densities, and both 2.5 mM and 5.0 mM glucose addition to
the culture medium had the same effect on the growth of
Chlorella sp. In contrast, growth was seriously inhibited by
the presence of sodium thiosulphate alone and the degree
of inhibition increased sharply with an increase of sodium
thiosulphate concentration. However, the inhibition of
sodium thiosulphate was almost completely eliminated by
adding glucose in medium.
