    Notes: Abstract The static and dynamic magnetic dipole moments of odd-mass and even-mass nuclei with 150〈A〈190 have been compiled and analyzed in a systematic way, in order to extract the best set of collective rotational g-factors gR and intrinsic g-factors gK.

    Ein neues Verfahren zur zweistufigen Kultivierung von Mikroorganismen. Teil I. Prinzip des Verfahrens (1988)

    Notes: The importance of the two-step process technology in the field of biotechnological processes is demonstrated. Its application especially is pointed out to waste water treatment. The general advantages of such processes exist in its possibility to use different strains of microorganisms in an effective way and to realize parameters of the technological process in a defined sequence. But with the application of two-step process techniques (add of biomass to the second step) an extension of retention time is connected with a decrease of yield coefficient. This disadvantage may be eliminated by an inactivation of microorganisms after the first step. The inactivation of microorganisms can be realized by increase of temperature, of pH-value or by addition of toxic substances. The inactivated microorganisms act as inert particles in the second step not utilizing substrate and oxygen. The new process regime has a lot of advantages, eg. increase of biomass concentration, increase of utilization of complexe substrates and possibility of coupling different biotechnological processes.

    A new procedure of a two-step cultivation of microorganisms. Part II. Application to the procedure of SCP-production on the basis of sucrose (1990)
    Berlin : Wiley-Blackwell
    Acta Biotechnologica 10 (1990), S. 311-316

    Notes: The two-step cultivation of microoganisms described in part I of this series will be explained by referring to its application to the production of SCP on the basis of sucrose/molasses as carbon sources. The inactivation of the yeast Candida utilis is carried out thermally, and the specific death rate was determined to be between 119 × 10-4 s-1, and 324 × 10-4 s-1, respectively. With this new procedure the apparent productivity could be increased by 96.6%, the yield coefficient of molasses increased by 5.8% and of sucrose by 12.9%. The crude protein content of the product in the case of sucrose rose by 104%. The variability of process design is demonstrated.
