Bioactive Metabolites in Liquid State Cultures
Humans have appreciated mushrooms for their edible and medicinal value since the Neolithic age. Increased interest in the pharmaceutical potential of mushrooms has led to numerous publications that explore more than 100 reported medicinal functions. These are functions such as antifungal, antibacterial, antiviral, antioxidant, anti-inflammatory, anti-tumor, antiviral, anti-diabetic, anti-thrombotic, anti-allergic, antidepressive, antihyperlipidemic, digestive, hypotensive, cytotoxic, hepatoprotective, neuroprotective, nephroprotective, osteoprotective, and immunomodulating activities, among others. This therapeutic action is due to a wide array of bioactive metabolites isolated from the fruiting body, mycelium, and culture broth of macrofungi. Both complex high-molecular-weight compounds such as polysaccharides, proteins, and lipids and low-molecular-weight compounds such as terpenoids, polyketides, and alkaloids have been isolated and are under study. In addition to their pharmaceutical potential, mushrooms are recognized as a rich source of nutraceuticals. Nutraceuticals are substances that have positive effects, proven by clinical testing, on normal physiological functions that maintain health in humans, thus preventing and treating diseases and enhancing longevity. There is a globally growing market for nutraceuticals sold as nutrients and supplements or in the form of enhanced “functional foods”. Natural bioactive compounds found in macrofungi are ideal for this market and are already being used for their properties.

Mega Borg Oil Spill
The Mega Borg Oil Spill occurred in the Gulf of Mexico on June 8, 1990, roughly 50 miles off the coast of Texas , when the oil tanker Mega Borg caught on fire and exploded. The cleanup was one of the first practical uses of bioremediation.

Skeletal Transformations and the Origin of Baleen Whales
Mysticeti or baleen whales are a group of cetaceans including a few extant species in only six genera. Despite their scarce diversity, baleen whales represent key species in the trophic webs of the oceans as they are able to sequester enormous quantities of carbon and to disseminate nutrients that support large planktonic blooms. The study of their evolution is thus crucial to understand how and when the ecological characteristics of today’s oceans came to be.

Studies on Traditional Ecological Knowledge
Traditional ecological knowledge (TEK) dominated by traditional populations, especially fishermen and women, has been the object of scientific research from different perspectives, disseminating information on fauna and flora in different environments. Such interest refers to the importance that the set of information that these populations have on the dynamics of the local environment and the relationship with the environment in which they live. Generally, the transmission of this knowledge happens from generation to generation; however, it is still little valued by studies related to natural sciences. The study of this type of traditional ecological knowledge can support scientific studies and, therefore, help to fill the gaps in the understanding between the relationship between human activities and different ecosystems.

Circular Economy Principles for Biobased Products
To support progress towards the transition to a circular economy, the ability to measure circularity is essential. The consideration of the role biobased products can play in this transition is however still largely lacking in the development of circularity monitoring approaches. The first step in coming to a suitable monitoring framework for biobased products is to define circular economy principles.

The Development of Biogas Plants
Agricultural biogas plants have a long history, beginning with early advancements in biogas technology and its application in agricultural contexts. Throughout history, several societies have used organic waste to make biogas, a renewable energy source. However, modern agricultural biogas plants as we know them today have changed greatly as a result of scientific and technological advances.

Cereal Crop Residues in Green Concrete Technology
Concrete is mainly employed as a construction material. Due to the manufacturing of cement and the extent of concrete usage, numerous environmental issues and water suction have presented challenges. There is an immediate need to overcome these problematic issues by substituting natural resources with wastes and by-products of different biological processes in the production of concrete in order to make green concrete. Green concrete provides a relatively low-impact material to satisfy potential concrete demand and offers a cheaper, robust and highly reliable alternative that could fulfil future construction requirements in an environmentally safer way. Green concrete could be an alternative material that could replace those used in conventional methods of construction and help make a further step towards environmental sustainability and a circular bioeconomy.

MW/UV/TiO2 Photocatalysis Technologies for Organic Wastewater Treatment
Microwave (MW)-induced oxidation and ultraviolet (UV)/TiO2 photocatalytic technologies are widely used for organic wastewater treatment. Furthermore, the combination of these technologies (MW/UV/TiO2) result in a new advanced oxidation process. As a green and efficient photocatalytic degradation technology, MW/UV/TiO2 is favored for its advantages of high removal rate, short time use, wide concentration range, low cost, good stability, and no secondary pollution.
