There are many variations of the recipe for LB broth but the most common is as follows: combine 10 g of tryptone, 5 g of yeast extract, 10 g of NaCl, and 1 liter of distilled water; adjust the pH to 7.0 with 1 N NaOH; and autoclave the mixture for 25 minutes at 120°C . Just about every lab must sterilize some type of liquid solution, such as lysogeny broth (otherwise known as LB Broth), media, agar, buffer, saline, and water. And as such, sterilization of a liquid in a vented container requires a special type and the proper application of a cycle known as the Liquids Cycle. The Liquids Cycle* Strictly speaking, LB agar should be call ed LA. LB Variations Variations of the LB recipe can be found in the literature and lab manuals. One variation of LB ("Lennox Broth"), calls for the use of 5 grams per liter of NaCl (Lennox, 1955; Gerhardt, et al. 1994).

However, can a sterile filter(ex; 0.2 um) be used instead if the autoclave isn't available?
The autoclave operator can calculate a lower cycle time for sterilizing the liquid based on the Fo (F Zero) empirical tables. If a normal sterilization holding time is set to 15 minutes, it may be reduced by seconds/minutes based on the Fo calculation. This will help prevent overcooking the liquid while still ensuring proper sterilization.Why do you want to microwave it instead of autoclaving? It takes < 1 hour to make up and autoclave a supply of LB that will last 3-6 months. Most of that time is hands-off, just waiting for the autoclave cycle to complete. I actually think it would be significantly more annoying to rely on microwaving LB, since you'd have to boil it batch by batch.
