2.1. Test I – growth of G. sulphuraria in UWW
The goal of Test I was to demonstrate the ability of
G. sulphuraria
togrow ina mediumrepresentativeof typicalUWW(BOD:N:Pratio
of 16.5:13.4:1) and assess its BOD, N, and P removal capabilities. In
this test, the standard Cyanidium recipe for
G. sulphuraria
(
Selvaratnam et al., 2014a
) was modified as follows: instead of
using deionized water to prepare the standard growth medium, fil-
ter-sterilized (0.45
