Observations on the Microbial Biomass in two Stations of Terra Nova Bay (Antarctica) by ATP and LPS Measurements
Abstract. This paper reports on the temporal distribution of microbial biomass, over a I‐month survey during austral suinmer 1990. at two sampling stations in Terra Nova Bay (Antarctica) by means of biochemical methodologies such as ATP (adenosine triphosphate) and LPS (lipopolysaccharides).
