Enzymatic Biocatalysts Applied for Pharmaceutical Pollutants Degradation
Both the growth of the world’s population and the associated active use of various pharmaceutical compounds (PCPs) (antibiotics, hormones, cardiovascular, analgesics, , anti-inflammatory and antiepileptic drugs, etc.) have led to the problem of their contamination of water and the environment. PCPs are found in various concentrations in the wastewater of urban wastewater treatment plants. The physical-chemical processes of PCPs removal using membrane filtration, chlorination, ozonation and photocatalytic oxidation, sorption and microbiological degradation ensure the elimination of these pollutants, but have certain limitations in the effectiveness of these processes.Biological treatment has a number of significant advantages, which consist in the use of natural biocatalysts (enzymes, microorganisms) for the destruction of micropollutants. Analysis of recently published studies on the use of soluble and immobilized enzymes as biocatalysts for the biodegradation of various PCPs has shown the effectiveness of these applications.

Heterologous Host for Alternative Production of Amaryllidaceae Alkaloids
Amaryllidaceae alkaloids (AAs) are plant specialized metabolites with therapeutic properties exclusively produced by the Amaryllidaceae plant family. Bioengineered microbial hosts that grow rapidly can produce plant target specialized metabolites faster as compared to whole plant systems. In addition, the production of plant metabolites in heterologous hosts can reduce downstream extraction process, which eventually becomes more economically sustainable. For the successful synthesis of plant metabolites such as AAs, heterologous hosts require the introduction of reconstructed biosynthetic pathway, requiring key enzymes. This requires comprehensive knowledge of the enzymatic reactions involved in the biosynthesis of the compound of interest in the native host organisms (i.e., plants).

Monkeypox Diagnosis Approaches
Monkeypox virus (MPXV) is an adenovirus with a double-stranded DNA genome, belonging to the family Poxviridae, subfamily Chordopoxvirinae, and the genus Orthopoxvirus. MPXV was first reported in 1958 after two pox-like disease outbreaks occurred in monkeys. The original source of MPXV is unknown. Rodents likely harbor the virus, leading to spillover events. The case of human infection by MPXV was first reported in humans in in the Democratic Republic of the Congo in 1970.

Secretome Proteomic Approaches
Searching for new cancer-related biomarkers is a key priority for the early detection of solid tumors, such as colorectal cancer (CRC), in clinically relevant biological fluids. The cell line and/or tumor tissue secretome represents a valuable resource for discovering novel protein markers secreted by cancer cells. The advantage of a secretome analysis is the reduction of the large dynamic range characterizing human plasma/serum, and the simultaneous enrichment of low abundance cancer-secreted proteins, thereby overcoming the technical limitations underlying the direct search in blood samples.

Synthesis, Characterization, and Applications of Bioactive Metallic Nanoparticles
Nanoparticles (NPs) are elements derived from a cluster of atoms with one or more dimensions in the nanometer scale in the range of 1–100 nm. The bio nanofabrication of metallic NPs is now an important dynamic area of research, with major significance in applied research. Biogenic synthesis of NPs is more desirable than physical and chemical synthesis due to its eco-friendliness, non-toxicity, lower energy consumption, and multifunctional nature. Plants outperform microorganisms as reducing agents as they contain large secondary biomolecules that accelerate the reduction and stability of the NPs. The produced NPs can then be studied spectroscopically (UV-Visible, XRD, Raman, IR, etc.) and microscopically (SEM, TEM, AFM, etc.). The biological reduction of a metallic ion or its oxide to a nanoparticle is quick, simple, and maybe scaled up at room temperature and pressure. The rise in multi-drug resistant (MDR) microbes due to the immoderate use of antibiotics in non-infected patients is a major cause of morbidity and mortality in humans. The contemporary development of a new class of antibiotics with different mechanisms of action to kill microbes is crucial. Metals and their oxides are extremely toxic to microbes at unprecedentedly low concentrations. In addition, prevailing infections in plants and animals are raising significant concerns across the globe. NPs’ wide range of bioactivity makes them ideal antimicrobial agents in agricultural and medical fields. The present research outlines the synthesis of metallic NPs from botanicals, which enables the metals to be in a stabilized form even after ionization. It also presents a valuable database on the biofunctionalization of synthesized NPs for further drug development.

Anticancer Secondary Metabolites of Astragalus Species
Some of the most effective anticancer compounds are still derived from plants since the chemical synthesis of chiral molecules is not economically efficient. Rapid discovery of lead compounds with pronounced biological activity is essential for the successful development of novel drug candidates. The genus Astragalus L. is the largest in the family Fabaceae (syn. Leguminosae), with more than 3500 species. Astragalus, excluding Astracantha (formerly Astragalus subgenus Tragacantha), has a world total of ca. 2500 species, of which ca. 500 are in the Americas. Many of the species have conservation status “vulnerable” or “critically endangered”.

Co-Inoculation of three species
The adoption of multi-species starter cultures is highly considered in modern winemaking to enhance the complexity and wine attributes. However, the valuation of strains compatibility at the industrial-scale is essential to guarantee the quality and the safety during the process. This concept is particularly important when the starter is composed of non-Saccharomyces, Saccharomyces spp. and malolactic bacteria, three organisms with dissimilar biological properties and oenological implication.

Glycoside Hydrolases and Glycosyltransferases from Hyperthermophilic Archaea
Hyperthermophilic Archaea colonizing unnatural habitats of extremes conditions such as volcanoes and deep-sea hydrothermal vents represent an unmeasurable bioresource for enzymes used in various industrial applications. Their enzymes show distinct structural and functional properties and are resistant to extreme conditions of temperature and pressure where their mesophilic homologs fail. In this review, we will outline carbohydrate-active enzymes (CAZymes) from hyperthermophilic Archaea with specific focus on the two largest families, glycoside hydrolases (GHs) and glycosyltransferases (GTs). We will present the latest advances on these enzymes particularly in the light of novel accumulating data from genomics and metagenomics sequencing technologies. We will discuss the contribution of these enzymes from hyperthermophilic Archaea to industrial applications and put the emphasis on newly identifed enzymes. We will highlight their common biochemical and distinct features. Finally, we will overview the areas that remain to be explored to identify novel promising hyperthermozymes.

Bioactive Antimicrobial Peptides for Infected Diabetic Foot Ulcers
Diabetic foot ulcer (DFU) is a devastating complication, affecting 15% of diabetic patients and representing the leading cause of non-traumatic amputations. Notably, the risk of mixed bacterial–fungal infection is elevated and highly associated with wound necrosis and poor clinical outcomes. Antimicrobial peptides (AMPs) are endogenous peptides that are naturally abundant in several organisms, such as bacteria, amphibians and mammals. These molecules have shown broad-spectrum antimicrobial activity and some of them even have wound-healing activity, establishing themselves as ideal candidates for treating multi-kingdom infected wounds.

Engineering of GH11 Xylanases for Optimal pH Shifting
Endo-1,4-β-xylanases belonging to the glycoside hydrolase (GH) 11 family hydrolyze the β-1,4-glycosidic linkages in the xylan backbone to convert polymeric xylan into xylooligosaccharides. GH11 xylanases play an essential role in sugar metabolism and are one of the most widely used enzymes in various industries, such as pulp and paper, food and feed, biorefinery, textile, and pharmaceutical industries. pH is a crucial factor influencing the biochemical properties of GH11 xylanase and its application in bioprocessing. For the optimal pH shifting of GH11 xylanase in industrial applications, various protein engineering studies using directed evolution, rational engineering, and in silico approaches have been adopted.
