“…In this regard, several members of the phylum Bacillota, including B. subtilis, B. cereus, and P. aryabhattai, are known for their high APA and UA [92][93][94][95]. Moreover, other identified bacterial species from the phylum Pseudomonadota, including B. bullata as well as several Brucella and Pseudomonas species, can produce diverse types of phosphatases [93,[96][97][98][99][100] and ureases [101,102].…”

Biochar (Bc) and liquid vermicompost extracts (LVEs) are increasingly being used as biofertilizers in agriculture to promote soil-microbe-crop interactions. However, although both these products can potentially act synergistically due to their complementary characteristics, their co-application in different soils has not yet been investigated. Therefore, firstly, an LVE-activated biochar (BLVE) was experimentally formulated and the persistence of LVE bacteria over a 60-day storage period was determined. The total number of LVE bacteria increased by 10-fold after 7 days and was stable throughout the entire biochar storage period. In addition, changes in the composition of the bacterial community were observed after 30 days of storage, indicating that taxa less represented in pure LVE may be advantaged upon biochar colonization. Secondly, a microcosm experiment was performed to evaluate whether the biological fertility and enzyme activities of two soils, differing in organic matter content, could be enhanced by the addition of LVE-activated biochar. In this experiment, three different doses of Bc, LVE, and BLVE against the carbon-related biological fertility index (i.e., biological fertility index, BFI) and three enzyme activities over a 21-day incubation period were tested. The BLVE treatment yielded the best results (i.e., BFI +32%, enzyme activities +38%). This indicates that Bc and LVEs can act synergistically to promote soil fertility, quality, and microbial activity. By integrating LVE-activated biochar into their soil management practices, farmers could achieve higher crop yields and healthier products.

“…The effect of LPS from Ochrobactrum quorumnocens strain T1Kr02 on plants was studied as previously described [30]. Potato microplants (Solanum tuberosum L.) cultivar Kondor from the in vitro plant collection of the Department of Plant Breeding, Selection, and Genetics, Faculty of Agronomy, Vavilov University (Saratov, Russia), were used in this work.…”

“…Recently, a number of species isolated from potato roots (Ochrobactrum quorumnocens) [28] and soil (Ochrobactrum chromiisoli) [29] have been described, with Ochrobactrum being the generic name used by the authors. The structure of LPS molecules can serve as the foundation for technologies for the swift identification of pathogenic Brucella and saprophytic Ochrobactrum, owing to the distinct characteristics of antigenic properties and monosaccharide and fatty acid composition, as well as the molecular genetic markers of LPS biosynthesis genes [30].…”

Lipopolysaccharides (LPSs) are major components of the outer membranes of Gram-negative bacteria. In this work, the structure of the O-polysaccharide of Ochrobactrum quorumnocens T1Kr02 was identified by nuclear magnetic resonance (NMR), and the physical–chemical properties and biological activity of LPS were also investigated. The NMR analysis showed that the O-polysaccharide has the following structure: →2)-β-d-Fucf-(1→3)-β-d-Fucp-(1→. The structure of the periplasmic glucan coextracted with LPS was established by NMR spectroscopy and chemical methods: →2)-β-d-Glcp-(1→. Non-stoichiometric modifications were identified in both polysaccharides: 50% of d-fucofuranose residues at position 3 were O-acetylated, and 15% of d-Glcp residues at position 6 were linked with succinate. This is the first report of a polysaccharide containing both d-fucopyranose and d-fucofuranose residues. The fatty acid analysis of the LPS showed the prevalence of 3-hydroxytetradecanoic, hexadecenoic, octadecenoic, lactobacillic, and 27-hydroxyoctacosanoic acids. The dynamic light scattering demonstrated that LPS (in an aqueous solution) formed supramolecular particles with a size of 72.2 nm and a zeta-potential of –21.5 mV. The LPS solution (10 mkg/mL) promoted the growth of potato microplants under in vitro conditions. Thus, LPS of O. quorumnocens T1Kr02 can be recommended as a promoter for plants and as a source of biotechnological production of d-fucose.
