Once Brett gets going it really doesn't need much oxygen. Actually, the pellicles that various strains form are their way of protecting the wort from the introduction of even more oxygen (& other things too I'm sure.)

Only thing I can think of is a 2006 or 2007 Brewing Network interview with the editor of BYO. Not sure they went into too much detail on the biology of Brett in particular, but I could be wrong on that...

After 9 or so Brett sours, I've never got a thick lumpy pellicle. I only get the thin spider-web slimy ones. I use glass with an airlock. The pellicle is more likely to form if the airlock dries out or if I open it and sample it. I also primarily use lactobacillus with decent amount of sourness early on. I wonder if the lumpy pellicle is more likely to form when pediococcus is the predominant souring agent.
