Question

Lactic acid bacteria such as Lactococcus A. produce catalase.B. are obligate fermenters.C. require anaerobic environments.D. use oxygen as a final electron acceptor.

Answer 1

are obligate fermenters

Step-by-step explanation:

• An obligate fermenter is an organism that is only able to survive via fermentation is not capable of aerobic respiration.
• Lactic acid bacteria are gram-positive bacteria that can either be rod-shaped or spherical.
• These bacteria are capable of carbohydrate fermentation and the end product of this process of fermentation is lactic acid.
• Lactococcus is one such genus of the lactic acid bacteria that is an obligate fermenter. They can ferment glucose and the only product that is produced as a result of fermentation is lactic acid.
• Lactococcus are commonly used in the cheese industries to ferment dairy products.
