Summary: Polycyclic aromatic hydrocarbons (PAHs) are environmental contaminants associated with carcinogenic, mutagenic, and teratogenic health effects. Analyzing PAHs and their transformation products often requires extensive sample preparation and analytical techniques. Excitation-emission matrix (EEM) fluorescent spectroscopy with parallel factor analysis (PAR-AFAC) is a method that eliminates the need for extensive sample preparation and separation techniques. This study demonstrates the use of EEM-PARAFAC to monitor phenanthrene degradation and formation of metabolites.

Summary: In this study, a BaP-degrading strain named Achromobacter xylosoxidans B-2 was isolated and its degradation ability was explored in mineral salt medium (MSM) and PAH-contaminated soil. The results showed that A. xylosoxidans B-2 could remove 87% of BaP in 15 days in MSM and the average removal efficiency of HMW PAHs in soil was 19.92% after 30-day bioremediation. In addition, the addition of cosubstrates increased the removal efficiency of PAHs.

Summary: This study investigated the key driving factors involved in the cometabolic degradation of tetracycline by Chlorella pyrenoidosa. The results showed that cometabolism improved the performance of microalgae by enhancing the electron transport chain and catalytic enzyme activities. The cometabolic pathways involved de/hydroxylation, de/hydrogenation, bond cleavage, decarboxylation, and deamination. The study also demonstrated that cometabolism reduced the concentration of various antibiotics in reclaimed water.

Summary: Microbial transformations are important for the Se cycle, as they convert Se oxyanions into elemental selenium (Se-0) nanostructures, reducing their solubility and toxicity. Aerobic granular sludge (AGS) has been studied for its ability to efficiently reduce selenite to biogenic Se-0 (Bio-Se-0) and retain it in bioreactors. In this study, selenite removal and Bio-Se-0 biogenesis in different size groups of aerobic granules were investigated. Large granules (>= 0.5 mm) showed rapid and efficient selenite reduction and Bio-Se-0 formation due to better entrapment capabilities. SEM-EDX analysis confirmed the formation of Se-0 spheres and their association with the granules. A bacterial strain, identified as Microbacterium azadirachtae, was found to efficiently reduce selenite under aerobic conditions and immobilize the resulting Bio-Se-0. The findings suggest the potential use of large AGS and AGS-borne bacteria in bioremediation of metal(loid) oxyanions and bio-recovery.

Summary: The main products formed during the cometabolism of 1,4-dioxane by the mixed propanotrophic culture ENV487 were identified in this study. The results showed that formate accounted for 51% of the recovered C-14-labeled compounds, and its identity was confirmed using a formate dehydrogenase assay. Other identified products included acetate, glycerate, glycolaldehyde, ethylene glycol, and glycolate, which represented at least 4% of the recovered C-14 products. All these compounds are readily biodegradable in an aquifer environment, indicating that the endpoint for aerobic cometabolism of 1,4-dioxane by propanotrophs in a mixed culture environment is carbon dioxide.

Summary: Cometabolism refers to the degradation of a contaminant by microorganisms grown on compounds other than the contaminant itself. Aerobic cometabolic degradation of 1,4-dioxane (14D) offers advantages such as the use of widely distributed microorganisms, the ability to treat low concentrations of 14D, and the concurrent degradation of chlorinated co-contaminants. This review summarizes recent studies on these features and novel cometabolism-based approaches for treating 14D and its associated co-contaminants.

Summary: This study found that extracellular vesicles (EVs) released by certain normal vaginal bacteria can protect against HIV-1 infection by inhibiting interactions between the virus and cell receptors. The inhibitory effect is associated with protein components on the surface of EVs, and identifying EV-associated proteins with anti-HIV-1 properties may contribute to the development of novel strategies for preventing HIV-1 transmission.

Summary: This study compares the performance of a nanofiber device and a resin column for antibody capture. The nanofiber device has a larger housing volume and lower binding capacity, but comparable eluate purity to the resin column. It shows high stability, can be used for multiple cycles, and maintains consistent eluate quality when scaled up. The use of a single nanofiber device can significantly reduce costs compared to a resin column, especially when the number of batches is limited.

Summary: Fed-batch cell culture processes are commonly used in biomanufacturing due to their simplicity and applicability in cGMP environments. However, the challenge lies in the changing physiochemical conditions within the bioreactor as the cell density changes. Traditional response surface models (RSMs) are commonly used for optimization but are limited by their use of time-invariant factors. Dynamic RSM (DRSM) models can predict the time-dependent impact of process inputs, allowing for optimization of process operations that change over time.

Summary: Water for injection (WFI) production in the biopharmaceutical industry consumes excessive amounts of water and energy. Recycling buffers can potentially save up to 90% of resources, but achieving the full theoretical potential is impossible when a risk-aware design is used.

Summary: In this study, heterologous expression and homologous overexpression of ABC transporter proteins AatA and MdlB were found to improve butyric acid production in C. tyrobutyricum. The overexpression of these proteins upregulated the expression levels of key enzymes in the acetate synthesis pathway and promoted the synthesis and secretion of acetic acid. Additionally, the increase in ATPase activity facilitated sugar utilization, induced extracellular secretion of acetate, and shortened fermentation periods.
