In this study, acetic acid bacteria (AAB) are isolated from fruit waste and cow dung on the basis of acetic acid production potential. The AAB were identified based on halo-zones produced in the Glucose-Yeast extract-Calcium carbonate (GYC media) agar plates. In the current study, maximum acetic acid yield is reported to be 4.88 g/100 ml from the bacterial strain isolated from apple waste. With the help of RSM (Response surface methodology) tool, glucose and ethanol concentration and incubation period, as independent variable showed the significant effect of glucose concentration and incubation period and their interaction on the AA yield. A hypothetical model of artificial neural network (ANN) was also used to compare the predicted value from RSM. Acetic acid production through the biological route can be the sustainable and clean approach to utilizing food waste in circular economy approach.

Objectives: Recent evidence suggests that the gut may be a primary site of metformin action. However, studies on the effects of metformin on gut microbiota remain limited, and its impact on gut microbial metabolites such as short-/medium-chain fatty acids is unclear. This study aims to investigate the effects of metformin on gut microbiota, short-/medium-chain fatty acids, and associated metabolic benefits in high-fat diet rats.

This review discusses the research progress of regulating tree dwarfing in fruit tree rootstocks, including its definition, manifestation, mechanism and application of different rootstocks. Studies indicate that dwarfing rootstocks reduce vegetative growth while promoting reproductive growth. Compared with vigorous rootstocks, the contents of indole-3-acetic acid, cytokinin, and gibberellin in leaves is lower, while the content of abscisic acid is higher.

Fungal diseases in agricultural crops cause economic losses, with chemical control being the conventional method to manage them. However, this approach negatively impacts both the environment and human health. This study focused on endophytic fungi isolated from the roots of Ceratozamia mirandae in the Mexican locality of Juan Sabines (Villa Corzo, Chiapas).

Managing Euschistus heros is increasingly challenging due to insecticide resistance, limited available molecules, and environmental and health concerns. Here, we synthesized and evaluated mucochloric acid derivatives as alternative tools for controlling this pest. We assessed the selectivity of these molecules toward the pollinators bees Apis mellifera and Partamona helleri and conducted in silico predictions for the interactions of these molecules with receptors for γ-aminobutyric acid (GABARs) and nicotinic acetylcholine receptors (nAChRs), and the enzyme acetylcholinesterases (AChE) of E.

Background: Previous studies involving cleanup via conventional solid-phase extraction (SPE) materials to overcome matrix effects for the polar organophosphonate and -phosphinate pesticides glyphosate, glufosinate, ethephon, fosetyl, and their various metabolites often showed limitations due to the existence of various matrix compounds in plant commodities with similar polarity. To overcome existing drawbacks, we utilized the unique selectivity provided by metal oxides as SPE materials. These were exploited in a novel automated online SPE-LC-MS/MS method which allowed analyte-specific trapping in the presence of excessive amounts of matrix compounds as typically contained in extracts of the Quick Polar Pesticides (QuPPe) method.
