Bacteria, fungi, and algae are examples of microorganisms that synthesize polysaccharides, which are macromolecules that belong to the carbohydrate class. Production of polysaccharides represents an alternative to chemical and plant-derived compounds that could be used for human well-being which requires implementation of different methods standardized during the extraction and purification process. In the current investigation, Pseudolagarobasidium acaciicola, a novel fungal source of exopolysaccharide (EPS) was used which produced 2773.

Biological control, which utilizes nematophagous fungi to reduce gastrointestinal nematode populations, may effectively diminish the need for chemical anthelmintic treatments. However, the limited knowledge surrounding the mass production of chlamydospores hinders the widespread use of biological products as alternatives to traditional anthelmintics. This study aimed to evaluate the development of liquid culture media for the large-scale production of the nematophagous fungi Duddingtonia flagrans using a systematic procedure, progressing from microplates to bioreactor.

Plant responses to the water environment are mediated by ethylene (submergence response) and abscisic acid (ABA, drought response). Ethylene is perceived by a family of histidine kinase receptors (ETR-HKs), which regulate the activity of the downstream B3 Raf-like (RAF) kinase CONSTITUTIVE TRIPLE RESPONSE1 (CTR1) in an ethylene-dependent manner. We previously demonstrated in the moss Physcomitrium patens that SNF1-related protein kinase 2 (SnRK2), an essential kinase in osmostress responses in land plants, is activated by the B3-RAF kinase ARK, which is also regulated by ETR-HKs in an ABA- and osmostress-dependent manner.

Although vinegar is a product obtained by a well-known bioprocess from a technical point of view, the complex microbiota responsible for its production and their involvement in the organoleptic profiles are not clear yet. In this work, three acetification profiles in submerged culture using both synthetic and raw materials from Andalusia (Spain) were characterized by metagenomic (16S rRNA amplicon sequencing) and metabolomic tools (stir-bar sorptive extraction with thermo-desorption coupled to gas chromatography-mass spectrometry (SBSE-TD-GC-MS) and high-performance liquid chromatography (HPLC)). A total of 29 phyla, 208 families, and many more genera were identified, comprising bacteria and archaea as well as 75 metabolites, including minor volatile compounds, amino acids, biogenic amines, and other nitrogenous compounds.
