“…In Pseudomonas fluorescens WCS374r, pseudobactin PSB 374, salicylic acid, and pseudomonine (PSM) were reported as siderophores (Djavaheri et al, 2012) The results revealed that the P. monteilii strain MN759447 exhibits a unique plant growth promotion property of producing siderophores, which is one of the key mechanisms in the biological control of plant diseases. Therefore, it can also be developed as a broad-spectrum biofungicide for commercial purposes to limit the high mortality rate caused by pathogenic fungi in D. sissoo plantation forests (Shaikh et al, 2016a,b;Hamid et al, 2021;Subba and Mathur, 2022).…”

Siderophore-positive bacteria present in the rhizosphere and in bulk soil assist plants by either inhibiting phytopathogen proliferation or increasing plant growth. The bacterial diversity of the Shisham forest ecosystem in the Tarai region of the Western Himalayas was studied and used for siderophore production, taking into account the large-scale dieback and wilt-induced mortality in Dalbergia sissoo (common name: shisham) plantation forests and the importance of soil microbes in tree health. In addition, Pseudomonas, Burkholderia, and Streptomyces were prominent siderophore-positive bacteria in Shisham forests. Pseudomonas species are known for their remarkable siderophore-producing ability. Bacterial siderophores inhibit pathogen growth by rapidly lowering the number of ferric ions in the rhizosphere. The Pseudomonas monteilii strain MN759447 was isolated from a D. sissoo plantation forest at the Agroforestry Research Centre, Pantnagar, Uttarakhand (28°58′N 79°25′E/28.97°N 79.41°E). It produces a significant number of siderophore units (80.36% in total). A two-stage optimization of growth factors was attempted in the strain MN759447 for better siderophore recovery. In the first-stage single-factor experiment, among the five variables studied, only pH, NH4NO3 concentration, and Fe concentration affected siderophore synthesis. In the second stage, an optimization of pH, NH4NO3 concentration, and Fe concentration for improved growth and enhanced siderophore production was carried out using a Box–Behnken design with response surface methodology. By using LC-MS, two derivatives of pseudomonine, salicylic acid, and kynurenic acid were detected as siderophores in the purified XAD-2 methanol extract of the P. monteilii strain MN759447. In addition to siderophore production, the P. monteilii strain MN759447 also exhibited a broad range of antagonistic activity against Aspergillus calidoustus (65%), Fusarium oxysporum (41.66%), Talaromyces pinophilus (65%), and Talaromyces verruculosus (65.1%) that are linked to sissoo mortality. To our knowledge, this is the first report on siderophore-producing bacteria isolated, identified, and characterized from the D. sissoo Roxb. forest habitat. This strain can also be developed as a commercial product.

“…В последние десятилетия одним из основных путей решения этой задачи во многих странах мира является использование микробиологических средств, обеспечивающих стимуляцию роста и развития растений, защиту от вредных организмов, утилизацию пожнивных остатков и т.п. (Ali et al, 2022;Ebrahimi-Zarandi et al, 2022;Elnahal et al, 2022;O'Callaghan et al, 2022;Ram et al, 2022;Subba, Mathur, 2022). Для снижения пестицидного пресса на агроценозы могут использоваться не только микробиологические средства, но и их смеси с химическими препаратами (Петровский, Каракотов, 2017), причем первые могут способствовать деградации последних, что служит ещё одним преимуществом их совместного применения (Książek-Trela, Szpyrka, 2022).…”

“…обусловлен их способностью синтезировать активные биологические соединения, стимулирующие прорастание семян, рост и развитие растений (Adnan et al, 2019). На черноземных почвах в качестве агента микробиологической защиты перспективен гриб T. harzianum (Свистова, Сенчакова, 2010) с выраженным антибиотическим и фунгицидным действием, эффективно подавляющий фитопатогенные грибы, стимулирующий рост растений и не проявляющий фитотоксических свойств (Asad, 2022;Modrzewska et al, 2022;Salwan et al, 2022;Subba, Mathur, 2022;Tyśkiewicz et al, 2022). А поскольку скорость разложения послеуборочных остатков полевых культур в черноземах Сибири ниже в летний период и выше с сентября по май, с более активным разложением донника, гороха, кукурузы и слабее -яровой пшеницы (Лазарев, Майсямова, 2006), то изучение распада клетчатки в почвах этой зоны в летний период и поиск эффективных биодеструкторов-активаторов весьма актуально.…”

“…Considerable success has been achieved with microbial bioinsecticides such as Bacillus thuringiensis ( Bt ) 1 and microbial biofungicides such as Trichoderma spp 2,3 . It is common for authors to use the term ‘biopesticides’ when they are writing exclusively on bioinsecticides, 1 because they apparently consider bioherbicides a non‐entity.…”

Microbial biopesticides to control plant pathogens and insects in crops have had significant success. However, there have been relatively few successes for microbial bioherbicides in crops, despite considerable numbers of publications and commercial product introductions in this area. Marketed microbial bioherbicide products for use in agriculture have been largely unsuccessful. This article covers the potential advantages of successful microbial bioherbicides, as well as the biological and technical issues that have limited their success. Technologies to overcome the problems that have limited the success of these products are discussed. The many advantages of using killed microbial products (e.g. cell‐free filtrates) over living microbial products as bioherbicides are detailed. A commercialized mycoherbicide that has been selected for in the laboratory for control of the parasitic weed Striga hermonthica is being used with some success in Africa, indicating that non‐transgenic modification of the genetics of bioherbicide microbes for improved efficacy is acceptable to some regulatory authorities. Genetic modifications to improve efficacy and host range, as well as improved application technology to greatly reduce the amount of product needed are two technologies that are likely to expand the use of microbial bioherbicides in the future. © 2023 Society of Chemical Industry.
