| Description | One of the key aims of the project was to understand how the metabolic activity of bacteria is linked to the formation of biominerals. We have now studied one bacterium in much greater detail than was done before and can now link its consumption of a particular nutrient to how much calcium carbonate it produces. Calcium carbonate, in the form of the mineral calcite, is the main component of limestone. |
| Exploitation Route | With our new understanding, we will now be able to optimise calcite formation to develop sustainable construction materials, with the aim of using bacterial mineral formation instead of cement. Upon publication, the new bacterium will be made available to other researchers to maximise its use and potential impact. |

| Title | Dataset for "Air-entraining admixtures as a protection method for bacterial spores in self-healing cementitious composites: Healing evaluation of early and later-age cracks" |
| Description | This dataset contains the experimental results obtained when evaluating the feasibility of using air-entraining agents (AEAs) as an economical and straightforward encapsulation method for bacterial spores in bacteria-based self-healing cementitious materials when cracks (~ 0.50 mm) are formed at an early (28 days) or later age (9 months). The data included here corresponds to the following test methods: 1) Determination of air-content (BS EN 1015-7 (Method A- Pressure method)). 2) Flowability (BS EN 1015-3). 3) Compressive and flexural strength of mortar specimens (BS EN 1015-11). 4) Images and data used for determining the mean healing ratio of the complete cracks using image binarization. 5) Crack healing (%) as a function of the initial crack width for mortar specimens cracked after 28-days or 9-months of curing. 6) Improvement in water penetration resistance following RILEM test method 11.4. 7) Raman spectroscopy for 9-months-old mortar specimens after a healing period of 56 days. 8) Images and data used for determining the micro-bubbles total area and size distribution. |
