In this paper Suyash Gupta and her colleagues found the key microbes that convert toxic sulfide to sulfur in a haloalkaliphilic biodesulfurization systems. Furthermore, they also studied at what conditions these microbial workhorses prefer to grow and why.
It’s a major telling change to see the active members of the microbial community over previous overall composition. The former could help in better understanding of inner workings of a biodesulfurization system. They achieved this anew by complimenting 16sRNA analyses with both DNA and RNA comparisons. Strains of Alkalilimnicola ehrlichii and Thioalkalivibrio sulfidiphilus were confirmed as the most active key bacteria. Moreover, the composition of these microbial communities is dependent on residence time, sulfide concentration, and more minor influences.
