Mechanical treatments particularly bead milling are widely used to disrupt cells 1617it is therefore important to demonstrate the capacity of microorganisms to carry out anaerobic fermentation of soluble substrates in the presence of continuous ball milling at an intensity sufficient to enable high total carbohydrate solubilization
Particle size and standard deviation cpm for most feed materials ground through a roller mill the lognormal standard deviation will be in the range of 2 to 25 for most feed materials ground through a hammermill the lognormal standard deviation will be from 25 to 35 view more details
The effect of the ball milling time bmt on the substitution of the carbon in the glucose doped mgb 2 samples is investigated here using in situ solid state reaction four different doped samples of mgb 98 c 02 2 were prepared by mixing powders of mg boron and glucose for 2 h 4 h 8 h and 12 h using planetary ball milling
