A
ferricyanide-mediated rapid BOD approach has been reported to overcome the
oxygen solubility in water limitation that contributes to long incubation time
(5 days) in the standard BOD test (BOD5), internationally employed
as a water quality parameter. BOD test is used to determine organic pollution
in natural waters and the total degradable organic load in wastewaters.
Here
we present results obtained using free bacterial cells, in a batch system. Our results
show that one of the bacterial strains tested reduces ferricyanide efficiently
and is able to oxidize several carbon sources. These results are going to be
used in the design of a microbial biosensor that, proficient for BOD rapid
determination, will improve and facilitate active intervention in environmental
monitoring. The development of rapid methods to be used in-situ, based in
disposable electrochemical strips, is our ultimate goal.
