Mayanne Karla da Silva et al.
We studied the culturable fungal community recovered from deep marine sediments in the maritime Antarctic, and assessed their capabilities to produce exoenzymes, emulsifiers and metabolites with phytotoxic activity. Sixty-eight Ascomycota f...
Astrobiological implications of the organic and inorganic cyanide utilization by a novel Antarctic hyperthermophilic Pyrococcus strain [0.03%]
一种新型南极嗜热菌株对有机和无机氰化物的利用及其天体生物学意义
Patricio A Uribe-Redlich,Maximiliano J Amenabar,Geraldine V Dennett et al.
Patricio A Uribe-Redlich et al.
Organic and inorganic cyanides are widely distributed in nature, yet not much is known about the ability of microorganisms to use these compounds as a source of nitrogen and/or carbon at high temperatures (>80 °C). Here we studied the capa...
A novel alkane monooxygenase evolved from a broken piece of ribonucleotide reductase in Geobacillus kaustophilus HTA426 isolated from Mariana Trench [0.03%]
从马里亚纳海沟中分离的Geobacillus kaustophilus HTA426中进化出的一段断裂的核糖核苷酸还原酶片段衍生的一种新型烷基单加氧酶

Tanasap Nithimethachoke
We have accidentally found that a thermophilic Geobacillus kaustophilus HTA426 is capable of degrading alkanes although it has no alkane oxygenating enzyme genes. Our experimental results revealed that a putative ribonucleotide reductase sm...
