“…Several aldehydes, including methyl butanal, were observed in the headspace of the blank MHB liquid media and their concentrations decreased in the headspace of bacterial cultures; thus, they are not included in tables 2 and 3. This removal of aldehydes from culture media by bacterial and some mammalian cells has been observed in previous studies [29][30][31][32].…”

Stenotrophomonas rhizophila (n=2) cultured in Mueller-Hinton Broth (MHB) liquid media were analysed by gas chromatography mass spectrometry (GC-MS) and selected ion flow tube mass spectrometry (SIFT-MS). Several VOCs were detected in high concentration, including ammonia, propanol, dimethyl disulphide, and dimethyl trisulphide. The GC-MS measurements showed that all 15 clinical strains produced similar headspace VOCs compositions and SIFT-MS quantification showed that the rates of production of the VOCs by the genotypically distinct strains were very similar. All in vitro cultures of both the Stenotrophomonas species were characterised by efficient production of two isomers of methyl butanol, which can be described by known biochemical pathways and which is absent in other pathogens including Pseudomonas Aeruginosa . These in-vitro data indicate that methyl butanol isomers may be exhaled breath biomarkers of S. maltophilia lung infection in patients with cystic fibrosis.

1995. T h e growth in glucose media of many heterofermentative lactic acid bacteria is greatly improved by the provision of an ancillary oxidant which serves as a terminal electron sink. Lactobacillus brevis is representative of those organisms for which dioxygen is preferentially used for this purpose. Here the authors report that some other species including Lact. hilgardii, Lact. suebicus and Lact. vaccinostercus do not utilize dioxygen in this manner and consequently are able to catalyse bioreductions (e.g. of ketones) under aerobic culture conditions or in aerated cell suspension. T h e explanation for this lies in the NADP-dependence of their glucose &-phosphate and 6-phosphogluconate dehydrogenases plus the total or near absence of any NADPH oxidase activity. Lactobacillus hilgardii possesses virtually no NADH oxidase activity, and although both Lact. suebicus and Lact. vaccinostercus inducibly synthesize a NADH oxidase, in the absence of an auxiliary oxidant they still grow aerobically on glucose as poorly as they do anaerobically.
