Microbiology

Our strengths in environmental microbiology and microbial evolution are complemented with expertise in microbial DNA metabolism and synthetic biology, allowing us to develop projects pertinent to industrial biotechnology and bioenergy. 

Our research in fundamental and applied disease-related mechanistic microbiology has resulted both in novel therapeutic drug leads and in cancer gene therapy approaches.‌

Work within the microbiology research focus has impact across all three grand challenges but particularly on human health and disease as well as environmental change.  These are just a few examples

Examples of Microbiology research

New light on DNA copying process: Peter McGlynn, an Anniversary Professor in the University’s Department of Biology, led a team of researchers who have discovered that the protein machines that copy DNA in a model organism pause frequently during this copying process, creating the potential for dangerous mutations to develop.

Targets for aphid-specific insecticides: aphids use a symbiont, Buchnera, that lives inside specialised bacteriocyte cells in the insect gut to supplement their diet of sugary sap.  Using computational modelling of the bacteriocyte metabolism, York researchers led by Gavin Thomas showed that it is the insect cells rather than the bacteria that recycle nitrogen to build essential amino acids, thus providing potential targets for aphid-specific pesticides.

TRAP transporters in Vibrio cholerae: The bacterium Vibrio cholerae colonises the intestine and causes a diarrhoea that can be fatal. Important to its survival is harvesting of sialic acid present on the surface of gut cells.  York researchers demonstrated that the pathogen uses a TRAP transporter to scavenge and take up sialic acid, a discovery that may enable design of drugs to treat V. cholerae infections.‌
