Q1. Lactic Acid Fermentation Is The Most Effective Strategy For?
A) Increasing The Quantity Of Food
B) Preparation Of Brown Bread
C) Food Preservation
D) Production Of Beer
ANSWER – C) Food Preservation
- During The Fermentation Process, Lactic Acid Bacteria (LAB) Produces Anti-Microbial Metabolites, Include Organic Acids Like Propionic, Acetic Acid, And Lactic Acids As Final Products. They Create An Unfavorable Environment For Spoilage And Pathogenic Microorganism’s Growth.

Q2. Which Of The Following Are The Heterofermentative Bacterial Species?
A) Lueconostac Spp.
B) Enterococcus Spp.
C) Pedococcus Spp.
D) Streptococcus Spp.
ANSWER – A) Lueconostac Spp.
- Heterofermentive Is Producing A Fermentation Resulting In A Number Of End Products. Heterofermentative Bacteria Produce Less Lactate And Less ATP But Produce Several Other End Products: Glucose + ADP + Pi → Lactate + Ethanol + CO2 + ATP. Other Examples Include Leuconostoc Mesenteroides, Lactobacillus Bifermentous, And Leconostoc Lactis.

Q3. The Primary Fermentation Is Carried Out At The Temperature Of?
A) 10-20°C
B) 20-30°C
C) 15-25°C
D) 40-50°C
ANSWER – A) 10-20°C
-
The Primary Fermentation Is Carried Out At The Temperature Of 10-20°C. Temperature Plays A Critical Role In Fermentation. Yeast Needs To Be Warm Enough To Be Healthy, But Too Warm Will Stress The Yeast. Too Cool And The Yeast Will Be Sluggish And Sleepy. As Temperature Increases, The Fermentation Rate Accelerates.
