METPO provides terms for microbial ecophysiological traits and phenotypes: growth preferences (temperature, pH, salinity, oxygen), metabolism, and cell morphology of bacteria and archaea. Its primary purpose is to harmonize terminology across major microbial trait databases (BacDive, BactoTraits, Madin bacteria_archaea_traits, MetaTraits) for use in KG-Microbe. METPO uses OBO-style annotation patterns (IAO textual definitions, oboInOwl synonyms) and cites terms from OMP, MicrO, GO, ECOCORE, and PATO as definition sources.

Positive form of the chemical-tolerance pair; the negative form is METPO:2000065 'does not tolerate'. tolerates A relation between a microbe and a chemical entity indicating that the microbe's growth is inhibited by the chemical at the concentration tested. Negative form of the chemical-tolerance pair; positive form is METPO:2000064 'tolerates'. Equivalent in meaning to 'is susceptible to' and 'is sensitive to'; the canonical label uses the 'does not X' convention so the metatraits pairing logic auto-detects it as the negative member. does not tolerate A relation between a microbe and a quality of the host from which the microbe was isolated. Examples: a microbe isolated from a juvenile host has the relation `<microbe> METPO:2000067 PATO:0001190 'juvenile'`; a microbe isolated from a female host has the relation `<microbe> METPO:2000067 PATO:0000383 'female'`. The relation is one-directional: it asserts that the host bore the named quality at isolation time, not that the microbe itself has the quality. isolated from host with quality A relation between a microbe and a quality of the environment from which the microbe was isolated. Examples: a microbe isolated from an acidic environment has the relation `<microbe> METPO:2000068 PATO:0001429 'acidic'`; a microbe isolated from an anaerobic environment has `<microbe> METPO:2000068 PATO:0001456 'anaerobic'`. The relation does not by itself entail that the microbe is acidophilic, anaerobic, etc. as a phenotype; it only records the environment's quality at the time of isolation. Microbe phenotype assertions belong on a separate edge (e.g. METPO:1000615 acidophilic via has_phenotype). isolated from environment with quality has quality has phenotype capable of dismutates disproportionates dismutates obsolete lyses true produces produces produces obsolete fixes true obsolete catabolizes true obsolete mineralizes true obsolete conjugates true transports imports exports accumulates sequesters compartmentalizes obsolete binds true obsolete chelates true obsolete precipitates true obsolete solubilizes true obsolete volatilizes true obsolete crystallizes true obsolete adsorbs true dismutates does not disproportionate dismutates obsolete does not lyse true produces does not produce produces obsolete does not fix true obsolete does not catabolize true obsolete does not mineralize true obsolete does not conjugate true does not transport does not import does not export does not accumulate does not sequester does not compartmentalize obsolete does not bind true obsolete does not chelate true obsolete does not precipitate true obsolete does not solubilize true obsolete does not volatilize true obsolete does not crystallize true obsolete has pH observation true Physiology and metabolism.enzymes.[].activity enzyme activity analyzed Physiology and metabolism.enzymes.[].activity Physiology and metabolism.enzymes.[].activity shows activity of Physiology and metabolism.enzymes.[].activity Physiology and metabolism.enzymes.[].activity does not show activity of Physiology and metabolism.enzymes.[].activity obsolete has optimum pH observation true obsolete has growth pH observation true obsolete has range pH observation true obsolete has pH delta observation true obsolete has culture pH observation true obsolete has NaCl observation true obsolete has optimum NaCl observation true obsolete has growth NaCl observation true obsolete has range NaCl observation true obsolete has NaCl delta observation true obsolete has observation true obsolete has oxygen observation true obsolete has optimum oxygen observation true obsolete has growth oxygen observation true obsolete has range oxygen observation true obsolete has oxygen delta observation true A relation between a microbe and a growth medium indicating that the microbe has been demonstrated to grow in that medium under some set of conditions.
