  • Monitoring of Hydrogen Emission from Bacteria in Food, Animals and in the Blood of Humans Suffering from Lyme Disease by a Specific Hydrogen Sensor
    antibiotics Case Report Monitoring of Hydrogen Emission from Bacteria in Food, Animals and in the Blood of Humans Suffering from Lyme Disease by A Specific Hydrogen Sensor Bruno Kolb * , Lorina Riesterer, Anna-Maria Widenhorn and Leona Bier Student Research Centre SFZ, D-88662 Überlingen, Germany; [email protected] (L.R.); [email protected] (A.-M.W.); [email protected] (L.B.) * Correspondence: [email protected]; Tel.: +49-7551-63729 Received: 13 April 2020; Accepted: 16 July 2020; Published: 21 July 2020 Abstract: A novel straightforward analytical technique was developed to monitor the emission of hydrogen from anaerobic bacteria cultured in sealed headspace vials using a specific hydrogen sensor. The results were compared with headspace gas chromatography carried out in parallel. This technique was also applied to investigate the efficacy of chemical antibiotics and of natural compounds with antimicrobial properties. Antibiotics added to the sample cultures are apparently effective if the emission of hydrogen is suppressed, or if not, are either ineffective or the related bacteria are even resistant. The sensor approach was applied to prove bacterial contamination in food, animals, medical specimens and in ticks infected by Borrelia bacteria and their transfer to humans, thus causing Lyme disease. It is a unique advantage that the progress of an antibiotic therapy can be examined until the emission of hydrogen is finished. The described technique cannot identify the related bacteria but enables bacterial contamination by hydrogen emitting anaerobes to be recognized. The samples are incubated with the proper culture broth in closed septum vials which remain closed during the whole process.

Methanotrophs represent a widespread and 16 phylogenetically complex guild, yet the biogeography of this functional group and the factors that explain 17 the taxonomic structure of the methanotrophic assemblage are still poorly understood.
