Temperature and microbial growth

THIS POWERPOINT COVERS ABOUTMINIMUM GROWTH TEMPERATURE,MAXIMUM GROWTH TEMPERATURE, PSYCHROPHILES MESOPHILES THERMOPHILES AND HYPERTHERMOPHILES.FINALLY IT HAS A DIAGRAM SHOWING DIFFERENT TEMPERATURE RANGES OF MICROORGANISMS

1. Temperature and microbial growth Presentation by Utkarsh jain

2. INTRODUCTION MICROBES : CLASSIFIED ACCORDING TO RANGE OF TEMPERATURE THEY GROW. GROWTH RATE : HIGHEST AT OPTIMUM GROWTH TEMPERATURE. MINIMUM GROWTH TEMPERATURE : MINIMUM TEMPERATURE ORGANISM CAN SURVIVE & REPLICATE MAXIMUM GROWTH TEMPERATURE : MAXIMUM TEMPERATURE ORGANISM CAN SURVIVE & REPLICATE

3. PSCHROPHILLIC KNOWN AS PSCHROTOLERANT. PREFER COOLER ENVIRONMENT. TEMPERATURE RANGE : -20 TO 10 DEGREE CELCIUS. RESPONSIBLE FOR SPOILAGE OF REFRIGERATED FOODS. EXAMPLE : OSCILLATORIA ,ETC.

4. MESOPHILLIC ARE ADAPTED AT OPTIMUM TEMPERATURE. GROWTH TEMPERATURE RANGE : 20 TO 45 DEGREE CELCIUS EXAMPLE : LACTOBACILLUS , ETC.

5. THERMOPHILES GROWTH TEMPERATURE : 50 TO 80 DEGREE CELCIUS. DO NOT MULTIPLY AT ROOM TEMPERATURE . EXAMPLE : THERMUS AQUATICUS , ETC.

6. HYPERTHERMOPHILES GROW AT TEMPERTURE B/W 80 TO 110 DEGREE CELCIUS. EXAMPLE : PYROBOLUS , ETC.

7. GROWTH TEMPERAURES OF MICROORGANISM
