RESPIRATION OF BACTERIA
We at Columbus Instruments developed very sensitive O2/CO2 RESPIROMETER
(Micro-Oxymax) which measures bacteria respiration with 0.2 microliter
With optional CO2, CH4, H2 , H2S and NH3 sensors can be used for anearobic
situations. It monitors 1 to 80 samples which can be liquid or solid. It
is based on
monitoring head space gas by one set of external sensors having 0.001%
resolution. It is currently being used for testing biodegradation of oil,
plastic polymers, TNT, creozote, respiration of algea, soil respiration,
coffee oxidation, toxicity etc.
It operates on closed chamber principle with periodic air (or ather gas)
It can also operate in open flow principle for monitoring high bioactivity
or sludge, fermentation etc.
Samples can be of any size from grams to many kg.
We have number of application papers ( and catalog) which we can send on
