Pesticide residue contamination in raw materials influences the quality of fermented products. This study investigated effects bifenthrin (1, 3, 5, and 30 mg/L) tea broth on composition metabolite profiles kombucha tea. Bifenthrin at mg/L (B30) showed an adverse effect composition, with reduced 0.63–1 log CFU/mL each microbial group (acetic acid bacteria, lactic yeast), while lower concentrations gave decreased 0.30–0.84 culture. The presence altered metabolites instigated intervening metabolisms, such as arginine biosynthesis pyrimidine metabolism, which resulted production amino acids, derivatives, organic other beneficial compounds. B30 addition also flavonoid content antioxidant activity by 16% (0.143–0.223 mg quercetin/mL) 5% (0.239–0.278 Trolox/mL), respectively.

Low Caffeine Concentrations Induce Callus and Direct Organogenesis in Tissue Cultures of Ornithogalum dubium

Plants, Journal Year: 2025, Volume and Issue: 14(7), P. 1127 - 1127

Published: April 5, 2025

Caffeine is a nitrogenous base that naturally occurs in coffee (Cafea arabica), tea (Thea sinensis), and cocoa (Theobroma cacao). Chemically, caffeine 1,3,5-trimethylxanthine, purine analogue. Due to significant human consumption, effects have been widely studied. Being natural xanthine derivative, the key degradative enzyme oxidase, converting into 1-methyluric acid. Ecologically, believed act as repellent molecule against insect feeding behavior. Caffeine's chemical similarity purines plant hormones motivated this study, establishing potential for cellular de-differentiation re-differentiation. For this, highly hormone-responsive species, Ornithogalum dubium, was used. As has shown induce endoreplication, new germlines O. dubium attractive. Using tissue culture, range of concentrations were used (0.0125 mg/L 2.0 mg/L) without additional hormones. A difference (p > 0.05) observed intermediate 0.0125, 0.025, 0.05 when compared control (no hormones). The highest rates callus induction obtained at concentration 0.025 mg/mL. Higher phytotoxic (1.0 or greater). To conclude, caffeine-regenerated plants not dissimilar those from canonical

Microbes as Resources to Remove PPCPs and Improve Water Quality

Microbial Biotechnology, Journal Year: 2025, Volume and Issue: 18(1)

Published: Jan. 1, 2025

ABSTRACT The inadequate removal of pharmaceuticals and personal care products (PPCPs) by traditional wastewater treatment plants (WWTPs) poses a significant environmental public health challenge. Residual PPCPs find their way into aquatic ecosystems, leading to bioaccumulation in biota, the dissemination antibiotic resistance genes (ARGs), contamination both water sources vegetables. These persistent pollutants can have negative effects on human health, ranging from development endocrine disruption. To mitigate these risks, there is growing interest exploiting microorganisms enzymes for bioremediation purposes. By harnessing metabolic capabilities microbial communities, be efficiently degraded, transformed, or sequestered systems. Additionally, communities exhibit remarkable adaptability resilience diverse PPCP contaminants, further underscoring potential as sustainable cost‐effective solutions treatment. This review explores promise an approach addressing complex challenges posed contamination, emphasising its safeguard integrity well‐being.

Combined metabolome and transcriptome analyses reveal that growing under Red shade affects secondary metabolite content in Huangjinya green tea

Frontiers in Genetics, Journal Year: 2024, Volume and Issue: 15

Published: April 10, 2024

Shading treatments impact the tea ( Camellia sinensis L.) quality. The sunlight sensitive varieties can be grown under shading nets for better growth and secondary metabolite content. Here, we studied responses of a green variety “Huangjinya” by growing colored (red, yellow, blue, black (75% 95%) rates) to find out most suitable color net. Red was promising treatment as it positively affected weight length 100 one-bud-three leaves reduced degree rate new shoots burn compared control (natural sunlight). We then explored comparative metabolomic changes in response red using UPLC-ESI-MS/MS system. amino acids derivatives, flavonoids, alkaloids were downaccumulated whereas lipids, organic acids, lignans upaccumulated shade samples. caused decreased catechin, epicatechin, dopamine, L-tyramine contents but increased caffeine employed transcriptome sequencing key expressions related genes pathways. Notably, associated with phenylpropanoid flavonoid biosynthesis pathways exhibited complex regulation. These expression suggested potential trend polymerization or condensation simple molecules like catechin pelargonidin into larger glucoside proanthocyanidins. net triggered higher enriched lipid jasmonic acid biosynthesis, suggesting an interplay fatty JA improving performance. findings contribute metabolic Huangjinya which might have implications flavor health benefits. Our data provide foundation further exploration optimization cultivation practices this unique variety.

Effect of Different Levels of Extruded Coffee (Coffea arabica) Pulp Flour on the Productive Performance and Intestinal Morphometry of Cobb 500 Broiler Chickens

Animals, Journal Year: 2024, Volume and Issue: 14(8), P. 1170 - 1170

Published: April 13, 2024

Coffee pulp is a by-product of the coffee industry. Due to conventional management techniques, it represents severe environmental problem due its negative impact on soil (anaerobic fermentation and pH changes), water sources (the infiltration pollutants into streams, acidification sources, modification microorganisms), biodiversity (soil microbiology, fish, crustaceans, other vertebrates). Therefore, essential develop protocols for treatment this waste so that can be used again in productive activities under circular economy approach. This means all from production process reused, generate value benefit producer, and, turn, mitigate impact. The objective study was evaluate replacement 5 levels wheat bran (WB) with extruded flour (ECPF) as an alternative fiber source broiler finisher diets. A total 300 Cobb 500 chickens finishing phase were assessed study, grouped treatments: T1, diet or control (100% WB 0% ECPF), T2 (75% 25% T3 (50% 50% T4 (25% 75% T5 (0% 100% ECPF).
