Identification of Stabilization of Malvid Anthocyanins and Antioxidant Stress Activation via the AMPK/SIRT1 Signaling Pathway.

Rupr. "Beibinghong" is abundant in anthocyanins, including malvidin (Mv), malvidin-3-glucoside (Mv3G), and malvidin-3,5-diglucoside (Mv35 G). Anthocyanins offer nutritional and pharmacological effects, but their stability is poor.

Edaphobacter acidisoli sp. nov., an acidobacterium isolated from forest soil.

Two strains, 4G-K17 and 4G-K15, were isolated from forest soil from the Dinghushan Biosphere Reserve, Guangdong Province, PR China (112° 31' E 23° 10' N). The cells of the two strains were Gram-stain-negative, aerobic and non-motile short rods that multiplied by binary division. Strains 4G-K17 and 4G-K15 were obligately acidophilic, mesophilic bacteria capable of growth at pH 3.
