The results of the selection new plant growth-promoting bacteria resistant to herbicides different chemical structure are presented. Two methods were used for screening: sowing on microbiological media from freshly sampled soil and obtaining enrichment cultures samples exposed a month at temperature 28 °C. Inoculation was carried out selective nutrient containing Octapon extra (2,5 g/l), Florax Dicamba (1 Nanomet Spetsnaz g/l) or Chistalan g/l). These commonly control weeds in wheat crops. isolated microorganisms belong genus Pseudomonas, fix nitrogen, mobilize phosphates, synthesize phytohormones antimicrobial compounds. They also can mitigate pesticide stress An anti-stress biological product them has been developed tentatively named "AGROBIOLOG". For its production, optimal composition medium conditions industrial submerged cultivation reactors various volumes determined. In laboratory fermenter FA10 with volume 10 liters after 72 hours °C, stirrer speed 200 rpm, aeration 0.5 air per 1 min medium, amount viable cells billion CFU/ml culture liquid. Cultivation 1000 under same allowed achieve titer 6.0

More food is needed to meet the demand of global population, which growing continuously. Chemical fertilizers have been used for a long time increase crop yields, and may negative effect on human health agricultural environment. In order make ongoing development more sustainable, use chemical will likely be reduced. Microbial fertilizer kind nutrient-rich environmentally friendly biological made from plant growth-promoting bacteria (PGPR). can regulate soil nutrient dynamics promote cycling by improving microbial community changes. This process helps restore ecosystem, in turn promotes uptake, regulates growth, enhances resistance biotic abiotic stresses. paper reviews classification their function regulating nitrogen fixation, phosphorus, potassium solubilization, production phytohormones. We also summarize role PGPR helping crops against Finally, we discuss mechanism applying remediation. review us understand research progress provides new perspectives regarding future agent sustainable agriculture.

Metsulfuron-methyl, a widely used herbicide, could cause damage to the sensitive plants in crop-rotation systems at extremely low levels soil. The potential of plant growth-promoting bacteria (PGPB) for enhancing resistance against herbicide stress has been discovered recently. Therefore, it is poorly understood how physiological processes occur plants, while PGPB reduce phytotoxicity herbicides agricultural crops. In greenhouse studies, effect strains Pseudomonas protegens DA1.2 and chlororaphis 4CH on oxidative damage, acetolactate synthase (ALS), enzymatic non-enzymatic antioxidants canola (Brassica napus L.), wheat (Triticum aestivum L.) were investigated under two (0.05 0.25 mg∙kg-1) metsulfuron-methyl using spectrophotometric assays. inoculation herbicide-exposed with significantly increased shoots fresh weight (24-28%), amount glutathione GSH (60-73%), flavonoids (5-14%), as well activity ascorbate peroxidase (129-140%), superoxide dismutase SOD (35-49%), ALS (50-57%). Bacterial treatment stimulated (37-94%), (65-73%), reductase (19-20%), accumulation (61-261%), (17-22%), (27-33%) canola. Simultaneous prevented lipid peroxidation induced by plants. Based findings, possible that protective role bacterial metsulfuron-metil linked antioxidant system activation.

Plant growth-promoting rhizobacteria (PGPR) can be utilized to enhance plant growth and production. The use of efficient PGPR is one the effective ways improve Triticum aestivum (wheat) nutrition. exploration native rhizobacterial strains as biofertilizers with suitable carriers in immobilized form an alternative way prevent soil ecosystem pollution. In order evaluate potential multiple attributes, numerous experiments were conducted on isolated strains. impact auxin-producing (APRS) various parameters wheat was examined through laboratory field experiments. This study aimed investigate (isolated from crop types) encourage by immobilization alginate beads. PGPR, obtained different rhizospheric soils, identified based their colony morphology biochemical characteristics. addition, they evaluated for ability produce indole-3-acetic acid (IAA), hydrogen cyanide (HCN), ammonia (NH3), siderophores. 16S rRNA-based identification revealed that showed homology genera, including Bacillus, Brevundimonas, Exiguobacterium spp. Selected (PGP) attributes hydrolytic enzyme-producing abilities. Most had multifaceted attributes. Growth potential, assessed under natural environments, confirmed efficacy bacterial beads biofertilizers. Encapsulation a 70–80% improvement seed germination 60–70% enhancement root shoot length than control. results selected strain used Screening application encapsulation better option promote production yield wheat.

The Moroccan endemic Vachellia gummifera grows wild under extreme desert conditions. This plant could be used as an alternative fodder for goats, and camels, in order to protect the Argan forests against overgrazing Central Southwestern semiarid areas. With aim improve V. population's density areas, we proposed its inoculation with performing growth-promoting bacteria. Hence, 500 bacteria were isolated from rhizosphere. From these, 291 isolates retained (PGP) activities assessment. A total of 44 showed best phosphates solubilization potential, well siderophore auxin production. combination REP-PCR (repetitive extragenic palindromic-polymerase chain reaction) fingerprinting, PGP activities, phenotypic properties, allowed selection three strains experiments. selected strains' 16S rRNA sequencing that they are members Enterobacter Pseudomonas genera. had diverse effects on growth parameters. All single combined inoculations improved shoot weight by more than 200%, root length up 139%, while some combinations further protein chlorophyll content, thereby improving plant's forage value. constitute effective inoculum use arid zones southern Morocco.

The ability of some rhizosphere bacteria to mitigate herbicidal stress in cultivated plants may be useful agriculture and bioremediation. There is poor understanding how directly or through herbicide degradation affect the biochemical processes exposed sulfonylurea herbicides. In this study, treatment with a combination metsulfuron-methyl (MSM) (Pseudomonas protegens DA1.2 P. chlororaphis 4CH) wheat (Triticum aestivum L.) canola (Brassica napus was carried out. Activity glutathione-S-transferase (GST), an important enzyme for detoxification, acetolactate synthase (ALS), target MSM plants, measured by spectrophotometric assays. residues were analyzed using HPLC-MS. Then, 24 h after bacterial treatment, GST activity increased 75–91% 38–94% canola. On 30th day, decrease soil associated 54.6–79.7%. An increase acceleration accompanied inhibition ALS which indicated mitigation toxic effect. results obtained are evidence that rhizospheric can have beneficial effects on due abilities detoxification enzymes degrade soil.
