An efficient system for the fast and efficient purification of transglutaminase from recombinant Streptomyces platensis and expressed in Streptomyces lividans 25-2 is described. Because the purification procedure of this system is flexible, culture broth from laboratory (20 l) and pilot-plant (130 l) fermentations were used to purify the enzyme to electrophoretic homogeneity with high purity (90-95%) and yield (61-77%) within 1 or 2 days.

Background: Tuberculosis (TB) is a global problem that seriously jeopardizes human health. Among them, the diagnosis and treatment of smear- or culture-negative TB patients is a challenge. The Xpert MTB/RIF (Xpert) assay has been reported to be a novel molecular diagnostic tool for rapidly detecting TB.

Recycling of protein-rich environmental wastes and obtaining more valuable products from these recycled products is a topic of interest for researchers. This study aims to produce, purify, and characterize the physicochemical and structural properties of the protease enzyme produced from Brevibacillus agri SAR25 using salmon fish waste as substrate and also to evaluate the effect of protease on the chicken feather, enzyme-ligand interactions, and active site surface area. The production of protease was optimum on 50 g/L fish waste, pH 8, 40 °C, 96 h, and 150 rpm.

Impedance-based biosensing has emerged as a critical technology for high-sensitivity biomolecular detection, yet traditional approaches often rely on bulky, costly impedance analyzers, limiting their portability and usability in point-of-care applications. Addressing these limitations, this paper proposes an advanced biosensing system integrating a Silicon Nanowire Field-Effect Transistor (SiNW-FET) biosensor with a high-gain amplification circuit and a 1D Convolutional Neural Network (CNN) implemented on FPGA hardware. This attempt combines SiNW-FET biosensing technology with FPGA-implemented deep learning noise reduction, creating a compact system capable of real-time viral detection with minimal computational latency.

Green chemistry focuses on reducing the environmental impacts of chemicals through sustainable practices. Traditional methods for extracting bioactive compounds from leaves, such as hydro-distillation and organic solvent extraction, have limitations, including long extraction times, high energy consumption, and potential toxic solvent residues. This study explored the use of supercritical fluid extraction (SFE), pressurized liquid extraction (PLE), and gas-expanded liquid (GXL) processes to improve efficiency and selectivity.
