隨著大深度采樣以及原位分析技術(shù)的發(fā)展，越來(lái)越多的證據(jù)表明，在以低溫、高靜水壓為主要特點(diǎn)的深海、深淵環(huán)境中依然有大量微生物在活躍地進(jìn)行物質(zhì)代謝和能量轉(zhuǎn)換。這些嗜壓微生物（piezophiles）和僅能在高壓條件下生長(zhǎng)的嚴(yán)格嗜壓微生物（obligate piezophiles）具有獨(dú)特的遺傳特征、分子組成，并可合成一些耐受高靜水壓的代謝酶類(lèi)，使其能夠在深海、深淵生境中維持正常的生命活動(dòng)。探索深海深淵微生物具有怎樣的遺傳、生理、結(jié)構(gòu)特征，闡明其在極高壓力的極端條件下的生存策略，不僅有助于拓展對(duì)地球生命極限和起源演化等基礎(chǔ)科學(xué)問(wèn)題的認(rèn)知，還將為開(kāi)發(fā)、利用深淵生境中廣闊的新型生物資源奠定堅(jiān)實(shí)基礎(chǔ)。
研究方向：?
1）深海深淵微生物資源挖掘
從不同深海極端環(huán)境（深海冷泉、熱液、深淵等）中進(jìn)行極端微生物菌種（尤其是嗜壓菌和嚴(yán)格嗜壓菌）的分離、鑒定，挖掘新的物種資源，為深海深淵極端微生物的生理功能認(rèn)識(shí)和利用以及生命進(jìn)化研究奠定基礎(chǔ)。?
2）深海深淵微生物的極端環(huán)境適應(yīng)機(jī)制
