Plaque assay is the method traditionally used to isolate and purify lytic viruses, to determine the viral titer and host range. Whereas most bacterioviruses are either temperate or lytic, the majority of known archeoviruses are not lytic (i...
Effect of an overproduction of accessory Gvp proteins on gas vesicle formation in Haloferax volcanii [0.03%]
辅佐Gvp蛋白过量生产对Haloferax volcanii产气泡囊形成的影响

Stella Tavlaridou et al.
Gas vesicle formation in haloarchaea requires the expression of the p-vac region consisting of 14 genes, gvpACNO and gvpDEFGHIJKLM. Expression of gvpFGHIJKLM leads to essential accessory proteins formed in minor amounts. An overexpression o...
The changes in Tps1 activity, trehalose content and expression of TPS1 gene in the psychrotolerant yeast Guehomyces pullulans 17-1 grown at different temperatures [0.03%]
psychrotolerant酵母Guehomyces pullulans 17-1不同培养温度下Tps1活性、trehalose含量及TPS1基因表达量的变化
Fang Zhang,Zhi-Peng Wang,Zhe Chi et al.
Fang Zhang et al.
The psychrotolerant yeast Guehomyces pullulans 17-1 grows the best at 15 °C. When the yeast cells grown at 15 °C for 48 h were transferred to new medium and grown at 10, 15, and 25 °C, respectively, trehalose-6-phosphate synthase (Tps1) ...
Unraveling the function of paralogs of the aldehyde dehydrogenase super family from Sulfolobus solfataricus [0.03%]

Susana Bequer Urbano et al.
The production of triacylglycerols (TAG) or wax esters (WS) seems to be a widespread feature among extremophile bacteria living in high-altitude Andean Lakes (HAAL), Argentina. Twelve out of twenty bacterial strains isolated from HAAL were ...
Deinococcus radiodurans YgjD and YeaZ are involved in the repair of DNA cross-links [0.03%]
