Summary: Modern hospital treatments focus on developing electrochemical biosensors for early disease diagnosis using unconventional human bio-fluids such as sweat and saliva to avoid the use of blood and urine samples. Research has shown that in artificially simulated bio-mimics of sweat and saliva, the electron transfer reaction of the redox couple is diffusion-controlled, but the rate constant values decrease in the presence of a liquid crystalline phase.

Summary: This study investigates the adsorption of H-2 on clay minerals in rocks, revealing that the adsorption capacity depends on the mineral texture rather than its structure. The majority of H-2 is adsorbed in micropores accessible to CO2 and also intercalates in smectitic interlayers. This enhances the gas storage capacity of the rocks.

Summary: Clinical data supporting the efficacy of pharmacological doses of ascorbic acid (AA) in killing cancer cells are still lacking. Inhibition of glycolysis may enhance the anticancer effect of AA by reducing the generation of pyruvate. Experimental results suggest that 2-DG enhances the cytotoxic effect of AA by increasing H2O2 concentration in glycolytic cancer cells, potentially due to lower pyruvate levels as a result of glycolysis inhibition.

Summary: This article proposes a pressure swing adsorption (PSA) process for producing high-purity bio-hydrogen. The process utilizes two columns packed with type 5A zeolite and a four-step configuration for hydrogen production and bed regeneration. An active fault-tolerant control (FTC) controller is designed and used to maintain a stable purity of 0.9999 (99.99%) in molar fraction, even with actuator faults.

Summary: In this study, a host strain for violacein production from non-sugar feedstocks, Methylorubrum extorquens AM1, was engineered using metabolic engineering. The results showed that by optimizing expression vectors and inducer concentrations, violacein production using methanol as the sole substrate was achieved. Random mutagenesis and site-directed mutagenesis further improved the production, and co-utilization of methanol and acetate significantly enhanced violacein production. This research provides a platform for economically efficient large-scale fermentation system for violacein production.

Summary: A syntrophic process utilizing methanotrophs and oxygenic photogranules (OPGs) was developed to produce polyhydroxy-beta-butyrate (PHB) from a gas stream containing CH4 and CO2 without external oxygen supply. The role of O2 in the synergy was confirmed and M. trichosporium OB3b with OPGs was selected for methane conversion and PHB production. Nitrogen limitation stimulated PHB accumulation in methanotrophs but hindered the growth of the syntrophic consortium. Under a nitrogen source concentration of 2.9 mM, 1.13 g/L of biomass and 83.0 mg/L of PHB could be obtained from simulated biogas. These results demonstrate the efficient conversion of greenhouse gases into valuable products through syntrophy.

Summary: Pyrolysis, a thermal decomposition technique, can extract transportable liquids from lignocellulosic biomass. However, the hydrophilic products of pyrolysis have undesirable characteristics, necessitating additional upgrading processes. Biological methods can address these drawbacks by utilizing hydrophilic compounds as carbon sources under mild conditions. This review investigates the potential of bioconversion routes for upgrading the aqueous phase of pyrolysis oil, considering the presence of toxic compounds and the complex composition of the aqueous phase.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
