Removing air may only prevent those that live aerobically but there might also be those that are anaerobic (those that live in the absence of air), I'm not really sure but the factor that seems to be common for them to live is the humidity or presence of water or moisture.
It would be more of remove the H20 and that would prevent the fungus to grow that is why most dry cabinets have a hygrometer to monitor the moisture in the air.
There are portable hygrometers sold at Walmart or even at Ebay.
There should be plenty of materials on the internet for what relative humidity to maintain to prevent fungus growth and that is what you just need to achieve with the hygrometer.
It is also best that dry cabinets (with clear windows or transparent) are exposed to daylight since UV (correct me if I'm wrong) is detrimental to the fungus' growth..so actually exposing contaminated lens to the sun for long periods of time kills them.
