Surface water (top 50 cm) was collected with a 2 L water sampler. Subsamples of 300–500 ml water for 16S rRNA gene analysis were filtered on 0.2 μm pore-size polycarbonate filter (Millipore) using a hand-driven vacuum pump in the field. The filters were stored at − ...
1. The aerator suspended in deep water inhales the oxygen-poor water in the lower layer, and then shoots rapidly into the air from the nozzle to form a fountain, dispersing into water droplets of different sizes into the fish pond. During this period, countl...
Lake Como, the deepest lake in Italy, provides substantial ecosystem services, including drinking water, recreational uses, industrial uses, and irrigation. However, its location in a heavily industrialized area means it is subject to pollution from watershed activities and even from melting glaciers ...
