Is Using One Way ANOVA appropriate?

Our school project requires Statistical Analysis and I'm not quite knowledgable about it. I'm reading right now and I've learned some things but I'm still confused.

So what I did was I used different sponges with different doses to test their antimicrobial effect. So basically, pathogens were placed in wells and different extracts with different doses from different sponges were used.

I had sponges 1-7 with a high dose, medium dose and low dose.
I have 4 controls sterility control (no pathogen and extract),
growth control(with pathogen only), positive control (with antibiotic and pathogen) and negative control.

I assume there should be only one control which is growth control and sterility ,negative and positive should be considered as treatments.

So to summarize I had 7 sponges with different doses. I also had different treatments.

My question is should I use one-way anova here. If not, what should be the most appropriate?
Another is, should I remove sterility control here since it was simply a test for sterility?
