The growth of bacteria was tracked over an incubation period of six hours. ... Our team ensures the antimicrobial fabric treatments work within the constructs of your existing processes for minimal disruption and seamless integration from lab to mill to final fabric performance. Microbial cell paste or prechopped tissue, a minimum volume of buffer and 0.5-1 volume of grinding media is mixed and ground with a mortar and pestle. Disruption efficiency is poor if too much media is added or smaller charges of grinding media are used.

The TissueLyser LT provides effective disruption of human, animal, and plant tissues, bacteria, and yeast, allowing reproducible yields of DNA, RNA, and protein in subsequent purification procedures (see figure "Effective tissue disruption"). Even difficult-to-lyse tissues such as heart and brain can be processed by the TissueLyser LT. The NucleoSpin Microbial DNA kit utilizes MN Bead Tubes Type B (glass beads; included in the kit) in combination with Liquid Proteinase K, and a common disruption device e.g., swing mill, in order to lyse different sample materials with one procedure.
