Answer 2

you can use a CO2 gas sensor on a known number of organisms.

Answer 3

Thanks @Yetter and aaronq. But do you know some other methods? Simpler than that in that paper? And what if I don't have a CO2 gas sensor?

Answer 4

@aaronq

Answer 5

I do not know of any simpler methods. I'm sorry.

Answer 6

Not without some method of detection of CO2, direct, or indirectly. You could (very crudely) determine the amount of CO2 present in air by measuring the pH of water.

Answer 7

Thanks loads people. Gonna check the possibilities out.

Answer 8

no problem. If you're interested in doing research where you don't already have equipment, i suggest at least getting a pH meter.

Answer 9

unless you don't mind doing lots of titrations

Answer 10

I prefer using the pH meter really :) Thanks again for the suggestions!

Answer 11

haha yeah, me too.
