This document provides instructions for preparing and sterilizing microbiological media including tryptic soy broth (TSB) and tryptic soy agar (TSA). Key steps include: 1) Making TSB by dissolving powder in water and distributing to test tubes, then making TSA by adding agar powder to remaining TSB and pouring plates or pipetting into slants. 2) Autoclaving prepared media at 121°C for 15 minutes to sterilize, ensuring a 100% kill of microbes. 3) Distributing sterilized media in different formats like slants, which are tilted after sterilization to solidify agar at an angle.
