Discovery NotesSample Information
Date collected: 9/1/2025
Location: Verona, Kentucky, United States
Weather on the day the sample was collected:
temperature 27.222°C, sunny, and minimal humidity.

Physical Characteristics of Dirt Sample:
-Very Dry
-Crumbly texture(due to dryness)
-Sample was collected an 1-2cm below surface.
Naming NotesOpalite is a man-made gemstone that is translucent. This name was selected because the gemstone opalite signifies optimism for the future. In addition, its translucent characteristic aligns with this phage's turbid phenotype.

Plaque NotesPlaque phenotypes:
-Extremely turbid
-Contained plaques of varying sizes

Standard deviation and mean of plaque diameters were calculated on 10/14.

Large Plaques (sample of 5)
standard deviation: 0.1095cm
mean: 0.42cm

Small Plaques (sample of 5)
standard deviation: 0.0837cm
mean: 0.22cm

On 10/14 there was a change in plaque morphology. Plaques observed were less turbid that previous plaques. This new phenotype remained consistent for the remainder of experiments.
