Dissimilatory sulfate reduction, using sulfate as an electron acceptor and organic compounds or hydrogen as electron donors, plays a significant role in the global sulfur and carbon cycles.(...)

Abstract: Iron is an essential element in life. It is used in a variety of different processes in the energetic metabolism of different organisms. Among these bioenergetic processes is photoferrotrophy, characterized by the utilization of Fe(II) as the sole electron source for photosynthesis. The metabolic activity of photoferrotrophs is proposed to have had a relevant role in the formation of ancient geological structures consisting of Fe(III) minerals, such as the Banded Iron Formations.(...)

Authors: Resende, Ana Paula Martins Farinha Abstract: Cereals are the most important food source, and rice (Oryza sativa L.) alois the staple crop for more than half of the world’s population. Environmenstresses limit plant growth and productivity, and in the case of rice, drouhas become the most serious constraint to yield potential in all agro-climazones. The challenge for the next generations is thus to achievesustainable rice production with less arable land, reduced inputs agrochemicals (fertilizers and pesticides) and above all, with limited wasupply, given the increasing scarcity of water resources at global level(...)
