Respiration von gelösten organischen Verbindungen durch natürliche Mikroorganismen-Populationen. Ein Vergleich zwischen verschiedenen Biotopen

In 5 different biotopes (sea water, brackish water, lake, river, and sewage waters), respiration, as percent of the total uptake of 9 compounds and an amino-acid mixture, was studied. Strong variations between the biotopes could be demonstrated. Percentage respiration values varied between 11 and 57% for glucose, 20 and 37% for glucosamine, 13 and 36% for glycerol, 28 and 68% for aspartic acid, 1 and 16% for leucine, 3 and 19% for lysine, 15 and 64% for acetate, 15 and 60% for lactate, 52 and 79% for malate and between 21 and 36% for the amino-acid mixture. Despite these variations, the two amino acids leucine and lysine showed the lowest percentage and the two C 4-compounds aspartic acid and malate the highest percentage respiration in each biotope.
