telluria mixta telluria mixta telluria mixta (formerly called pseudomonas mixta) is a species of gram-negative soil bacteria that actively degrades polysaccharides including dextran, inulin, pectate, starch, and xylan. the bacterium is straight-rod-shaped, 0.5 to 1.0 μm wide and usually 2 to 3 μm long, and can grow both lateral and polar flagella. optimal growth is seen between 30 and 35 °c, at a neutral ph, and with no salt present. growth is totally inhibited in a sodium chloride concentration of 1.5% or more. a high level of nitrogenous carbon also inhibits growth. telluria mixta scientific classification domain: bacteria phylum: pseudomonadota class: betaproteobacteria order: burkholderiales family: oxalobacteraceae genus: telluria binomial name telluria mixta(bowman et al. 1989) bowman et al. 1993 synonyms pseudomonas mixta bowman et al. 1989 the name generic name telluria, meaning "from the earth", derives from tellus, the roman earth goddess.
