This study aimed to perform an in-depth investigation of olive oil mill wastewater (OOMW). Two OOMW samples (OOMW-A and OOMW-B) from conventionally farmed olives were collected two different mills in Palermo province (Italy). Multiresidual analysis indicated that both unsuitable for food production due pesticide residues. Specifically, OOMW-A contained 4 active compounds totaling 5.7 μg/L, while OOMW-B had 16 analytes with a total content 65.8 μg/L. However, polyphenol the revealed 23 high concentrations hydroxytyrosol, secoiridoid derivatives, phenolic acids, flavones, ranging 377.5 μg/mL (for 391.8 OOMW-A). The microbiological only detectable viable bacteria (102 CFU/mL) lactic acid (LAB) group. distinct LAB strains, Lactiplantibacillus plantarum OMW1 Leuconostoc mesenteroides OMW23, identified. These strains demonstrated notable acidification capabilities produced antibacterial compounds. In conclusion, despite polyphenolic suitability OOMW, presence micro-contaminants hinders their use production. Thus, further studies are underway investigate organically bakery product functionalization, employing selected resistant polyphenols as leavening agents.

Metabolic pathways to sustainability: review of purple non-sulfur bacteria potential in agri-food waste valorization

Frontiers in Bioengineering and Biotechnology, Год журнала: 2025, Номер 13

Опубликована: Фев. 24, 2025

Agri-food waste (AFW) represents a significant fraction of the material generated by agri-food industry, which itself accounts for almost one-third annual global anthropogenic greenhouse gas (GHG) emissions. Considering growing population and consequent rise in food demand, management valorization this are essential to ensure sustainability entire chain future generations. Recycling offers promising strategy mitigate sector's environmental impact, particularly when consists food-grade materials that enhance its intrinsic value. Retaining such products within converting them into feed or food, process referred as "waste upcycling," is therefore critical importance. Purple non-sulfur bacteria (PNSB) emerging candidates AFW upcycling due their remarkable metabolic versatility, allows metabolize wide range organic substrates, including carbohydrates, volatile fatty acids (VFAs), alcohols, valuable microbial biomass. This biomass notably rich superior quality proteins, vitamins, pigments, other high-value compounds. The phototrophic metabolism PNSB advantageous matter valorization, carbon conversion yield approaches unity utilizing light an energy source. review explores potential streams derived from various sources, fruit vegetable residues, well effluents dairy, brewery, sugar industries. pre-treatment methods required optimize substrate availability also discussed. Furthermore, we examine pathways utilized under conditions assimilate most common substrates found AFW, highlighting gaps our understanding metabolism. Additionally, challenges opportunities with focus on applications, identified. underscores recent advancements ongoing challenges, emphasizing role driving sustainable circular bioeconomy applications AFW.
