446:. This process causes the pH of the reaction to increase 1–2 pH, making the environment more basic which promotes the conditions that this specific bacterium thrives in. Maintaining a medium with this pH can be expensive for large scale production of this bacterium for biocementation. A wide range of factors can affect the growth rate of
712:. A lack of oxygen also prevents MICP since its initiation relies heavily on oxygen. Therefore, at sites distant from the injection location or at great depths, the likelihood of precipitation decreases. One potential fix is to couple this bacterium in the biocement with oxygen releasing compounds (ORCs) that are typically used for

Concrete is one of the most used materials in the world but it is susceptible to forming cracks which can be costly to fix. One solution is to embed this bacterium in the cracks and once it is activated using MICP. Minerals will form and repair the gap in a permanent environmentally-friendly way. One
