    摘要： This invention relates to the production of citric and/or isocitric acids. The production of citric and/or isocitric acids is effected by cultivating a citric and/or isocitric acid-producing yeast in a culture medium containing a compound selected from cyanoacetic acid, and organic and inorganic derivatives thereof. Increased yields of citric and isocitric acids are obtained using a process in accordance with the invention, preferably using a yeast of the genus Candida.

    摘要： Device for generating acoustic waves in a fluid medium by implosion, comprising a main cylinder, a main piston slidably mounted thereinto, said piston having a hollow cylindrical portion housing another cylinder solid with the main one and, through the bottom of which passes the hollow rod of another piston, actuated by hydraulic means and which drives in translation the main piston. By means of an annular valve, solid with the main piston, and further hydraulic means, the main piston may be locked in a position of spaced relationship with respect to the main cylinder and abruptly unlocked, thereby generating an implosion.
