The API 20E system is a biochemical test used for the identification of Enterobacteriaceae and other non-fastidious gram-negative bacteria. The results for a specific test, such as the one with the reference number 1214373, would typically include a profile of the organism's metabolic capabilities based on various carbohydrate and enzyme reactions. To obtain specific results for that reference number, you would need to consult the laboratory report associated with that test, as it contains detailed interpretations of the biochemical reactions observed.
In microbiology, the abbreviation API stands for Analytical Profile Index, which is a method used to identify and classify bacteria based on their biochemical characteristics. This system uses a series of biochemical tests to compare the growth patterns of an unknown bacteria with a database of known bacteria for identification.
Performing the reagent tests last in the API 20E system helps to prevent cross-reactions between the other test results and thus ensure accurate identification of the microorganism based on its biochemical profile. It also helps to minimize the risk of false-positive or false-negative results that could occur if the reagents interact with the components of the other tests.
Using an API 20 E sheet.. then you use the book containing different API 7 digit numbers to identify your bacteria

The value of 1 kg of heavy crude will be between 1.0 to 1.0714 liters. Definitions of heavy oil vary. Generally, a range of 10 degrees to 20 degrees API is one qualifier, and the viscosity of the oil is a second qualifier. Specific gravity (SG) = 141.5/(131.5 + API) where API = degrees API density. So, 20 degrees equals SG of 0.9333. This is equal to 0.9333 kg/ liter, so 1 liter = 1/0.933 = 1.0714 kg. For 10 degrees API, SG = 1. See related links for discussion of heavy oil and tars.
