Overview

Harry J. Flint is affiliated with the University of Aberdeen in the United Kingdom. Their research spans several interconnected fields with a focus on gut microbiota and associated metabolic processes.

The main fields of study covered by Flint include Biochemistry, Genetics and Molecular Biology, Medicine, and Agricultural and Biological Sciences. Within these broader areas, their work often addresses Molecular Biology, Physiology, Food Science, Nutrition and Dietetics, and Genetics as sub-disciplines.

Key topics of research for Flint encompass gut microbiota and health, diet and metabolism studies, probiotics and fermented foods, as well as specific bacterial research related to Clostridium difficile and Clostridium perfringens. Additional interests include nutritional studies and diet, microbial metabolites in food biotechnology, and microbial metabolic engineering and bioproduction.

Flint has published in several recurring venues, reflecting the thematic focus and interdisciplinary nature of their work. Frequent publication venues include Gut Microbiome, Environmental Microbiology, ESMO Open, mBio, and mSystems.

Notable recent papers by Flint demonstrate a focus on microbial activity and ecology within the human gut:

  • "Vitamin Biosynthesis by Human Gut Butyrate-Producing Bacteria and Cross-Feeding in Synthetic Microbial Communities" (2020) in mBio
  • "Pivotal Roles for pH, Lactate, and Lactate-Utilizing Bacteria in the Stability of a Human Colonic Microbial Ecosystem" (2020) in mSystems
  • "Microbial lactate utilisation and the stability of the gut microbiome" (2022) in Gut Microbiome
  • "Relative abundance of the Prevotella genus within the human gut microbiota of elderly volunteers determines the inter-individual responses to dietary supplementation with wheat bran arabinoxylan-oligosaccharides" (2020) in BMC Microbiology
  • "β-Glucan is a major growth substrate for human gut bacteria related to Coprococcus eutactus" (2020) in Environmental Microbiology

Flint has also contributed to book publications, including the title Why Gut Microbes Matter, published by Springer International Publishing in 2020.

Collaboration is a visible aspect of Flint's efforts, with frequent co-authors including Sylvia H. Duncan, Petra Louis, Alan W. Walker, Freda M. Farquharson, and Graham Horgan. These partnerships underline the collaborative and multidisciplinary approach in their research activities.
