was continuously sparged through the diffuser to maintain the desired oxygen concentration in the
aerator. Fig. 1 shows the whole experimental set-up. It was started with 1% (w/v) synthetic glucose
media in batch mode.The medium was inoculated with acclimatized aerobic culture. After the reactor
was stabilized continuous feeding was started. Untreated textile wastewater fed as influent to the
reactor was brought from a textile industry near Delhi, India. The untreated wastewater mixed with
1% (w/v) glucose media was fed to the aeration tank through a peristaltic pump of variable capacity,
which was calibrated before the start-up of the experiment as well as occasionally during the start up
of the reactor. The composition of synthetic glucose media is given in Table 2. Details of the
experimental set-up are given in Tables 3 and 4.sparged
