Abstract: In a process for preparing Moenomycin by the aerobic fermentation of Moenomycin-forming Streptomyces in the presence of fats, the improvement wherein a surfactant of the formula RO-(CH2CH2O-)nH is present in the fermentation medium, R being saturated or monounsaturated hydrocarbon having 8 to 18 carbon atoms and, in each case, optionally being substituted by hydroxy, and n is an integer from 18 to 30.

Abstract: In a new automated process for the selection of microorganisms, (A) agar blocks enriched with a nutrient medium are produced under sterile conditions: (B) the agar blocks are each inoculated with 1 drop of spore suspension, photometric control being used to ensure that as a rule each drop contains only one spore; (C) the inoculated blocks are kept in an incubator under conditions permitting colony formation; (D) an agar block contg. a spore colony is placed on a nutrient medium mixed with test organisms; and (E) after again keeping in an incubator, from colony diameter and zone of inhibition diameter, the index of potency is determined by computer, and selection is made on the basis of the index. Selection of strains for antibiotic prodn. or for the prodn. of other microbial prods. Efficiency is improved, so that the number of microorganisms that can be determined per unit time is increased.

Abstract: Title cpds. of formula (I) (where >=1 of R1-R3 = 3-8C oxoalkyl with the CO gp(s) one or more C's removed from the xanthine nucleus, and the others are 1-6C alkyl). may be prepd. from the corresp. hydroxy alkyl cpds. by (a) dehydrogenation with O2 and a Gp VIII metal catalyst. (b) oxidation with Cr(VI), or (c) microbiological dehydrogenation.
