Fig. 1: Morphology, characteristics and genome organization of phage vB_VspM_VS2.

A Transmission electron micrograph showing that vB_VspM_VS2 belongs to the family Myoviridae and has a head of 122 × 140 ± 5 nm and a tail of 30 × 50 ± 5 nm. B Plaques formed by vB_VspM_VS2 on the host strain V. splendidus after overnight incubation at 28 °C. C, D Adsorption rate and population dynamics of vB_VspM_VS2 inoculated in V. splendidus culture. The values presented are means and standard deviations (SDs) of three independent biological repeats (n = 3). E Line map of the vB_VspM_VS2 genome. In the vB_VspM_VS2 genome track, the arrows represent the ORFs and point in the direction of transcription. The color intensity corresponds to G + C skew level. F Growth curve of V. splendidus. At the time of 4.5 h, the bacteria began to grow rapidly that enter the growth phase of exponential until 16 h. a: early exponential stage (EES, 4.5 h), b: middle exponential stage (MES, 10 h), c: late exponential stage (LES, 16 h), d: stationary growth stage (SGS, 31 h).
