I am inoculating bacteria and fungi onto separate wood blocks. I know how to do the fungi, the bacteria I am struggling with as there appears to be different ways. I was going to grow bacteria in nutrient broth, measure OD of cells, the spin it down, decant the broth then repeat using Ringers twice to wash them. The resuspend in Ringers and but 2 mL into a bijou tube and put the wood block in the bijou tube for a period of time to allow bacteria to colonise. Does that sound like a viable option and if I leave it for a month will it affect the wood or the bacteria regarding oxygen in the Ringers?
