You can have bugs plus a meals supply, but there need to be oxygen for your bugs to make the most of during the biodegradation process. This is amongst the explanation why we tension the value of beginning having a sample that's saturated with oxygen.
Lots of micro organisms practical for BOD assessment are comparatively simple to keep up in pure cultures, mature and harvest at low cost. What's more, the usage of microbes in the sphere of biosensors has opened up new opportunities and rewards which include relieve of managing, planning and low priced of system. Many pure cultures, e.g. Trichosporon cutaneum, Bacillus cereus, Klebsiella oxytoca, Pseudomonas sp.
