Background information
Carbon assimilation test is based on the ability of a bacterial species to utilize an organic compound (e.g. D-glucose) as a sole carbon source. This means that for carbon assimilation tests, any compound that is a potential source of carbon is considered a contaminant (e.g. Maltose for glucose assimilation test).
Question
What D-glucose grade can be used in glucose assimilation test in bacteriology, specifically, Acinetobacter species bacteria?
For example, this product (DEXTROSE MONOHYDRATE Extra Pure) https://www.alphachemika.co/chemical/2120/DEXTROSE_MONOHYDRATE_Extra_Pure.html says that it has 0.01% maltose, is this significant?
