OBSERVATIONS ON THE GROWTH AND MOVEMENT OF ACINETOBACTER ON SEMI-SOLID MEDIA Barker, J. and Maxted, Heather,, 8, 443-446 (1975), doi = https://doi.org/10.1099/00222615-8-3-443, publicationName = Microbiology Society, issn = 0022-2615, abstract= SUMMARY The growth of 29 strains of Acinetobacter spp. on semi-solid media was studied; 19 showed surface swarming and 14 produced channels (“ditches”) in the agar that do not seem to have been described previously. An attempt was made to define the cultural and physical conditions for the demonstration of these phenomena. Possible taxonomic implications are discussed., language=, type=
