MARINE BACTERIA AND THEIR RÔLE IN THE CYCLE OF LIFE IN THE SEA I. DECOMPOSITION OF MARINE PLANT AND ANIMAL RESIDUES BY BACTERIA

摘要: The synthesis of organic matter in the sea through agency chlorophyll-bearing plants, ranging from smallest diatoms to largest algae, consists assimilation carbon as CO2, nitrogen nitrate, and probably a lesser extent ammonia nitrite, phosphorus phosphate, other elements lower concentrations. Before these can be returned circulation, after plants well animals which fed partly upon them die, complex substances have decomposed bacteria. If one is judge by analogy with decomposition processes take place on land, liberation mineralized form does not represent simple process, but rather chain processes. rate bacterial action depends primarily chemical composition materials undergoing organisms active following investigations were undertaken for purpose determining what marine residues plant animal origin influences their bacteria important elements, especially nitrogen, in. an available form. It was further essential obtain light mechanism some constituents specific members population sea. These classified, therefore, under three distinct headings, namely: (1) zo6plankton certain (2) plankton algal material water
