What is the preferred temperature range for Pediococcus (pedio) growth?

• A. 50-70F
• B. 65-85F
• C. 70-90F
• D. 85-100F

Answer: (B)

The preferred temperature range for Pediococcus growth is indeed between 65-85°F. This range is crucial because Pediococcus is a type of lactic acid bacteria commonly used in brewing, particularly in sour beer production. They thrive in warm environments where they can efficiently ferment sugars into lactic acid, contributing to the desired sour flavors. This temperature range allows for optimal metabolic activity, where the bacteria can quickly proliferate and produce the necessary byproducts that define the character of sour beers. Temperatures outside this range may lead to slower fermentation rates or the introduction of off-flavors due to stressed organisms, which is why maintaining the appropriate temperature is vital during brewing processes that involve Pediococcus.
