NTCC? Pseudoalteromonas antarctica strain NF3

Classification: It is a psychrotolerant (cold-tolerant) marine bacterium belonging to the genus Pseudoalteromonas.

Origin: The strain NF3 was isolated from a coastal marine environment in Antarctica, specifically from the South Shetland Islands.

Key Characteristics: This bacterium is notable for its ability to survive in extreme cold environments. A significant feature is its production of a large amount of an extracellular polymeric substance (EPS), which is a slimy, protective material with a high protein content. This EPS is thought to play a vital role in the bacterium's survival in the harsh Antarctic environment.

Research Interest: Scientists study this strain to understand how it adapts to its cold, nutrient-poor habitat. The EPS it produces is of particular interest as a potential source of novel, cold-adapted proteins and other biomolecules with possible industrial or biotechnological applications.

The NTCC strain NF3 is also referred to by its culture collection numbers, such as LMG 18002 and CECT 4664

南極假交替單胞菌NF3（英文名：Pseudoalteromonas antarctica strain NF3）是一種生活在極地環(huán)境中的海洋細(xì)菌。

• 分類: 它屬于假交替單胞菌屬，是一種耐冷的海洋細(xì)菌。

• 來源: NF3菌株是從南極洲南設(shè)得蘭群島沿海地區(qū)的海洋環(huán)境中分離出來的。

• 主要特性: 這種細(xì)菌最顯著的特點(diǎn)是能在極端寒冷的環(huán)境中生存。它能產(chǎn)生大量胞外聚合物（EPS），這是一種高蛋白含量的粘性保護(hù)物質(zhì)。這種EPS被認(rèn)為對(duì)細(xì)菌在嚴(yán)酷的南極環(huán)境中生存至關(guān)重要。

• 研究?jī)r(jià)值: 科學(xué)家們研究該菌株，是為了了解它如何適應(yīng)寒冷、貧瘠的棲息地。其產(chǎn)生的EPS尤其具有研究?jī)r(jià)值，被認(rèn)為是新型耐寒蛋白質(zhì)和其他生物分子的潛在來源，可能在工業(yè)或生物技術(shù)領(lǐng)域有應(yīng)用前景。

NTCC's NF3菌株在菌種庫(kù)中也有對(duì)應(yīng)的編號(hào)，NTCC-LMG 18002 和 NTCC-CECT 4664。
