Summary: Pollution from heavy metals is a significant global environmental concern caused by human activities such as mining, farming, and manufacturing. This pollution can harm crops, disrupt the food chain, and pose a threat to human health. Phytoremediation, a method that uses plants to remove heavy metals, is the most controllable and eco-friendly solution. However, the effectiveness of phytoremediation depends on the bioavailability of heavy metals in soil and the biomass of plants. This study examines different techniques and frameworks for heavy metal removal, emphasizing the challenges and limitations of phytoremediation and its potential application in addressing other harmful pollutants.

Summary: This study examines the use of pristine Mo2C as a sodium persulfate (SPS) activator for the degradation of the drug losartan (LOS). The results show that acidic pH enhances LOS decomposition, and the apparent kinetic constant decreases with higher LOS concentrations. Sulfate radicals, hydroxyl radicals, and singlet oxygen are identified as the reactive species in LOS oxidation, with singlet oxygen being the predominant species. The addition of chloride accelerates the degradation rate, while bicarbonate and organic matter reduce the efficiency. The study also investigates the application of the Mo2C/SPS system for simultaneous LOS decomposition and elimination of Escherichia coli, with significant synergistic effects observed when simulated solar irradiation is present.

Summary: The accumulation of both natural and anthropogenic sources of metals in the ecosystem has led to increasing concerns over heavy metal (HM) pollution. Human exposure to HMs, such as mercury, arsenic, lead, chromium, and cadmium, has become a significant environmental and health issue. These HMs can cause acute or chronic poisoning through water, air, or food. Their bioaccumulation in the body leads to various toxic effects on organs and tissues, primarily through the production of reactive oxygen species, enzyme inactivation, and oxidative stress. Conventional techniques for HM removal are limited, especially when the HM concentration is low. Microbial bioremediation, utilizing organisms like fungi and bacteria, has emerged as a potential solution due to their superior biosorption and bioaccumulation capabilities. This review aims to provide insights into HM uptake, toxicity mechanisms, and the management of metal poisoning through the selection of microbial remediation technology.

Summary: The transition to sustainability and the circular economy is a response to environmental impacts and the need to improve the linear production and consumption model. Biowaste refineries are gaining popularity as an alternative to petroleum refineries. Biowaste is an important source for developing bioproducts and biofuels, and effective environmental management systems are crucial for a circular economy. Bioplastics made from renewable or recycled materials can contribute to more sustainable plastic life cycles. Regulation and financial incentives are needed to scale up bioplastic production for a truly sustainable impact.

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.
