lipase activity

traitmech:000139 · CLASS · PROPOSED

A physiological enzyme-activity phenotype in which a cell produces active lipases that hydrolyze triglycerides at lipid-water interfaces.

Trait evidence (2)

DOI:10.22207/JPAM.16.4.27
Lipase-producing bacteria were isolated using tributyrin agar as a selective medium

Savalia and Dungrechiya used tributyrin agar to isolate lipase-producing bacteria from waste samples.
DOI:10.1016/j.mex.2018.01.004
to identify lipase producers. The addition of calcium and magnesium ions can provide an easier screening procedure for selection of lipolytic bacterial strains

Carrazco-Palafox et al. optimized modified tributyrin agar as a microbial lipolytic-activity screen.

CURATION TODO OPEN lipase-activity-xref-gap · raised by codex · 2026-09-11

Not yet attached to a section of this record — a curator sets attaches_to (e.g. causal_graphs#some_edge) so the gap shows beside the mechanism it concerns.

GO:0016298 denotes the lipase molecular function rather than the organism-level lipase production phenotype, so it is too scope-shifted for an equivalent TraitRecord xref.
