“…While providing phosphorus to plants, they enhance the solubility of phosphorus, increase the content of inorganic phosphorus in the soil, reduce phosphorus fixation, and effectively increase phosphorus content. They include Bacillus, Pseudomonas [134], Rhizobium [135], and Burkholderia [136]. Acids are effective in dissolving insoluble chelates in the soil [137,138], and these bacteria increase phosphorus effectiveness and drive phosphorus cycling through their own secretions and metabolites [139], as shown in Figure 2.…”

Phosphorus (P) stands as a pivotal macroelement in relation to the growth of plants. It plays a significant role in physiological processes, as components of biofilms and nucleotides, and in metabolic activities within plants. The deprivation of phosphorus detrimentally impacts the growth and developmental of plants. However, the rhizosphere’s beneficial fungi and bacteria augment the efficacy of phosphorus uptake, participate in the molecular regulation of phosphorus, stimulate physiological alterations in plants, and facilitate signal transmission. In order to give readers a better understanding of the effects and positive roles of soil beneficial fungi and bacteria in regulating plant phosphorus acquisition and transport, this present review introduces the role and influence of rhizosphere microorganisms (fungi and bacteria) in assisting plant phosphorus absorption, and summarizes the key phosphorus transporters found in their interaction with plants. Using mixed microbial populations as composite microbial fertilizers has a positive effect on plants under phosphorus-deficiency conditions. It will be conducive to a better understanding of the mutualistic relationship between fungi, bacteria, and plants to provide a way to reduce the application of phosphorus fertilizers efficiently, and to provide a research background for the development of microbiological fertilizers.

“…Noni fruit extract's antifungal activity has been indicated against several fungal strains, including Candida spp. and Aspergillus spp., suggesting its potential utility against various fungal infections [10,20,21]. Fungal oral cavity infections, often associated with compromised immunity, can lead to conditions such as oral candidiasis, denture stomatitis, and angular cheilitis [22,23].…”

The escalating threat of antibiotic-resistant microorganisms necessitates innovative therapeutic approaches. This study explores the pharmaceutical potential of Noni Fruit Extract (NFE), derived from Morinda citrifolia, as a promising solution against antibiotic-resistant strains and oral pathogens. NFE exhibited robust antibacterial activity, rivaling conventional antibiotics. The investigation encompassed a spectrum of microorganisms, including Gram-positive (Staphylococcus aureus, Bacillus subtilis, Enterococcus faecalis), Gram-negative (Pseudomonas aeruginosa, Proteus vulgaris, Escherichia coli, Salmonella typhimurium, Klebsiella pneumoniae), antibiotic-resistant strains (Vancomycin-Resistant Enterococci (VRE), Methicillin-Resistant Staphylococcus aureus (MRSA)), a fungal pathogen (Candida albicans), and oral pathogens (Streptococcus mutans, Streptococcus mitis). The disk diffusion method determined NFE's inhibition zone diameters against these pathogens. NFE displayed potent antibacterial activity against both Gram-negative and Gram-positive microorganisms. At 5mg/mL, NFE produced a 10 mm inhibition zone against Pseudomonas aeruginosa, reaching 19.3 mm at 100mg/mL. Proteus vulgaris exhibited zones of 10.3, 12.7, 27.3, 33.7, and 44.7 mm at NFE concentrations from 5 to 100 mg/mL. Escherichia coli displayed the largest inhibition zone of 61.7 mm at 100 mg/mL NFE. Similar trends were observed for Salmonella typhimurium and Klebsiella pneumoniae. NFE also demonstrated strong antifungal activity against Candida albicans. Against antibiotic-resistant strains, NFE significantly affected VRE at 100mg/mL, yielding a 42.3 mm zone. MRSA displayed an 8.3 mm zone at 5 mg/mL NFE and 51.3 mm below 100 mg/mL, underscoring NFE's efficacy against antibiotic-resistant strains. NFE exhibited robust antibacterial activity against oral pathogens, with notable inhibition zones at higher concentrations on Streptococcus mutans and Streptococcus mitis. Following EN 1276:2019 methodology, time-dependent antibacterial efficacy assessment revealed significant log reductions in microbial load, indicating NFE's potent antibacterial effect at various concentrations and contact times. In conclusion, NFE displayed potent antibacterial and antifungal activities against various microorganisms, including antibiotic-resistant strains and oral pathogens. These findings suggest NFE's promise as an alternative therapeutic agent in combatting antimicrobial resistance.
