“…There are a few articles devoted to analysis of a limited number of Pseudomonas strains isolated from grain crops of the Russian Federation (Kahala et al, 2012;Yerlikaya et al, 2021;Zhang et al, 2022). According to the published data, the Russian population of Psyr was the variable in the presence/absence and activity of syringomycin.…”

Proteobacteria comprising species of Pseudomonas syringae group cause diseases of many plants around the world. The phytopathogen has a complex taxonomic structure, which is constantly being revised due to the emergence of new molecular and biochemical diagnostic methods. Here for the first time, we describe the genetic and phenotypic diversity of 57 strains of Pseudomonas syringae isolated from affected soybeans, cereals, sunflowers, and other plants in the Russian Federation from 1950 to 2019. Genetic diversity was assessed by Multi Locus Sequence Analysis (MLSA) using fragments of the genes of glyceraldehyde-3-phosphate dehydrogenase (gapdh), the DNA-directed RNA polymerase subunit D (rpoD), gyrase (topoisomerase) B subunit (gyrB), and citrate synthase I (gltA). The synthesis of syringomycin and coronatine by bacteria was assessed by the reaction of susceptible yeast culture, seedlings of barley, tomato, and sunflower, and by presence of toxin genes confirmed by PCR test. The pathogenicity of the strains was confirmed on seedlings of dicotyledonous and monocotyledonous plants of peas, soybean, sunflowers, barley and wheat, as the most affected crops. The sensitivity of bacteria to 10 antibiotics of the main mechanisms of activity and two bactericidal commercial products was tested by standard disc method. The obtained results showed a high genetic homogeneity of the Russian population of P. syringae, which infects various agricultural crops, and an increase in the proportion of antibiotic-resistant strains over the years.

“…Our previous study found that B. subtilis could inhibit spoilage bacteria and prolong the shelf life of chilled large yellow croaker (total number of bacteria, TVB-N and K value were used as indexes) [ 20 ]. Therefore, in this work, we screened six B. subtilis strains isolated from tilapia for in vitro and in vivo adhesion and spoilage tests.…”

Inhibiting the growth of spoilage bacteria, such as Pseudomonas spp., is key to reducing spoilage in fish. The mucus adhesion test in vitro showed that the adhesion ability of Bacillus subtilis was positively correlated with its inhibition ability to Pseudomonas spp. In vivo experiments of tilapia showed that dietary supplementation with B. subtilis could reduce the adhesion and colonization of Pseudomonas spp. in fish intestines and flesh, as well as reduce total volatile basic nitrogen (TVB-N) production. High throughput and metabolomic analysis showed treatment with B. subtilis, especially C6, reduced the growth of Pseudomonas spp., Aeromonas spp., Fusobacterium spp., and Enterobacterium spp., as well as aromatic spoilage compounds associated with these bacteria, such as indole, 2,4-bis(1,1-dimethylethyl)-phenol, 3-methyl-1-butanol, phenol, and 1-octen-3-ol. Our work showed that B. subtilis could improve the flavor of fish by changing the intestinal flora of fish, and it shows great promise as a microecological preservative.

Polyvinyl alcohol-starch (PVA/ST) active films incorporated with lemongrass oil (LMO) or 2-hydroxypropyl-β-cyclodextrin, and LMO (HP-β-CD/LMO) emulsion were developed in the present work. The effects of LMO or HP-β-CD/LMO emulsion on the properties of films, and their application in large yellow croaker preservation were investigated. The average particle size and the encapsulation efficiency of the HP-β-CD/LMO emulsion were 150.07 nm and 81.32%, respectively. The scanning electron microscopy (SEM) results revealed that HP-β-CD improved the compatibility between PVA and starch, and LMO was well embedded in HP-β-CD. The incorporation of LMO or HP-β-CD/LMO enhanced the water vapour barrier property and flexibility of the film while weakening its mechanical strength. The oxygen barrier property of the film was weakened by the incorporation of LMO and strengthened by HP-β-CD/LMO. The film incorporated with HP-β-CD/LMO exhibited a little weaker antioxidant and antibacterial activities than the film containing LMO owing to their release property. The existence of HP-β-CD postponed the release of LMO from the film into food simulant (10% ethanol). The preservation results demonstrated that the film containing LMO or HP-β-CD/LMO efficiently inhibited the growth of microorganisms and lipid oxidation of fish; and delayed the decomposition of protein and freshness reduction of large yellow croaker. Additionally, the film added with HP-β-CD/LMO exhibited the best protection for fish quality. In other words, the film with the proper release property of active agents contributed to the preservation of aquatic products.
