Hydrolase production reflects what a microbe can enzymatically do to break down substrates, which is a key part of its metabolic profile. In diagnostic microbiology, labs test for these hydrolytic activities to build a biochemical fingerprint of an organism. Because many hydrolases are common across microbes but are expressed differently across species, the pattern of which substrates are hydrolyzed helps differentiate pathogens and support identification. So using the presence or absence of hydrolase activities to infer metabolic capabilities and identify organisms is a valid and practical approach.

Bacteria, not just eukaryotes, produce hydrolases, so the idea that only eukaryotes do this is incorrect. These tests don’t measure antibiotic resistance, and while hydrolase production is widespread, assessing which hydrolytic activities a microbe has is indeed useful for identification.
