Lactococcus formosensis sp. nov., a lactic acid bacterium isolated from yan-tsai-shin (fermented broccoli stems).

A coccal-shaped organism, designated 516(T), was isolated from yan-tsai-shin (fermented broccoli stems), a traditional fermented food in Taiwan. 16S rRNA gene sequencing results showed that strain 516(T) had 98.9 % sequence similarity to that of the type strain Lactococcus garvieae NBRC 100934(T).

Enterococcus saccharolyticus subsp. taiwanensis subsp. nov., isolated from broccoli.

A coccal strain isolated from fresh broccoli was initially identified as Enterococcus saccharolyticus; however, molecular identification and phenotypic traits did not support this identification. DNA-DNA hybridization with the type strain of E. saccharolyticus (76.

Enterocin T, a novel class IIa bacteriocin produced by Enterococcus sp. 812.

Enterococcus sp. 812, isolated from fresh broccoli, was previously found to produce a bacteriocin active against a number of Gram-positive bacteria, including Listeria monocytogenes. Bacteriocin activity decreased slightly after autoclaving (121 °C for 15 min), but was inactivated by protease K.
