MCB 3020L Lecture Notes - Lecture 50: Thickening Agent, Gel, Biofilm
Document Summary
Complex polymer contianing many time its dry weight in water. Reside in a matrix made up primarily of polysacchardies. Cell-to cell chemical communication that allows bcteria to coordinate their activity and group together into communities that provide benefits not unlike those of multi cellular orgnaisms. Sheltered from dessication, antibiotics, and the body"s immune system, share helpful genetic information via conjugation. When a free swimming (planktonic) bacerium attaches to its surface. They are probably 1000x more resistant to microbicides. Nutrient material prepared for the growth of microorganisms in a laboratory. Microbes that are introduced into a culture medium to initiate growth. Microbes that grow and multiply in or on a culture medium. Thickener in food that is typically used as a solid medium to allow bacteria to grow. Agar are grown in petri or culture plates. A medium who exact chemical composition is known.
