    • A microbiological process for the preparation of N,N'-ethylenediaminedisuccinic acid of formula (1), by (a) precultivation of a strain of the genus Amycolatopsis orientalis on a specified nutrient medium (1st preculture), (b) inoculation of a nutrient solution of the same composition as the base of the production fermenter by the 1st preculture (2nd preculture), (c) inoculation of the base nutrient solution in the production fermenter with the 2nd preculture and incubation in accordance with a specified timetable, (d) feeding of the production fermenter in the fed-batch process with a feeding solution under aerobic conditions at a pH of from 2 to 8 and at a temperature of from 15.degree. to 40.degree. C., wherein the base nutrient and feeding solutions are free of zinc-containing compounds, is described. The compound prepared by the process according to the invention is suitable as complexing agent with good biodegradability in detergents. ##STR1##

    • A method of combating arthropods, comprising applying to the arthropods, or to a habitat infested therewith an arthropodicidally effective amount of an antibiotic which (a) is colorless, very readily soluble in water and in pyridine but insoluble in other customary organic solvents, gives a positive reaction with ninhydrin, sodium metaperiodate/benzidine and potassium permanganate and gives a yellow coloration with iron (III) chloride, (b) has the UV and IR spectra substantially as shown in FIGS. 1 and 2, (c) on chemical degradation yields uracil, an amino-hexuronic acid and an amino-acid containing a pyridine ring, (d) on paper electrophoresis proves to be an amphoteric substance and has an isoelectric point at about pH 6 and (e) consists of the elements carbon, hydrogen, oxygen and nitrogen, or one or more active components of the antibiotic mixture, the active agent being applied alone or in admixture with a diluent or carrier. The antibiotic is known as Nikkomycin which is apparently a mixture of components of the formula ##STR1## in which R.sub.1 is ##STR2## and R.sub.2 is hydrogen, ##STR3##
