How aout a french press?
>I am working with a Gram + bacterium (Arthrobacter nicotinovorans). Part

>proteins present on cell extracts of this bug. I use to prepare my cell 
>extracts with a sonifier, but this procedure is very unefficient. 
>I added enzymes (lysozyme and/or mutanolysin, both from Sigma) prior
