What is the optimum pH range for bacterial growth?
H-ion Concentration • pH range, optimum pH • Neutral or slightly alkaline pH (7.2 – 7.6) – majority of pathogenic bacteria grow best. • Lactobacilli – acidic pH • Vibrio cholerae – alkaline pH 25. Moisture and drying • Water – essential ingredient of bacterial protoplasm. Hence drying is lethal to cells.
How are bacteria classified based on nutrition?
IT’S THE GROWTH, NU TRITION AND METABOLISM 8. Classification • Based on Nutrition bacteria are classified as : 1. Autotrophs – can synthesise all their organic compounds by utilising atmospheric CO2 & N2. No medical importance. 2. Heterotrophs – unable to synthesise their own metabolites & depend on preformed organic compounds. All pathogens
What is the pH of lactobacilli?
• Lactobacilli – acidic pH • Vibrio cholerae – alkaline pH 25. Moisture and drying • Water – essential ingredient of bacterial protoplasm. Hence drying is lethal to cells. • Effect of drying varies : T.pallidum – highly sensitive Staphylococcus spp– stand for months • Spores – resistant to dessication, may survive for several decades
What is the best temperature to grow bacteria?
CLASSIFICATION BASED ON TEMP • Mesophilic – grows best between 25ºC and 40ºC. e.g. most bacterial pathogens • Psychrophilic (cold loving) – grows best below 20ºC e.g. Flavobacterium spps • Thermophilic – grows best at high temp, 55- 80ºC e.g. Bacillus sterothermophilus 21.
