Structure and Function of Microbial Lipases
Lipases or triacylglycerol acyl hydrolases (EC 3.1.1.3) are ubiquitous in all realms of life. In nature, they are mainly characterized by catalyzing the hydrolysis of triglycerides and long-chain partial glycerides, releasing fatty acids, monoglycerides and glycerol. These enzymes constitute a key link in the cellular processes related to the absorption, release and metabolism of fats, since its substrates and derivatives are the most abundant lipids in cells. On the other hand, some lipases have also been attributed functions as defense enzymes or as virulence factors.  The main aspects of the structure–function of microbial lipases, reviewed more extensively in other articles, will be summarized in a general way, but, here, emphasis will be placed on aspects to be discussed in later sections such as their immobilization and applications in reactions of interest in the production of compounds related to APIs.

Extracellular Vesicles Mediated Regulation
Small noncoding RNAs (sRNA) appear to play a key role in extracellular vesicle (EV)-mediated information transfer. Within the vesicular envelope, RNAs are well protected from degradation and can be shuttled between individuals from one and the same species and beyond. Various communication routes have been discovered such as mother-infant-interaction via breast milk, diverse host-pathogen-relations, and dietary uptake of food derived EVs, proving that EV-mediated inter-kingdom regulation is more than a random event.

Mycorrhizal Symbiosis of Ericaceous Plants
Ericaceae are a group of plants with biotechnological and commercial importance. These plants establish symbiotic associations with a wide group of mycorrhizal fungi. National and global studies have focused on two of them: arbuscular endomycorrhizae and ectomycorrhizae. The classification of mycorrhizae by type of infection described so far in Ericaceae includes ectomycorrhizae, ectendomycorrhizae, and endomycorrhizae. Ectendomycorrhizas can be of arbutoid, monotropoid, and cavendishioid types; endomycorrhizas are of ericoid and arbuscular types. Of these clades, ectomycorrhizas and ectendomycorrhizas (arbutoid, monotropoid, and cavendishioid) form a multilayer mantle of hyphae around the root; while ericoid, unlike the previous ones, develop their intra- and intercellular structures.

Plant Stress Detection by Thermography
Leaf and canopy temperature is a valuable indicator of the physiological status of plants, responding to both biotic and abiotic stressors. Thermography, often combined with other imaging sensors and data-mining techniques, is crucial in the implementation of a more automatized, precise and sustainable agriculture.

Fungi in the Cocoa Production
The role of fungi in cocoa crops is mainly associated with plant diseases and contamination of harvest with unwanted metabolites such as mycotoxins that can reach the final consumer. However, they can be play a positive role as endophytic promoting plant protection and growth; in addition they could play an important role in the fermentation step providing extracellular enzymes important to the pulp bean degradation.

Bioactive Flavonoids from Citrus Fruits
Citrus species are one of the world’s popular fruit crops, cultivated all over the world for their economic and nutritional values. Citrus, like other fruits and vegetables, are an important source of several antioxidant molecules (polyphenols, ascorbic acid, and carotenoids) that can inhibit the harmful effects of free radicals on the human body; due to their functional values and health-promoting properties, Citrus species are considered valuable fruits not only in agri-food industry, but also in pharmaceutical industry. Flavonoids are among the major constituents of polyphenols found in different parts of Citrus fruits (skin, peels, seed, pulp membrane, and juice). Flavonoids have different biological properties (antiviral, antifungal, and antibacterial activities). Several studies have also shown the health-related properties of Citrus flavonoids, especially antioxidant, anticancer, anti-inflammation, anti-aging, and cardiovascular protection activities.

3D-LC
Three-dimensional liquid chromatography (3D-LC) is the consecutive combination of 3 independent LC techniques to decrease the complexity of proteome digest samples. 3D-LC systems can be performed in an online or offline manner. Ideally, each dimension in a 3D-LC system is completely orthogonal to the others.

Fluorescent Protein-Based Autophagy Biosensors
Autophagy is an important cellular process of self-degradation for dysfunctional or unnecessary molecules and organelles, thus dysregulation of autophagy can be involved in various diseases such as neurodegenerative diseases. To understand complex process of autophagy and the related diseases, various methods have been developed, for example biochemical, chemical, and imaging assays. In particular, fluorescent protein (FP)-based autophagy biosensors allow sensitive and selective monitoring of autophagy progression in live cells. After the discovery of green fluorescent protein (GFP), a variety of FPs has been discovered and engineered which have different physicochemical properties, such as excitation/emission spectra, Stokes shift, maturation rate, stability, photo-reactivity and pH-sensitivity. Advances in fluorescent protein technology and FP-based biosensors enabled the real-time monitoring of cellular and molecular events in live cells with high spatiotemporal resolutions.
