“…Two oxalate-utilizing Streptomyces (S. violaceus and S. rochei) that are reported here have previously been reported to utilize calcium oxalate (Robbel and Kutzner 1973;Knutson et al 1980). S. rochei was the most frequently isolated oxalate-utilizing Streptomyces species, comprising half of all isolates, and similar findings were noted by Knutson et al (1980).…”

“…The oxalate-utilizing strains seem to be diverse at the species level and S. rochei is in a dominant position. Robbel and Kutzner (1973) and Knutson et al (1980) found that oxalate and malonate are useful substrates for the differentiation of Streptomyces species. This study agrees that utilization of organic acids is a valuable taxonomic aid for identifying Streptomyces species.…”

“…Because of the similarity between species in chemotaxonomic characters, numerical taxonomic studies have been very important to the taxonomy of streptomycetes. Although several isolations have described streptomycetes around the world, little attention has been paid to their consumption of organic acids as a diagnostic criterion (Khambata and Bhat 1954;Nitsch and Kutzner 1969;Robbel and Kutzner 1973;Knutson et al 1980) and there are no comprehensive and specific published data available on the properties of these physiological groups of microbial communities. During the last two decades some valuable information on the oxalate-utilizing organisms -mostly bacteria (except Actinobacteria) -has been published and reviewed from a taxonomic point of view (Sahin 2003).…”

The present work was aimed at the isolation of additional new pure cultures of oxalate-degrading Streptomyces and its preliminary characterization for further work in the field of oxalate metabolism and taxonomic studies. Mesophilic, oxalate-degrading Streptomyces were enriched and isolated from plant rhizosphere and forest soil samples. Strains were examined for cultural, morphological (spore chain morphology, spore mass colour, diffusible and melanin pigment production), physiological (antibiosis, growth in the presence of inhibitory compounds, assimilation of organic acids and enzyme substrates) and chemotaxonomic characters (cellular lipid components and diagnostic cell-wall diamino acid). The taxonomic data obtained were analysed by using the simple matching (SSM) and Jaccard (Sj) coefficients, clustering was achieved using the UPGMA algorithm. All strains were able to utilize sodium-, potassium-, calcium- and ammonium-oxalate salts. Based on the results of numerical taxonomy, isolates were grouped into five cluster groups with a > or =70% S(SM) similarity level. Streptomyces rochei was the most common of the cluster groups, with a Willcox probability of P > 0.8. Streptomyces antibioticus, S. anulatus, S. fulvissimus, S. halstedii and S. violaceusniger are newly reported as oxalate-utilizing Streptomyces.

“…The biological degradation of oxalate is in agreement with the fact that accumulation of metal oxalates has not been observed in geological records (Schilling & Jellison, 2004; Verrecchia et al ., 2006), except in some very specific settings such as hydrothermal springs (Hofmann & Bernasconi, 1998) and septarian concretions (Hyde & Landy, 1966). Normally, a microbiologically mediated process is assumed to be the main oxalate degradation process in natural environments, leading to the precipitation of calcium carbonate or other forms of carbonate depending on the oxalate mineral sources (Robbel & Kutzner, 1973).…”

Isothermal microcalorimetry (IMC) has been used in the past to monitor metabolic activities in living systems. A few studies have used it on ecological research. In this study, IMC was used to monitor oxalotrophic activity, a widespread bacterial metabolism found in the environment, and particularly in soils. Six model strains were inoculated in solid angle media with K-oxalate as the sole carbon source. Cupriavidus oxalaticus, Cupriavidus necator, and Streptomyces violaceoruber presented the highest activity (91, 40, and 55 μW, respectively) and a maximum growth rate (μmax h(-1) ) of 0.264, 0.185, and 0.199, respectively, among the strains tested. These three strains were selected to test the incidence of different oxalate sources (Ca, Cu, and Fe-oxalate salts) in the metabolic activity. The highest activity was obtained in Ca-oxalate for C. oxalaticus. Similar experiments were carried out with a model soil to test whether this approach can be used to measure oxalotrophic activity in field samples. Although measuring oxalotrophic activity in a soil was challenging, there was a clear effect of the amendment with oxalate on the metabolic activity measured in soil. The correlation between heat flow and growth suggests that IMC analysis is a powerful method to monitor bacterial oxalotrophic activity.
