Preparation of Agar Plates Growth and Check of Bacterial Strains. Bacteria can be propagated on liquid or solid media. The use of liquid allows large quantities of bacteria to be harvested but does not permit easy selection or determination of phenotype of single cells.
Nutrient Agar: Composition, Preparation and Uses Last updated: September 27, 2018 by Sagar Aryal Nutrient Agar is a general purpose, nutrient medium used for the cultivation of microbes supporting growth of a wide range of non-fastidious organisms.
Protocol Preparation of X-Gal/IPTG LB Agar Plates for Blue/White Colony Screening For individual LB (Luria Broth) agar plates: 1. Pour sterile warm LB agar (about 25 mL) into a Petri dish.
This video will show you how to weigh out and prepare your LB agar media ready to sterilize using the autoclave.
The method for the preparation of basic microbiology media is given below. In situations where preparation is uneconomic in time, prepared, sterilized media (liquid and solid) are available from the major school science equipment suppliers. Sterilization is at 121 °C (15 lb in ˉ²) for 15 minutes. pH values are 7.0 unless stated otherwise.
PREPARATION OF MEDIA I. OBJECTIVES • To become familiar with the necessary nutritional and environmental factors for culturing microorganisms in the laboratory. • To understand the decontamination or sterilization process using an autoclave. • To learn the procedures used in preparing media needed for culturing microorganisms. II.
The acronym has been variously interpreted, perhaps flatteringly, but incorrectly, as Luria broth, Lennox broth, or Luria Bertani medium. For the historical record, the abbreviation LB was intended to stand for "lysogeny broth." (5, page 598). Preparation. The following is a common method for the preparation of 1 litre of LB:
Lysogeny broth (LB) is a nutritionally rich medium primarily used for the growth of bacteria.Its creator, Giuseppe Bertani, intended LB to stand for lysogeny broth, but LB has also come to be commonly referred to as Luria broth, Lennox broth, or Luria-Bertani medium.

Preparation of 1000 ml LB (Luria-Bertani), Miller broth; Preparation. Step 1: To prepare 1000 ml of Lennox LB broth, weigh out 10 grams tryptone, 5 grams yeast extract and 10 grams sodium chloride in 2 litre conical flask / beaker. Add 800 ml deionized/Milli-Q water. Mix it. Solution will appear translucent yellowish with undissolved media ...
About LB agar plates. Luria-Bertani (LB) agar plates are nutrient-rich plates used for growing bacteria on. They are commonly used during cloning experiments to amplify antibiotic-resistant, competent bacteria. The same components, excluding agar, can be used to create a liquid LB media.

For 2X-LB agar plate preparation: Add 7.5 g Bacto agar per 500 mL of 2´-LB. Autoclave on liquid cycle (45 min sterilization time). Let cool to ~55°C in water bath. Add carbenicillin to 100 µg/mL (1:1,000 from stock) and pour plates (1 sleeve of 20 plates from 500 mL 2´-LB/agar solution).
Lysogeny Broth (LB) Agar & Neurospora Agar Preparation Protocol (2017) 1. To make 200 mL of LB agar weigh out the following into an appropriate size media bottle: 2g NaCl 2g Tryptone 1g Yeast Extract 3g Agar and (dH 2 O) to 200mL The recipe makes 10 (11 cm) petri dishes. Adjust amounts accordingly to suit your needs.
11. Let agar cool to ~55C (you should be able to pick up the jar without a glove) 12. Add Ampicillin to cooled LB agar (500ul – 1:100 of 100ug/ml stock). ! Pouring the Plates 1. Make sure the hood is wiped down with bleach/EtOH. 2. Remove sterile Petri dishes from plastic bag (save the bag for storage). 3.
LB agar. Agar (20 g/L) NaCl (10 g/L; Sigma-Aldrich S9625) Tryptone (10 g/L; BD 211705) Yeast extract (5 g/L; BD 212750) Add H 2 O to a final volume of 1 L. Adjust the pH to 7.0 with 5 N NaOH.
Agar (Autoclave) Media Preparation Protocol (Biotech Series) 1. LB Agar Recipe- weigh out the following into 500 mL media bottles: 2g NaCl 2g Tryptone 1g Yeast Extract 3g Agar and (dH 2 O) to 200mL The recipe makes 10 (11 cm) petri dishes. Adjust amounts accordingly to suit your needs.
Luria broth (LB) is a nutrient-rich media commonly used to culture bacteria in the lab. The addition of agar to LB results in the formation of a gel that bacteria can grow on, as they are unable to digest the agar but can gather nutrition from the LB within.
For 500 mL of LB Agar, add 500 uL of each antibiotic needed. 8. Swirl to mix, use pipette to transfer 20 mL into each plate or simply pour it carefully in the plate . Try to the formation of bubbles. *** 9. Allow plates to cool and solidify. Mark antibiotic on side of plate. If LB Agar solidifies before being poured, microwave to liquefy again ...
LB Agar Preparation: As a class, transfer the LB Agar to a 250r 300ml flask. Add 150ml distilled water and tightly cover the flask mouth with aluminum foil, similar plug or lose cap. 4. Autoclave the LB Broth and LB Agar for 15min at 121qC. Turn the autoclave off.
This protocol is adapted from Sambrook & Russell for the preparation of Luria-Bertani medium. It describes preparation of both liquid and 1.5% solid agar media. Sambrook, J. & Russell, D. W. (2001). Molecular Cloning: A Laboratory Manual, 3 edn. Cold Spring Harbor, N.Y.: Cold Spring Harbor Laboratory Press. pp. A2.2
Lysogeny broth (LB), more commonly called Luria Broth, agar plates are typically used as a growth substrate for the culture of bacteria (e.g., E. Coli). Selective growth compounds may also be added to the media, such as antibiotics.
Streak the cells on a plate with LB agar and incubate overnight at 37ºC. D a y 2 Preculture: pick an isolated colony from the plate and inoculate 50 ml of LB with it. Incubate overnight at 37ºC shaking the culture at 150-250 rpm. D a y 3 1. Use 0.5 ml of fresh, overnight E. coli culture grown in LB to inoculate 50 ml ZymoBroth™
3. Pour a thin layer (5mm) of LB Agar (~10mL) into each plate being careful to not lift the cover off excessively (you should be able to just open up enough to pour). 4. Swirl plate in a circular motion to distribute agar on bottom completely. 5. Let each plate cool until its solid (~20 minutes) then flip so as to avoid condensation on the agar. 6.
