Arbuscular mycorrhizal fungi (AMF) form symbiotic relationships with the roots of nearly all land-dwelling plants, increasing growth and productivity, especially during abiotic stress. AMF improves plant development by improving nutrient acquisition, such as phosphorus, water, mineral uptake. tolerance resilience to stressors drought, salt, heavy metal toxicity. These benefits come from arbuscular interface, which lets fungal partners exchange nutrients, signalling molecules, protective chemical compounds. Plants' antioxidant defence systems, osmotic adjustment, hormone regulation are also affected infestation. responses promote performance, photosynthetic efficiency, biomass production in stress conditions. As a result its positive effects on soil structure, cycling, carbon sequestration, contributes maintenance resilient ecosystems. The AMFs ecological stability species- environment-specific.

Comparative antioxidant activity and phytochemical content of five extracts of Pleurotus ostreatus (oyster mushroom)

Scientific Reports, Год журнала: 2024, Номер 14(1)

Опубликована: Фев. 15, 2024

Abstract Reactive oxygen species reacts with numerous molecules in the body system causing oxidative damage, which requires antioxidants to ameliorate. Pleurotus ostreatus , a highly nutritious edible mushroom, has been reported be rich bioactive compounds. This study evaluated comparative antioxidant activity and phytochemical contents of five extracts P. : aqueous (AE), chloroform (CE), ethanol (EE), methanol (ME) n-hexane (HE). The composition were determined using standard in-vitro assay methods. Results showed that contained alkaloids, tannins, saponins, flavonoids, terpenoids, phenolics, cardiac glycosides, carbohydrates, anthrocyanins, betacyanins varied amounts. CE had highest flavonoid content (104.83 ± 29.46 mg/100 g); AE gave phenol 24.14 0.02 g; tannin was EE (25.12 0.06 HE amounts alkaloids (187.60 0.28 g) saponins (0.16 0.00 g). Antioxidant analyses revealed best hydroxyl radical 250% at 100 µg/ml ferric cyanide reducing power 8495 µg/ml; ME maximum DPPH (87.67%) hydrogen peroxide scavenging (65.58%) 500 nitric oxide inhibition 65.81% ascorbate peroxidase 1.60 (iU/l). total capacity (5.27 GAE µg/ml) ferrous iron chelating (99.23% while guaiacol 0.20(iU/l). characteristics (IC 50 ) followed order: > HE. Overall, extraction solvent for . high phenolic compounds, makes it source potential candidate development new therapies variety stress-related disorders.

Light regulation of secondary metabolism in fungi

Journal of Biological Engineering, Год журнала: 2023, Номер 17(1)

Опубликована: Авг. 31, 2023

Abstract Fungi have evolved unique metabolic regulation mechanisms for adapting to the changing environments. One of key features fungal adaptation is production secondary metabolites (SMs), which are essential survival and beneficial organism. Many these SMs produced in response environmental cues, such as light. In all species studied, Velvet complex transcription factor VeA a central player light regulatory network. addition growth development, intensity wavelength affects formation broad range metabolites. Recent studies, mainly on genus Aspergillus , revealed that dimer VeA-VelB LaeA does not only regulate gene expression light, but can also be involved regulating SMs. Furthermore, complexes wide effect different types this review, we discussed role metabolism. addition, reviewed photoreceptors, factors, signaling pathways light-dependent The effects factors metabolites, well potential applications pharmaceuticals other products were discussed. Finally, provided an overview current research field suggested areas future research.

Food Research International, Год журнала: 2024, Номер 182, С. 114146 - 114146

Опубликована: Фев. 18, 2024

This study evaluated the nutritional quality of different microbial biomass samples by assessing their protein digestibility and carbohydrate fermentability in colon using vitro methods. Four were produced: one hydrogen-oxidizing bacterial strain (Nocardioides nitrophenolicus KGS-27), two strains filamentous fungi (Rhizopus oligosporus Paecilomyces variotii), yeast (Rhodotorula babjevae). The microorganisms grown bioreactors, harvested dried before analysis. commercial fungal product Quorn was used as a reference. analysed INFOGEST model, followed quantification N-terminal amine groups. An faecal fermentation experiment also performed to evaluate degradation carbohydrates formation short-chain fatty acids (SCFA). had higher hydrolysis (60-75%) than sample (12%) (45%), while highest (85%). Heat-treatment significantly reduced its digestibility. Total dietary fibre (DF) content 31 – 43%(DW), mostly insoluble, whereas contained mainly soluble DF (total DF: 25.7%, which 23.5% 2.2% insoluble). After 24 h colonic fermentation, SCFA production from Paecilomyces, Rhodotorula similar that wheat bran, 17% 32% less produced Rhizopus strain, respectively. Further studies are needed clarify reasons for observed differences fermentability, especially regarding cell wall structures role post-processing.
