Azospirillum baldaniorum Sp 245 is a model plant growth-promoting rhizobacterium. The first cross-talk with plants takes place within the roots. Roots cells growth is constrained by the primary cell wall (CW).
Olive pomace, a byproduct of olive oil production, is rich in beneficial compounds and was tested in a study involving 62 participants with high cholesterol, who consumed olive pomace-enriched biscuits for 8 weeks.
The study found no significant changes in the overall diversity of gut microbiota or cardiovascular disease markers, but a tendency towards reduced oxidized LDL cholesterol and increased bifidobacteria was observed in those consuming the biscuits.
Ingestion of these biscuits increased certain phenolic acid levels in urine and blood, indicating a metabolic change in gut bacteria, with noticeable differences between male and female participants.
