Tuning Microbial Surfaces to Control Carbonate Mineralization

Cyanobacteria as Biocatalysts for Carbonate Mineralization

Microbial carbonate mineralization is widespread in nature and among microorganisms, and of vast ecological and geological importance. However, our understanding of the mechanisms that trigger and control processes such as calcification, i.e., mineralization of CO2 to calcium carbonate (CaCO3), is limited and literature on cyanobacterial calcification is oftentimes bewildering and occasionally ...

Microbial Attachment to Meat Surfaces

The attachment of microorganisms to various surfaces and the mechanisms of attachment have become of great interest to the food industry and to researchers during the past decade. Few things have a closer relationship to man than the many bacteria, yeasts and molds that we constantly contact in our food sources and environment. A large group of these organisms is considered as beneficial; they ...

Geochemical Characterization of Sulfide Mineralization in Eastern Wisconsin Carbonate Rocks

Iron oxyhydroxide mineralization on microbial extracellular polysaccharides

Iron biominerals can form in neutral pH microaerophilic environments where microbes both catalyze iron oxidation and create polymers that localize mineral precipitation. In order to classify the microbial polymers that influence FeOOH mineralogy, we studied the organic and mineral components of biominerals using scanning transmission X-ray microscopy (STXM), micro X-ray fluorescence (lXRF) micr...

Primary mineralization at the surfaces of implants.

Osteogenesis around implants is affected by the physical and chemical characteristics of the biomaterials used. The osteoprogenitor cells must migrate to the implant site and synthesize and secrete a mineralizable extracellular matrix. Because this is neo-bone formation, the mechanism by which the cells calcify their matrix involves extracellular organelles called matrix vesicles in a process t...
