As a substitute for conventional plastic mulch, biodegradable mulch film (BDM) has been popular in agricultural systems recent years. However, studies focusing on the systematic effect of BDM residues soil microbiome and metabolism remain obscure. Thus, mesocosm experiment was established, it aimed to investigate effects concentrations poly(butylene adipate-co-terephthalate) (PBAT) microplastics (MPs) microbial ecology plant (Lactuca sativa) fitness. Metagenomics metabolomics analyses were deployed explore response communities, functional shifts, metabolites under different dosages PBAT MPs (CK, 0.1%, 1%, 5% w/w). The results showed that did not significantly affect morphological traits (shoot length leaf dry weight) plant. Regarding biochemical indicators, highest concentration could increase proline soluble protein contents compared low- medium-dosage treatments with high malonaldehyde (MDA) or sugar contents. Soil physicochemical properties like available phosphorus potassium ammonium N nitrate decreased dose-dependent manner. analysis revealed only had more profound community composition, diversity, function when control (CK). In particular, treatment result development some biomarkers, such as Paraburkholderia Rhizobium, which beneficial functions. Moreover, differentially affected metabolites, abundance bioactives peptides, organic acid derivatives, nepetaside. This work underscores recruit certain microbes bioactive substances resist external high-PBAT stress. might pose little threat ecosystem, its application is health management.

Abstract Background Bacterial siderophores are chelating compounds with the potential of application in agriculture, due to their plant growth-promoting (PGP) properties, however, high production and purification costs limiting factors for wider application. Cost-efficiency could be increased by omitting processes, especially since accompanying metabolites (SAM) often also possess PGP traits. In this study, metabolism versatility Pseudomonas sp. ANT_H12B was used optimization these SAM characterized context properties. Results The metabolic diversity examined through genomic analysis phenotype microarrays. strain found able use numerous C, N, P, S sources, which allowed design novel media suitable efficient form pyoverdine (223.50–512.60 μM). Moreover, depending on culture medium, pH solutions varied from acidic (pH < 5) alkaline > 8). a germination test, were shown have positive effect plants, significant increase percentage observed beetroot, pea, tobacco. further elucidated GC/MS analysis, revealed other potential, such as indolic acetic acids, organic fatty sugars alcohols. These not only improved seed but potentially beneficial fitness soil quality. Conclusions presented an producer exhibit potential. It that downstream processes limit improve agricultural
