There is a current tendency towards bioactive natural products that can be used in different areas such as food, pharmaceutical, and biomedical. In the last decades, polysaccharides have attracted increasing interest because of their potent nontoxic effects, therapeutic properties, and diversified range of applications. Polysaccharides are complex and heterogeneous macromolecules constituted of different monosaccha Read More

The world is on the cusp of a post-antibiotic period. A century ago, before the advent of antibiotics, bacteriophage therapy was the treatment of choice for bacterial infections. Although bacteriophages have yet to be approved as a treatment in Western medicine, researchers and clinicians have begun to anticipate phage therapy. Bacteriophages are viruses that depend on bacterial cell metabolism to multiply. They offer a p Read More

Background: Rubella, caused by the Rubella virus (RV), is considered a mild self-limited illness. However, RV has teratogenic potential. Laboratory investigation plays an important role in both diagnosis and surveillance of the disease. The main methods for diagnosing Rubella are serological assays for the detection of specific IgM and molecular assays for detecting viral RNA. However, some laboratories perform IgG avidity te Read More

Proteases that perform keratin hydrolysis (keratinases) have great potential in biotechnology. After investigation, the next step to an industrial application is protecting intellectual property by patenting. There are many fields of discovered keratinase implementation dictated by features of the molecule and its producer. This article provides an overview of existing patents on keratinases. Among the patents found using term Read More

Background: Interest in natural pigments has grown due to the negative aspects caused by synthetic options, which trigger damage to the body and the environment. Research with natural pigments produced by microorganisms becomes viable in relation to other pigments extracted from animals or plants, as microorganisms have advantages in terms of versatility and productivity. Thus, production technologies are protect Read More

Background: Biosurfactants are natural bioactive compounds produced from fungi, bacteria and plants.
