“…ANT_WA51 were obtained from a collection of bacterial cultures that were previously isolated from the soil samples taken in 2012 from King George Island (Antarctica; GPS coordinates: 62 09.6010 S, 58 28.4640 W) ( Romaniuk et al, 2018 ). Alfalfa ( Medicago sativa L., TANGO type) was selected as a plant representing the Leguminosae family (legumes) of high agricultural importance ( Kulkarni et al, 2018 ) and bioremediation potential ( Debiec-Andrzejewska et al, 2020 ).…”

Iron is the fourth most abundant element on earth. However, its low bioavailability is a key plant-growth limiting factor. Bacteria play an important role in plant growth promotion since they produce specific secondary metabolites that may increase macro- and micronutrient accessibility in soil. Therefore, bacterial-derived iron chelators, as well as surface-active compounds, are recognised as essential to plant welfare. In this study, three cold-active Antarctic bacterial strains, i.e. Pseudomonas sp. ANT_H12B, Psychrobacter sp. ANT_H59 and Bacillus sp. ANT_WA51, were analysed. The physiological and genomic characterisation of these strains revealed their potential for plant growth promotion, reflected in the production of various biomolecules, including biosurfactants (that may lower the medium surface tension of even up to 53%) and siderophores (including ANT_H12B-produced mixed-type siderophore that demonstrated the highest production, reaching the concentration of up to 1.065 mM), increasing the availability of nutrients in the environment and neutralising fungal pathogens. Tested bacteria demonstrated an ability to promote the growth of a model plant, alfalfa, increasing shoots’ length and fresh biomass even up to 26 and 46% respectively; while their metabolites increased the bioavailability of iron in soil up to 40%. It was also revealed that the introduced strains did not disrupt physicochemical conditions and indigenous soil microbial composition, which suggests that they are promising amendments preserving the natural biodiversity of soil and increasing its fertility.

“…Potted garden soil, the properties of which were examined and described in the previous work ( Debiec-Andrzejewska et al, 2020 ), was used for the experiments. The initial pH and redox potential were 6.37 (+/− 0.6) and 32.7 (+/− 0.58), respectively.…”

“…For example, the presence of Ensifer sp. M14 strain in soil contributed to the increase of both growth and arsenic-uptake efficiency in alfalfa (Medicago sativa L., TANGO type) (Debiec-Andrzejewska et al, 2020). Compared to non-bioaugmented soil, the biomass of plants increased by about 60%, while the arsenic accumulation by alfalfa increased more than twice after 40 days (Debiec-Andrzejewska et al, 2020).…”

Arsenic (As) is a metalloid that occurs widely in the environment. The biological oxidation of arsenite [As(III)] to arsenate [As(V)] is considered a strategy to reduce arsenic toxicity and provide energy. In recent years, research interests in microbial As(III) oxidation have been growing, and related new achievements have been revealed. This review focuses on the highlighting of the novel regulatory mechanisms of bacterial As(III) oxidation, the physiological relevance of different arsenic sensing systems and functional relationship between microbial As(III) oxidation and those of chemotaxis, phosphate uptake, carbon metabolism and energy generation. The implication to environmental bioremediation applications of As(III)-oxidizing strains, the knowledge gaps and perspectives are also discussed.

“…Arsenic-oxidizing bacteria contain the arsenite oxidase gene (aioA), which can mediate arsenic oxidation, and their activities, such as in Ensifer sp. and Acinetobacter sp., lead to reduced toxicity of arsenic in soil and may help to stimulate the growth/activity of indigenous microorganisms in soil and promote the remediation of arsenic-contaminated soil by hyperaccumulator plants ( Wang et al, 2012 ; Debiec-Andrzejewska et al, 2020 ). The genetically engineered bacteria Pseudomonas putida KT2440, Bacillus subtilis , and Westerdykella aurantiaca contain the As(III) S -adenosylmethionine methyltransferase gene (arsM) in their cells, which can methylate arsenic to methyl arsenate [MAs(V)], dimethyl arsenate [DMAs(V)] and trimethyl arsenic oxide [TMAs(V)O] to promote the production of volatile arsenic compounds, thereby reducing the inorganic arsenic content in soil ( Chen et al, 2014 ; Verma et al, 2016 ).…”

Iron-oxidizing bacteria (FeOB) could oxidize Fe(II) and mediate biomineralization, which provides the possibility for its potential application in arsenic (As) remediation. In the present study, a strain named Ochrobactrum EEELCW01 isolated previously, was inoculated into paddy soils to investigate the effect of FeOB inoculation on the As migration and transformation in paddy soils. The results showed that inoculation of Ochrobactrum sp. increased the proportion of As in iron-aluminum oxide binding fraction, which reduced the As bioavailability in paddy soils and effectively reduced the As accumulation in rice tissues. Moreover, the inoculation of iron oxidizing bacteria increased the abundance of KD4-96, Pedosphaeraceae and other bacteria in the soils, which could reduce the As toxicity in the soil through biotransformation. The abundance of metabolites such as carnosine, MG (0:0/14:0/0:0) and pantetheine 4’-phosphate increased in rhizosphere soils inoculated with FeOB, which indicated that the defense ability of soil-microorganism-plant system against peroxidation caused by As was enhanced. This study proved that FeOB have the potential application in remediation of As pollution in paddy soil, FeOB promotes the formation of iron oxide in paddy soil, and then adsorbed and coprecipitated with arsenic. On the other hand, the inoculation of Ochrobactrum sp. change soil microbial community structure and soil metabolism, increase the abundance of FeOB in soil, promote the biotransformation process of As in soil, and enhance the resistance of soil to peroxide pollution (As pollution).
