Morphological and physiological characteristics of 13 non-orange coryneforms isolated from the rinds of soft cheeses were compared with 23 coryneforms (12 soil isolates identified as arthrobacters and 22 activated-sludge isolates). The cheese strains can be differentiated from the arthrobacters mainly by their physiological features, which correlate well with differences in the amino acid and sugar compositions of the cell walls of the two groups of organisms: mesodiaminopimelic acid and arabinose are present in the cell walls of the non-orange cheese coryneforms and lysine and glucose are present in the cell walls of the soil arthrobacters. The non-orange cheese coryneforms contain corynomycolic acids, indicating a certain relationship with corynebacteria. From these and earlier studies on morphology and physiology and from hybridization experiments and deoxyribonucleic acid base composition determinations on the non-orange cheese coryneforms, it is concluded that these organisms belong to a new genus and species, for which the names Caseobacter and C. polymorphus, respectively, are proposed. Strain AC 256 is designated the type strain of C. polymorphus.Non-orange coryneform bacteria showing a pleomorphic morphology constitute an important part of the surface flora of both hard and soft cheeses. Initially, Mulder and Antheunisse (22) classified them as cheese arthrobacters from soil and noted their distinct pleomorphic morphology. However, further investigation (21) revealed that the gray-white cheese coryneforms, as well as the orange cheese coryneforms of the Brevibacterium linens type, deviate from soil arthrobacters with respect to nutritional requirements (particularly concerning nitrogen compounds and vitamins), salt tolerance, and production of polysaccharides. Furthermore, soil arthrobacters metabolize glucose more readily than do the cheese strains. The latter, however, oxidize glucose nearly completely in contrast to the soil arthrobacters, which convert about half of the glucose into reserve material, namely, glycogen. Consequently, Mulder et al. (23) concluded that gray-white cheese coryneforms should not be placed in the genus Arthrobacter, a view supported by the inability of the nonorange cheese coryneforms to decompose both urea and uric acid (3) and by the results of comparative studies on the morphological and physiological properties of both groups of coryneforms (8). The deoxyribonucleic acid (DNA) base compositions of most of the strains in the two groups are in the range of 65 to 67 mol% guanine plus cytosine (G+C), but a low degree (26%) of binding was obtained in hybridization experiments between DNA samples from representatives of both groups (7).The majority of the non-orange cheese strains tested, although isolated from different types of soft cheeses, show a nucleotide-sequence relatedness of more than 86% (7). Consequently, this group of strains belongs to one genospecies according to the criteria set forth by De Ley (12) and Brenner (5), namely, 70% or more nucleotide-sequence rela...

“…Arthrobacter strains AC1 and AC207 are able to utilize uric acid and allantoin as sole sources of carbon, nitrogen, and energy, but in contrast to A. globiformis 4 mol of ammonia is formed instead of urea (16). A. tumescens and A. simplex are uricase negative (16).…”

“…B. linens degrades both xanthine and uric acid (481). The latter substance is used as a nitrogen source (481) but not as a nitrogen and carbon source (16). Washed cells convert 1 mol of uric acid or allantoin to 1 mol of urea (16).…”

“…Specifically, the most complex, recalcitrant compounds (nucleic acids, peptidoglycan, and humics) were generally used poorly in comparison to other substrates. The crystalline and polymerized forms of these compounds makes them refractory to enzymatic degradation although degradation of humic matter [48], nucleic acids [49], and peptidoglycan [36] occurs under certain growth conditions. Thus, the observed low utilization of these recalcitrant substrates relative to the labile substrates may be a function of the minimal media conditions used in the substrate assay in this study.…”

Initial nitrogen enrichment conditions determines variations in nitrogen substrate utilization by heterotrophic bacterial isolates

et al. 2017

BackgroundThe nitrogen (N) cycle consists of complex microbe-mediated transformations driven by a variety of factors, including diversity and concentrations of N compounds. In this study, we examined taxonomic diversity and N substrate utilization by heterotrophic bacteria isolated from streams under complex and simple N-enrichment conditions.ResultsDiversity estimates differed among isolates from the enrichments, but no significant composition were detected. Substrate utilization and substrate range of bacterial assemblages differed within and among enrichments types, and not simply between simple and complex N-enrichments.ConclusionsN substrate use patterns differed between isolates from some complex and simple N-enrichments while others were unexpectedly similar. Taxonomic composition of isolates did not differ among enrichments and was unrelated to N use suggesting strong functional redundancy. Ultimately, our results imply that the available N pool influences physiology and selects for bacteria with various abilities that are unrelated to their taxonomic affiliation.Electronic supplementary materialThe online version of this article (doi:10.1186/s12866-017-0993-7) contains supplementary material, which is available to authorized users.
