Table 1. Classification and general features of C. salexigens according to the MIGS recommendations [21].

MIGS ID	Property	Term	Evidence code
	Current classification	Domain Bacteria	TAS [22]
		Phylum Proteobacteria	TAS [23]
		Class Gammaproteobacteria	TAS [24,25]
		Order Oceanospirillales	TAS [24,26]
		Family Halomonadaceae	TAS [27-31]
		Genus Chromohalobacter	TAS [2,32]
		Species Chromohalobacter salexigens	TAS [1]
		Type strain 1H11	TAS [1,4]
	Gram stain	negative	TAS [1]
	Cell shape	rod-shaped	TAS [1]
	Motility	motile	TAS [1]
	Sporulation	none	TAS [1]
	Temperature range	mesophilic, 15–45°C	TAS [1]
	Optimum temperature	37°C	TAS [1]
	Salinity	halophilic and halotolerant. Salinity range from 0.9 to 32% (w/v) NaCl in rich media,      2.9% to 19% (0.5 M to 3.75M) NaCl in minimal media;     halotolerance increased by osmoprotectants;     halotolerance decreases at high temperature.	TAS [1,4,6,33]
MIGS-22	Oxygen requirement	uses O2 and NO3- as electron acceptors; does not grow fermentatively	TAS [4]
	Carbon source	various organic acids, alcohols, sugars, and aromatic compounds	TAS [1]
	Energy metabolism	chemoorganotrophic	NAS
MIGS-6	Habitat	saltern, fresh water	TAS [4]
MIGS-15	Biotic relationship	free living	TAS [1]
MIGS-14	Pathogenicity	none	NAS
	Biosafety level	1	TAS [34]
	Isolation	solar salt facility, concentration more than 10% NaCl	TAS [1]
MIGS-4	Geographic location	Bonaire, Netherlands Antilles	TAS [1]
MIGS-5	Sample collection time	June 1974	TAS [4]
MIGS-4.1	Latitude	12.25	NAS
MIGS-4.2	Longitude	-68.26	NAS
MIGS-4.3	Depth	surface	NAS
MIGS-4.4	Altitude	sea level	NAS

Evidence codes - TAS: Traceable Author Statement (i.e. a direct report exists in the literature); NAS: Non-traceable Author Statement (i.e. not directly observed for the living, isolated sample, but based on a generally accepted property for the species, or anecdotal evidence). These evidence codes are from of the Gene Ontology project [35].
