“…They are also common in the guts of wood-eating termites, where they break down cellulose (Femi-Ola and Oyebamiji 2019). Most intriguingly, Ehsani et al (2019) showed that Achromobacter became highly abundant in enriched hydrogen-oxidizing microbiomes, where they converted mineral nitrogen and carbon dioxide directly into microbial biomass. This autotrophic production is a promising source of protein production since hydrogen-oxidizing microbes have elevated levels of high-quality protein with desirable amino acid profiles (Ehsani et al 2019).…”

Characterizing patterns in the microbial communities that dwell within key species is critical to understanding the role of microbes in shaping fundamental aspects of marine ecosystems. Sea urchins are key grazers in coastal seas, where they can survive a variety of conditions and diets, enhancing their ecological impact on kelp forests. Here we provide the first evidence that the two dominant sea urchin species in southern California have distinct gut microbiomes that vary with habitat. The taxonomic composition of the urchin microbiomes suggests that they may facilitate digestion of food and be a source of nutrition themselves. More work is needed to understand the extent to which their microbiome is the key to sea urchins' ecological success.

“…The combined system was demonstrated to be more efficient than direct immersion of the electrodes in the fermenter [262]. Still in most cases water is typically split in electrochemical cells and the off-gas hydrogen is fed to the fermenters where, it is mixed with CO 2 and the oxygen provided by the anode and the hydrogenotrophs grow in suspension [263]. This indicates that separate water electrolysis in an electrolyser, which can efficiently split the water to H 2 and O 2 and subsequent utilization of the H 2 generated in a separate reactor, is to be preferred.…”

“…HOB can fix CO 2 and utilize H 2 , a promising carrier of renewable energy, to grow biomass rich in protein (60-70% of dry biomass) containing most essential amino acids required by aquaculture, livestock, and human beings [1][2][3]7]. While 70% of the nitrogen fertilizers used in agriculture are lost to the environment, reactive nitrogen discharge from HOB production can be minimized using strategies such as up to 100% upgrade of reactive nitrogen [2,[8][9][10]. Besides, reactor-based HOB production can use marginal land rather than compete with agriculture for limited fertile land [8].…”

“…-based H 2 -oxidizing community from a reactor operated at 28 • C as an inoculum, a gas mixture of 2% O 2 , 10% H 2 , 10% CO 2 , and 78% N 2 (initial composition) and a nitrogen-free mineral medium were used to obtain the enrichment that could consume gas to grow at 28 • C [3,10,29]. The enrichment was used for an isolation campaign after 110 days of batch-mode operation in gastight serum bottles [21].…”
