Edaphobacter flagellatus sp. nov. and Edaphobacter bradus sp. nov., two acidobacteria isolated from forest soil.

Two aerobic and obligately acidophilic bacteria, designated HZ411 and 4MSH08, were isolated from the forest soil of Dinghushan Biosphere Reserve, Guangdong Province, PR China (23° 10' N, 112° 31' E). These two strains were Gram-stain-negative short rods that multiplied by binary division. HZ411 was motile, with a single polar flagellum, but 4MSH08 was non-motile.

Acidicapsa dinghuensis sp. nov., a novel acidobacterium isolated from forest soil.

A bacterial strain, designated 4GSKX, isolated from the forest soil of Dinghushan Biosphere Reserve, Guangdong Province, PR China (112° 31' E 23° 10' N), is proposed as a novel species of the genus Acidicapsa. Cells of strain 4GSKX were aerobic, non-motile, Gram-stain-negative short rods that multiplied by binary division. The strain grew at 12-37 °C (optimum, 25-30 °C), pH 4.
