Question
Please help answer questions 1 (just the second part of the question, the part about bacteriostatic ) and Question 2 based on the results in the second picture.Please help complete this lab report questions Just need help answering questions 1-2 based of the results obtained in the 2nd picture. Bioactivity of Food 1- Label your LB Agar plates into 4 equal parts as above 2- Swab, spread with jockey stick or beads the test bacteria on all the surface of the plate. 3-Aler swabbing the agar plate, place the various food items made available. Use steile forceps to maneuver the food items gently onto the agar surface Incubate the plate at 30 "C for 48 hours. S- Next week, measure the size of the zones of inhibition in millimeters (mm) if any and record your observations in your worksheet. Results: Directions: Place the zone of inhibition (if any) in response to food products including onion, garlic, and pepper in millimeters 1- Which of the food products was the most effective against the bacteria tested? Is the action of the food itm bacteriostatic or bactericidal? How can you prove a compound is bacteriostatic? 2- How can the information obtained from the food bioactivity assay be applied or be useful into your daily life? These are the results of the lab Enteroccocus rafinsu Food Prtcluct 2ne Of Inhlb ND Staphyloccuus epider micus ND Gai lic Pe
Explanation / Answer
1. Garlic was most effective against the Staphylococcus epidermidis. Because it shows zone of inhibition of about 18mm. This test used clinically to measure antibiotic resistance.
The action of food item is bateriostatic. Bacteriostatic means these agents are used to limit the growth and reproduction of microorganisms by interfering with their protein production, DNA replication, or other aspects of bacterial cellular metabolism, that means it resist bacteria, not kill them.
As the test used to measure antibiotic resistance, so the action of food item is bateriostatic.
2. Food bioactivity really useful into our daily life because bioactive molecules modulate one or more metabolic processes which promote better health. These are predominantly found in plant foods such as whole grains, fruit, and vegetables. These molecules found in multiple forms such as glycosylated, esterified, thiolyated, or hydroxylated. Metabolic activities of bioactive food component allows beneficial effects in several diseases and target tissues.
