Separation of spores and parasporal crystals of Bacillus thuringiensis in gradients of certain x-ray contrasting agents.
Spores and parasporal crystals of Bacillus thuringiensis can be separated at moderate centrifugation speeds (10,000 to 12,000 rpm) in gradients of Renografin or sodium diatrizoate.
