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). Chloride: less than 250 mg/litre (from seawater contamination). 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. Total viable count (TVC) standard is ‘no abnormal change’. 25 Related Questions and Answers How can I get TVC from TFC and output? To determine the total variable cost the company will spend to produce 100 units of product, the following formula is used: Total output quantity x variable cost of each output unit = total variable cost. … Thus, the TC curve is the same shape as TVC but begins from the point of TFC rather than the origin. Since the TFC curve is horizontal, the difference between the TC and TVC curve is the same at each level of output and equals TFC. TVC may also be expressed as aerobic colony count. What is a TVC sample? Total viable count (TVC) is a test that estimates the total numbers of microorganisms, such as bacteria, yeast or mould species, that are present in a water sample.

Total variable cost (TVC) reflects diminishing marginal productivity - as more variable input is used, output and variable cost will increase.

Total fixed cost (TFC) is constant regardless of how many units of output are being produced.
