Strains of the bacterium Pseudomonas syringae have been identified as being capable of _______.
a. Producing plastics
b. Producing alternative fuels
c. Fermenting foods
d. Preventing ice formation

검증된 단계별 안내

Understand the context of the bacterium Pseudomonas syringae and its unique biological properties.

Recall that Pseudomonas syringae is known for its role in influencing ice formation due to specific proteins it produces.

Recognize that these ice nucleation proteins can catalyze ice formation at relatively high subzero temperatures, which is a distinctive feature of this bacterium.

Compare the options given: producing plastics, producing alternative fuels, fermenting foods, and preventing ice formation.

Conclude that the correct capability of Pseudomonas syringae is related to ice formation, specifically that it promotes ice nucleation rather than preventing it.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Pseudomonas syringae Characteristics

Pseudomonas syringae is a common plant-pathogenic bacterium known for its ice nucleation activity. It produces proteins on its surface that promote ice crystal formation at relatively high subzero temperatures, influencing frost damage in plants.

Ice Nucleation Activity

Ice nucleation activity refers to the ability of certain bacteria, like Pseudomonas syringae, to catalyze ice formation by providing a template for water molecules to freeze. This property is unique and has applications in weather modification and frost prevention.

Biotechnological Applications of Bacteria

Bacteria can be harnessed for various biotechnological uses, such as producing bioplastics, biofuels, or fermenting foods. However, Pseudomonas syringae is specifically notable for its role in ice nucleation rather than these other applications.
