I think they're E.coli but im not sure. I gram stained them both and they're both gram-negative (i think). The first one was from a source with a bunch of contimates. The sceond sample was from one of the individual cultures from the original contiminated sample. I assumed the first sample had E.Coli, but from the second sample it doesn't look entirely like the first. Could it be because i inoculated the wrong colony or because i only let the second sample grow for a day? I'm really new to this so any information would be helpful, thank you!
