Is tetragenococcus halopphilus gram positive or gram negative?

Answer: they are gram negative

Explanation:

The cells are nonmotile, spherical, and occasionally ovoid and divide in two planes at right angles to form tetrads. Cells may also form pairs or occur singly, especially during early or midexponential growth. Individual cells measure 0.5-1.0 µm. The cells are Gram-positive, asporogenic, and catalase - and oxidase-negative.
