Chew


The substances appeared to make it easier for gut bacteria to chew through the layers of mucus that typically line the intestine.
Could you tell me what "chew" means in the sentence? It seems to be an intransitive verb, but I can't find the suitable definition of the verb in my dictionary. Thanks in advance!

The sentence is quoted from http://www.scientificamerican.com/podcast/episode/music-s-physiological-effects-transcend-culture/
