Besides, What is ooh stand for?

Also, What is a TVC test?
TVC stands for ‘total viable count’, a laboratory test that indicates the level of heterotrophic organisms within a sample. … TVC samples may be incubated at different temperatures depending on the environment sampled for example; it’s normal to incubate samples from potable water systems at 22˚C or 37˚C.
Herein, Is TVC same as ACC? Here at Express Micro Science we use TVC (total viable count) but other common terms are APC (aerobic plate count) and ACC (aerobic colony count). … ACC is short for aerobic colony count, so incorporates both criteria that the bacteria being reported grow in the presence of oxygen and are capable of forming colonies.
What are safe levels of Legionella in water?
Potable water standards
Legionella less than 100 cfu/litre. Total viable count (TVC) standard is ‘no abnormal change’. A TVC @ 37º of 10 cfu/ml and a TVC @ 22º of 100 cfu/ml are recommended as upper limits at which investigation/disinfection should be carried out.
