“…Cyanobacteria has already been mentioned above. Chelatococcus is an aerobic denitrifying bacteria genus and attracted a lot of attention for its denitrification rate, comparable, if not higher, to that of anaerobic denitrification in biotrickling filters [73]. Moreover, Chelatococcus can reduce atmospheric dinitrogen when living in symbiosis with leguminous plants [74].…”

It is essential to investigate to which extent and how specifically soil–plant–microbe interactions can be conditioned by different agricultural practices. Legumes such as Vicia faba is one of the essential functional group in intercropping and crop rotations due to its higher N fixing capacity. Hence, it is important to study the living microbial community of this legume. Further, it is also expected that fluctuations in soil microbial diversity and composition could be complemented by plant phenological stages and different fertilizer amendments. Thus, we investigated bacterial community composition in soil treated with phosphate-based inorganic and organic fertilizers, in the presence of Vicia faba plants at flowering and fruiting time using NGS 16S rRNA gene amplicon sequencing. Further, the evaluation of plant biomass parameters under different fertilizer treatments was also carried out. The presence of the Vicia faba plant increased the abundance of N fixing bacterial such as Bardyrhizobium, Microvirga (Rhizobiales), Arthrobacter, and Psuedoarthrobacter (Actinomycetales) in soil. Fluctuation in composition and diversity of bacterial community was further supplemented by plant phenological stages. These alterations could be due to changes that occurred in the plant nutrient requirement and varied root exudation patterns at a specific phenological stage. Further, fertilizer treatments also have a profound effect on the diversity and structure of the bacterial community. Organic fertilizers, especially vegetable tanned leather waste (VTLW), have a stronger effect on the composition and diversity of bacterial community compared to inorganic fertilizer (PT—triple superphosphate). Alpha-diversity was significantly decreased by both organic and inorganic amendments, especially a species evenness because each fertilizer tends to stimulate the growth of distinctive microbes that dominated the community of amended soil. Proteobacteria, Actinobacteria, and Cyanobacteria were the most abundant phyla, and Chelatococcus, Cyanobacteria, Sphingomonas, and Microvirga were a most abundant genus that contributed most in co-occurrence pattern, which suggests that these generalists are adapted to a variety of environments. These indicate that plant presence was a key, dominating factor, followed by fertilizers and time, in affecting soil bacterial diversity and composition. Plant recruits system (fertilization and time) -specific taxa due to differences in available nutrients and energy sources among different treatments during different growth stages. Further, fertilizer treatments did not have a stronger effect on plant production as compared to the effect on microbial community, which highlights that organic fertilizers did not tend to increase plant production. Thus, organic and inorganic amendments with matched macronutrients could have a similar impact on crop yields.

“…According to the List of Prokaryotic names with Standing in Nomenclature (LPSN) [2] , this genus comprises six species at the time of writing, namely C. asaccharovorans, C. caeni, C. composti, C. daeguensis, C. reniformis, and C. sambhunathii [1,[3][4][5][6][7] . Most notably, there has been a growing interest in C. daeguensis in the recent years for its capability in utilizing a variety of carbon sources and its capability in performing aerobic denitrification at high temperatures, as well as its capability in biodegrading crude oil, coal and toxic metals [5,[8][9][10][11] . To provide insights into the genomic basis for these mechanisms, we hereby present the draft genome of C. daeguensis M38T9, isolated from Ulu Slim hot spring, Malaysia (3.8986 N 101.4847 E, 110°C, pH 7).…”

“…[4,5] In addition, several alternative processes have been investigated such as using membrane bioreactors (MBRs), rotating drum biofilters, and rotating biological contactors. [6][7][8] There are also combined systems, such as BioDeNOx, which is an integrated physico-chemical and biological process consisting of two discrete reactors, namely a scrubber and a biological reactor. [9][10][11] A chelating agent, Fe(II)(EDTA), is used to improve the transfer of gaseous NO into the scrubbing liquid.…”

Nitrogen monoxide (NO) and nitrogen dioxide referred as NOx are one of the most important air pollutants in the atmosphere. Biological NOx removal technologies have been developing to reach a cost-effective control method for upcoming stringent NOx emission standards. The BioDeNOx system was seen as a promising biological NOx control technology which is composed of two reactors, one for absorbing of NO in an aqueous Fe(II)EDTA2- solution and the other for subsequent reduction to N2 gas in a biological reactor by the denitrification process. In this study, instead of two discrete reactors, only one jet-loop bioreactor (JLBR) was utilized as both absorption and denitrification unit and no chelate-forming chemicals were added. In other words, the advantage of better mass transfer conditions of jet bioreactor was used instead of Fe(II)EDTA2-. The process was named as Jet-BioDeNOx. The JLBR was operated for the removal of NOx from air streams containing 500-3000 ppm NOx and the results showed that the removal efficiency was between 81% and 94%. The air to liquid flow ratio (Q(G)/Q(RAS)) varied in the range of 0.07-0.12. Mathematical modelling of the system demonstrated that the removal efficiency strongly depends on this ratio. The high mass transfer conditions prevailed in the reactor provided a competitive advantage on removing NO gas without any requirement of chelating chemicals.
