The aim was unveil mechanisms that underlie effects different fertilization treatments fertility, enzyme activities, quality. Four were established: sole fertilizer (CF; N:P2O5:K2O is 15:15:15), combined with cake (CF+CC), manure (CF+M), (CF+CC+M). Measurements taken assess nutrient content, growth in some orchards under treatments. results revealed application could increase yield enhance Among these, CF+M+CC treatment demonstrated most favorable outcomes, kernel oil unsaturated fatty acid contents reaching 72.33% 97.54%, respectively. had no significant impacts trace elements such as Mg, Cu, Mn; however, it significantly increased Available Phosphorus (AP), Total Nitrogen (TN), Soil Organic Matter (SOM) S-ACP (soil phosphatase) activities.

Abstract BACKGROUND The widespread use of chemical herbicides and the growing issue weed resistance pose significant challenges in agriculture. To address these problems, there is a pressing need to develop biological based on bacterial metabolites. RESULTS In this study, we investigated impact cell‐free culture filtrate (CFCF) from ZT isolate, bacilliform bacterium obtained diseased wheat seeds, germination seedling growth various plant species, including wild oat, ryegrass, redroot, wheat, chickpea. results revealed that CFCF had detrimental effect fresh dry weight stems roots most studied plants, except chickpeas. was further subjected separation into aqueous organic phases using chloroform, followed by division phase 13 fractions an alumina column. Notably, both (20%) all (ranging 50% 83%) displayed ability reduce root length monocotyledonous weed. Liquid chromatography–mass spectrometry (LC–MS) analysis identified 3 7, which were effective against ryegrass but not contained Cry family proteins, Cry10 Aa, Cry4 Ba, Aa. Additionally, 16s rRNA gene sequencing isolate closely related (98.27%) Bacillus wiedmannii . CONCLUSION Conclusively, metabolites hold promise for weed‐targeted herbicides, providing constructive strategy confront agricultural issues tied resistance. © 2024 Society Chemical Industry.

Assessing the influence of diverse phosphorus sources on bacterial communities and the abundance of phosphorus cycle genes in acidic paddy soils

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

Published: Oct. 10, 2024

The impact of chemical fertilizers on soil microbial communities is well acknowledged. This study assesses the influence various phosphorus sources bacterial composition, abundance, and Phosphorus Cycle Gene Abundance. Three (natural phosphate rock, triple super (TSP), fertilizer NPK) were field tested following two rice cultivation cycles. Soil samples subsequently collected analyzed for groups cycle genes. Results indicated that community composition remained consistent, comprising five main phyla: Firmicutes, Actinobacteria, Proteobacteria, Halobacterota, Chloroflexia, regardless type. NPK significantly reduced relative abundance Chloroflexia by 19% Firmicutes 16.4%, while increasing Actinobacteria Proteobacteria 27.5 58.8%, respectively. TSP increased 27.1% Halobacterota 24.8%, but 8.6%, 12.6%, 0.6%. Phosphate rock application resulted in reductions 27.1%, 22.9%, 6.2%, alongside increases 46.6% 23.8%. Combined TSP, NPK, led to (24-40%) (13-39%), decreases (5.2-22%) (6-12.3%) compared control (T0). While different did not alter genes, they modulate their abundance. affect ppK genes (57-59%) gcd (100 69%), 3-phytase (74 34%), appA (91 63%), phoD (83 67%). 27 15%, respectively, 19%. decreased 42 40%, 34 56%, (49 (10 0%), (27 6%), (72 100%).

The dawn of ethnomicrobiology: an interdisciplinary research field on interactions between humans and microorganisms

Journal of Ethnobiology and Ethnomedicine, Journal Year: 2024, Volume and Issue: 20(1)

Published: Sept. 16, 2024

Ethnobiologists commonly analyze local knowledge systems related to plants, animals, fungi, and ecosystems. However, microbes (bacteria, yeasts, molds, viruses, other organisms), often considered invisible in their interactions with humans, are neglected. Microorganisms were the earliest life forms on Earth, humans have interacted them throughout history. Over time, accumulated ecological about through attributes such as smell, taste, texture that guide management of contexts which microorganisms evolve. These human-microbe are, fact, expressions biocultural diversity. Thus, we propose ethnomicrobiology is a distinct interdisciplinary field within ethnobiology examines practices surrounding interactions, along theoretical contributions an approach can offer.
