In what ways are archaea similar to bacteria
WebBacteria and archaea are microbes consisting of only a single cell. They are similar in many aspects, including sizes, shapes, reproduction, and habitats. Both are much simpler … WebThe production of pigments by halophilic archaea has been analysed during the last half a century. The main reasons that sustains this research are: (i) many haloarchaeal species possess high carotenoids production availability; (ii) downstream processes related to carotenoid isolation from haloarchaea is relatively quick, easy and cheap; (iii) …
