Mini Review
Microbiological Genomics and Metabolize energy
Author(s): Dr. Zuhia Mariyam*
Marine sponges host a wide diversity of microorganisms, which have versatile
modes of carbon and energy metabolism. In this study we describe the major
lithoheterotrophic and autotrophic processes in 21 microbial sponge-associated
phyla using novel and existing genomic and transcriptomic datasets. We show
that the main microbial carbon fixation pathways in sponges are the Calvin
Benson Bassham cycle (energized by light in Cyanobacteria, by sulfur compounds
in two orders of Gammaproteobacteria, and by a wide range of compounds
in filamentous Tectomicrobia), the reductive tricarboxylic acid cycle (used by
Nitrospirota), and the 3-hydroxypropionate/4-hydroxybutyrate cycle (active
in Thaumarchaeota). Further, we observed that some sponge symbionts, in
particular Acidobacteria, are capable of assimilating carbon through anaplerotic
processes. The lithoheter.. View More»
