Enzymatic potential for the valorization of agro-industrial by-products.

Agro-industrial residues and by-products are a crescent environmental problem since they are often discarded without proper treatment, and still have growing production. These residues are rich from a nutritional point of view and contain various industrial relevant compounds, such as phenolic compounds, fibers, vitamins, sugars and others. The crescent worrying about environmental issues has led researchers and industries to focus on "eco-friendly" solutions for everyday problems.

Current status of biotechnological production and applications of microbial exopolysaccharides.

Microbial exopolysaccharides (EPS) are an abundant and important group of compounds that can be secreted by bacteria, fungi and algae. The biotechnological production of these substances represents a faster alternative when compared to chemical and plant-derived production with the possibility of using industrial wastes as substrates, a feasible strategy after a comprehensive study of factors that may affect the synthesis by the chosen microorganism and desirable final product. Another possible difficulty could be the extraction and purification methods, a crucial part of the production of microbial polysaccharides, since different methods should be adopted.

Newly isolated microorganisms with potential application in biotechnology.

Nowadays, food, cosmetic, environmental and pharmaceutical fields are searching for alternative processes to obtain their major products in a more sustainable way. This fact is related to the increasing demand from the consumer market for natural products to substitute synthetic additives. Industrial biotechnology appears as a promising area for this purpose; however, the success of its application is highly dependent of the availability of a suitable microorganism.

The colors of biotechnology: general overview and developments of white, green and blue areas.

Biotechnology is responsible for the manipulation of living organisms or their components for the production of products that are of benefit to human kind. Due to the wide range of applications, colors have been used to differentiate the main areas of research, such as white (industrial), green (agricultural) and blue (marine and fresh-water), among others. Thus, this review outlines the impacts of these areas of biotechnology, emphasizing their impact and potential to replace carbon-based technologies with more sustainable technologies.

Biotransformation of α- and β-pinene into flavor compounds.

Products that bear the label "natural" have gained more attention in the marketplace. In this approach, the production of aroma compounds through biotransformation or bioconversion has been receiving more incentives in economic and research fields. Among the substrates used in these processes, terpenes can be highlighted for their versatility and low cost; some examples are limonene, α-pinene, and β-pinene.
