Heavy metals, also known as toxic metals, are major environmental pollutants that adversely impact all forms of life, disturbing soil ecology and reducing agricultural productivity. Certain indigenous microbes possess remarkable tolerance to these metals and play a vital role in restoring contaminated soils. In the present study, plant growth-promoting rhizobacteria and fungi were isolated from the rhizosphere and evaluated for their metal tolerance potential. Among the bacterial isolates (Pseudomonas alcaliphila PAS1, Pseudomonas aeruginosa PAS2, Pseudomonas toyotomiensis PTS3, Bacillus subtilis BSS1) expressing resistance to arsenic and lead which observed up to concentrations of 100–1200 ppm on nutrient agar. The fungal isolate Aspergillus japonicus (AJ01) exhibited tolerance up to 200 ppm of Pb and 500 ppm of As. Pot culture experiments were using Arachis hypogaea grown under As and Pb stresses with treatments of PGPR, PGPF, Compost and chemical control. Pseudomonas alcaliphila PAS1 was significantly enhanced plant growth by 100% and Pseudomonas aeruginosa PAS2 by 60% in contaminated soil, indicating strong tolerance and growth-promoting potential. Pseudomonas alcaliphila PAS1 increased chlorophyll content by 92.3% under As stress as compared to the control, while Pseudomonas toyotomiensis PTS3 showed a 70% increased, demonstrating high metal tolerance. In contrast, As and Pb stressed plants showed adverse effects. These findings highlighted the potential of selected PGPR and fungi as eco-friendly alternatives for the remediation and recovery of heavy metal-contaminated soils in Arachis hypogaea cultivation.

Biosurfactant refers to surface-acting substances that can enhance surface-surface interactions by generating micelles that are derived from natural sources including plants, microorganisms, and animals. Biosurfactants are a structurally diverse group of secondary metabolites with lots of potential to serve mankind. The structural and compositional diversity of biosurfactants is unambiguously substrate-dependent. Microbial surfactants are environment-friendly alternatives to synthetic surfactants. Biosurfactants are surface-active agents produced by microorganisms that have higher efficiency and stability, lower toxicity and higher biocompatibility and biodegradability than chemical surfactants. The differences between biosurfactant production can be attributed to the different compositions of the hydrolyzates.

Similar to human beings, fish harbor microorganisms in their gastrointestinal tract (GIT). Fishes are diverse groups of gut microbiota, including protists, fungi, yeasts, viruses, bacteria, and archaea. In addition to serving as a barrier against infections, these microbes that inhabit the gastrointestinal tract of fish play a role in nutrition, physiology, immunity, and life span. All fish have gut microbiota; however, the makeup of these communities varies depending on the fish's life stages, the habitat they live in, their nutrition, the seasons, their trophic level, etc. For both recreational and commercial fisheries, it is crucial to comprehend the bacterial make-up of fish microbiomes. The gut microbiota aids in the development of methods for modifying the gut microbiota of the target fish species to enhance aquaculture quality. These gut microbes are an invaluable, essential source of novel, promising bioactive compounds with significant biological activity. The natural product secondary metabolites from specific strains of Chaetomium spp. may develop to be biomedicine for sustainable protection. This review provides a comprehensive knowledge of the composition of the gut microbiota of fish, their development, changes in the living environment, their modification, and their applications.

The influence of growth regulators and biochemical composition of dwarf mandarin fruits was investigsated. It is shown that heavier fruits (44.8-48.2 g at 41.3 g in the control) are formed during treatment with siliplant, nanoelicitor and zerbra agro due to the formation of a thicker peel (20.1-20.9%), which is associated with the protective mechanism of these drugs which thicker peel is a mechanical protection against pathogens and phytoparasites. Siliplatin treatments provided a higher juice output about 54.5% compared to other growth regulators. Treatments with obstactin and silver agro significantly increased the fructose content in fruits (17.53-16.98 g / kg). The nanoelicitor variant has significantly higher sugar content (107.49 g /kg) due to the content is increased (73.12 g/kg). The use of growth regulators leaded to decrease in ascorbic acid (AA) to 30.61 mg / 100 g, which was shown to be an undesirable factor. The most significantly decreased in ascorbic acid (LSD = 8.27) was noted in variants with obstactin and siliplant treatments. Taking into account, the influence of growth regulators on plant resistance are increased AA synthesis under stress and decreased in ascorbic acid is associated with an improvement in the functional state of tangerine under the influence of non-root treatments. With the introduction of growth regulators, there was significantly increased in the amount of polyphenols (up to 9.33 mg /g at 7.72 mg /g in the control), especially on variants with treatments with obstactin (7.53 mg /g), siliplant (7.39 mg /g) and zerebra agro (7.33 mg/g). Treatments with growth regulators leaded to a significant increase in the Rutin in mandarin fruits (from 7.39 to 7.58 mg /g). The highest values of vitamin P were noted in the variant with obstactin and nanoelicitor treatment (7.53-7.58 mg/g at 6.68 mg/g). Nanoelicitor treatments accelerated fruit ripening, which represented to consumer value and economic benefits of growing crops for the resort town/area.
