Summary: In this study, the woody stem of Moringa oleifera was pretreated using a combination of chipping, milling, nitric acid, and autohydrolysis. The pretreated hydrolysate was then subjected to simultaneous saccharification and fermentation (SSF) using Zymomonas mobilis and Kluyveromyces marxianus. By optimizing the fermentation process parameters, K. marxianus achieved the highest concentration of cellulosic ethanol after a fermentation period of 96 hours.

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. Universal risk-based assessment is important for regulatory authorities to consider the implementation of such a strategy.

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.
