Novel chitosan-zeolite X composite beads prepared by phase-inversion method for CO adsorptive capture.

The urgent need to mitigate carbon emissions from industrial heat production has led to the exploration of novel carbon-based materials for carbon capture. Chitosan, a versatile framework, has been widely utilized for embedding many materials such as grafted graphene oxide, zeolite, and activated carbon to enhance the carbon capture capacity of diverse carbon-based materials. Remarkably, the combination of chitosan and zeolite overcomes the inherent drawbacks of powdery zeolite, resulting in improved stability and efficiency in carbon capture applications.

Identifications of Surfactin-Type Biosurfactants Produced by Species Isolated from Rhizosphere of Vegetables.

Surfactins are cyclic lipopeptides consisting of a β-hydroxy fatty acid of variable chain length and a peptide ring of seven amino acids linked together by a lactone bridge, forming the cyclic structure of the peptide chain. These compounds are produced mainly by species and are well regarded for their antibacterial, antifungal, and antiviral activities. For their surfactin production profiling, several strains isolated from vegetable rhizospheres were identified by their fatty acid methyl ester profiles and were tested against phytopathogen bacteria and fungi.

Optimization of the ultrasonic-assisted extraction process to obtain total phenolic and flavonoid compounds from watermelon ( rind.

This context presents the study of ultrasonic-assisted extraction (UAE) to obtain phenolic and flavonoid compounds from watermelon rind powder (WRP). The antioxidant activity of the extracts was investigated using DPPH and ABTS assays. One-factor experiments were conducted to examine the effect of each factor (solid-to-liquid ratio (SLR), acetone concentration (AC), temperature, and time) on the UAE of WRP.

Optimized Cellulase-Hydrolyzed Deoiled Coconut Cake Powder as Wheat Flour Substitute in Cookies.

Deoiled coconut cake powder (DCCP) was hydrolyzed to reduce the ratio of insoluble/soluble dietary fiber (RIS) by partially converting insoluble dietary fiber to soluble using Celluclast 1.5 L, a commercial cellulase preparation in citrate buffer medium. Firstly, the influence of citrate buffer amount, enzyme concentration, pH, and retention time on the enzymatic hydrolysis efficiency was investigated.

Discrimination between the Two Closely Related Species of the Operational Group Based on Whole-Cell Fatty Acid Profiling.

(1) Background: and are closely related members of the "operational group ", a taxonomical unit above species level within the " species complex". They have similar morphological, physiological, biochemical, phenotypic, and phylogenetic characteristics. Thus, separating these two taxa from each another has proven to be difficult to implement and could not be pushed easily into the line of routine analyses.

Novel (+)-Neoisopulegol-Based -Benzyl Derivatives as Antimicrobial Agents.

Discovery of novel antibacterial agents with new structures, which combat pathogens is an urgent task. In this study, a new library of (+)-neoisopulegol-based -benzyl derivatives of aminodiols and aminotriols was designed and synthesized, and their antimicrobial activity against different bacterial and fungal strains were evaluated. The results showed that this new series of synthetic -benzyl compounds exhibit potent antimicrobial activity.

Rapid prediction of possible inhibitors for SARS-CoV-2 main protease using docking and FPL simulations.

Originating for the first time in Wuhan, China, the outbreak of SARS-CoV-2 has caused a serious global health issue. An effective treatment for SARS-CoV-2 is still unavailable. Therefore, in this study, we have tried to predict a list of potential inhibitors for SARS-CoV-2 main protease (Mpro) using a combination of molecular docking and fast pulling of ligand (FPL) simulations.

Effects of drying conditions in low-temperature microwave-assisted drying on bioactive compounds and antioxidant activity of dehydrated bitter melon ( L.).

Bitter melon ( L.) is a fruit that brings health benefits to consumers because the fruit is rich in bioactive compounds. In this work, a combination of low-temperature convective drying and microwave radiation was used to dehydrate sliced bitter melon.

A novel injectable pH-temperature sensitive hydrogel containing chitosan-insulin electrosprayed nanosphere composite for an insulin delivery system in type I diabetes treatment.

A novel insulin composite delivery system was prepared and characterized. The composite consisted of a pH- and temperature-sensitive hydrogel, which is an oligomer serine-b-poly(lactide)-b-poly(ethylene glycol)-b-poly(lactide)-b-oligomer serine (OS-PLA-PEG-PLA-OS) pentablock copolymer, as matrix and chitosan-insulin electrosprayed nanospheres (CIN) as constituent materials. The properties of the OS-PLA-PEG-PLA-OS pentablock copolymer and the chitosan-insulin nanoparticles were characterized.
