Abstract: Anaerobic processes were studied in Tubifex and other aquatic invertebrates. After the aerobic-anoxic transition of Tubifex, succinate accumulated up to about 25 ฮผmol/g Wd within the first hour of anoxia, but steady-state levels were established after 4hr at only 10 ฮผmol/g Wd in an open-flow system.
Proprionate accumulated after a lag of 30 min and reached steady-state concentrations of about 30 ฮผmol/g Wd after 5 h of anoxia.
Lactate concentrations did not increase above 4 ฮผmol/g Wd under anoxia. Its accumulation was not induced by exposure to a blood extract, although Tubifex has the potential for lactate production.
The initial rates of glycolytic endproduct accumulation were increased in the presence of the deproteinized blood extract by 60% (succinate, 0โ30 min anoxia) and by 50% and 90% (proprionate, 30โ60 min anoxia; 1% and 2% blood extract, respectively). The maximum and steady state levels of these metabolites were not influenced by the hydrolysate of blood.
Aerobic and anaerobic heat dissipation of Lumbriculus variegatus was stimulated by the addition to the medium of a deproteinized hydrolysate of bovine blood. Oxygen uptake of Cyclops abyssorum increased similarly upon the addition of the blood extract under hypoxia. โข Keywords: Twin-Flow
