Abstract
The transport system for glucose (as measured by deoxyglucose uptake) in the high temperature strain of Chlorella (strain 07-11-05 or C. sorokiniana) was constitutive and the rate of uptake did not increase upon incubation of autotrophically grown cells with either deoxyglucose or glucose. The uptake obeyed Michaelis-Menten type kinetics with a concentration of 200 Mmol for half-saturation. The maximum rate of uptake was nearly 10 times faster per cell (at 38.degree. C) than that reported for any other Chlorella. This rapid accumulation of deoxyglucose causes the passive efflux to become significant compared to the pump-driven influx and nonlinear uptake appears even after only 3-4 min.This publication has 10 references indexed in Scilit:
