This paper is a review of the potential of olive pomace, a by-product of the olive sector, as a precursor for the production of biochar. In general, it presents a panorama of this sector, which is so important worldwide and particularly in the Mediterranean region, the largest olive and olive oil producing area in the world, representing 90% of global production. We also address the problem of the large amount of waste (around 15 million tons/year), in the form of pomace, generated by this olive oil production ind...

Mycotoxins are agents with different and complex chemical structures, with toxic effects for humans and animals. They can be present in feed and food, although in very small quantities, mycotoxins have a negative effect on the health of animals and people. Ochratoxins are mycotoxins intensively studied in recent years due to their toxicity on the animal and human body; these toxins show nephrotoxic, immunotoxic and myelotoxic, neurotoxic and carcinogenic effects. Thirty male rats of the Sprague- Dawley breed were ...

A genuine and urgent need is to prevent and treat bacterial diseases primarily caused by germs that have developed antibiotic resistance. These factors led to several studies focusing on alternate or supplementary antimicrobial methods. With the expectation that, unlike antibiotics, they will be effective without causing resistance, researchers are becoming increasingly interested in antimicrobial substances made from natural resources, such as plant extracts, essential oils, and peptides. The present study invest...

CRISPR-Cas adaptive immunity systems of prokaryotes have been identified in 42% of bacteria and 85% of archaea [1] and are actively used in genetic engineering. However, in nitrogen-fixing nodule bacteria required for agriculture, these systems are very poorly characterized.
