Staphylococcus arlettae
Species of bacterium
From Wikipedia, the free encyclopedia
Staphylococcus arlettae is a gram-positive, coagulase-negative member of the bacterial genus Staphylococcus consisting of clustered cocci. It has been isolated from the skin of mammals and birds and is novobiocin resistant.[1] A strain of this species isolated from effluent from a textile factory was found to be able to degrade azo dyes.[2]

Some strains of S. arlettae are highly salt tolerant and commonly found in marine environment.[3] S.I. Paul et al. (2021)[3] isolated and identified salt tolerant strains of S. arlettae (strains ISP142A, ISP172C and ISP192A) from Cliona viridis sponges of the Saint Martin's Island Area of the Bay of Bengal, Bangladesh.
