Method for the destruction of microbial cells


, : Method for the destruction of microbial cells. Prikl Biokhim Mikrobiol 3(3): 347-351

A desintegrator was developed to grind microbial cells. The ground material cooled at [long dash]40[long dash]45[degree] C was squeezed (at a pressure of 250-300 atm) through a slit with a clearance of 0.3-0.5 mm. The cells were destroyed with ice crystals. The performance of the apparatus was evaluated by the amount of cells remaining intact as well as by the inhibition of active proteins and subcellular structures in the supernatant after centrifugation. The apparatus was tested in several laboratories. The results were positive.
