Bacteria are often social creatures. Suspended in colonies of varying shapes and sizes, these microbes communicate with their brethren and even other bacterial species - interactions that can sometimes make them more deadly or more resistant to antibiotics.
Now, bacterial colonies sculpted into custom shapes by a 3-D printer could be a key to understanding how some antibiotic-resistant infections develop. The new technique uses methods similar to those employed by commercial 3-D printers, which extrude plastic, to create gelatin-based bacterial breeding grounds. These microbial condos can be carved into almost any three-dimensional shape, including pyramids and nested spheres.
Suspending a life in time is a theme that normally finds itself in the pages of science fiction, but now such ideas have become a reality in the annals of science.
Enzymes in cleaner contains hydrolase such as protease, lipase and diastase, which can decompose protein, carbohydrate and lipids into the constituent having relative small formula weight like peptide segments, delspray and oligosaccharide so that the solubility and suspending power of aqueous solution are stronger, improving the cleaning effect. Enzymes in cleaner is applicable to decompose the protein besmirch such as milk, bloodstain and food residue;
