I read "3 mo. old culture of bacteria" as "3 month old culture of bacteria."

Am I on the right track?

3 mo. old culture of bacteria isolated from crushed Pennsylvania coal. The lump from which these bacteria were isolated had first been baked for 10 hours at 160-170C and then incubated as an uncrushed lump in peptone medium for 39 days, which produced no growth. Credit: Lipman 1931

    I think that's the only thing it can mean.

    They've been growing in his lab for 3 months since he removed them from the coal.
