methyl esters (methyl palmitate and methyl linoleate). It is proposed that the presence of methyl linoleate and methyl palmitate in the samples may show antibacterial activities if tested against different bacterial strains.展开更多
