Valorisation of olive oil by-products into pectic- and glucuronoxylo-oligosacch...
Cordeiro, Ana; Fernandes, Andreia; Ferreira, Andreia S.; Coelho, Elisabete; Coimbra, Manuel A.; Silvério, Sara C.; Cadavez, Vasco; Peres, António M.Olive pomace (OLP) and stones (OLS) are key by-products of olive oil production, rich in lignocellulose and pectin, making them viable substrates for prebiotic oligosaccharide (OS) production. This study evaluated the chemical composition of OLP and OLS powders (OLPp and OLSp) and their potential for OS production through one-step fermentation using recombinant Bacillus subtilis 3610. Both substrates had compar...

Different approaches to Olive Pomace valorisation
Cordeiro, Ana; Lamas, Sandra; Rodrigues, Ana; Cadavez, Vasco; Silvério, Sara; Peres, António M.; Rodrigues, Lígia R.; Amorim, CláudiaOlive pomace (OP) is a substantial by-product, rich in lignocellulosic materials and water, obtained following the extraction of olive oil. It comprises the following components: olive skins, pulp, seeds, and stones. As global olive oil production continues to rise, the management and utilisation of OP have become increasingly important from both an economic and an environmental perspective [1]. In this study, ...
Olive oil by-products as potential alternative substrates for xylooligosacchari...
Cordeiro, Ana; Fernandes, Andreia; Peres, António Manuel; Rodrigues, L. R.; Amorim, CláudiaOlive pomace (OP) and olive stones (OS) are industrial by-products from the olive oil production. These residues have a high percentage of cellulose, hemicellulose, and lignin, which makes them a good source of fermentable sugars and xylan, as well as a potential alternative substrate for xylooligosaccharides (XOS) production. In this work, OP and OS were chemically characterized and used for the first time as ...

Cordeiro, Ana; Fernandes, Andreia; Sousa, Joana; Cardoso, Beatriz; Alves, Joana; Silvério, Sara; Peres, António M.; Rodrigues, Lígia R.; Amorim, CláudiaThe prebiotic effect is a fundamental concept in the fields of nutrition and gut health, referring to the beneficial effects of specific non-digestible dietary components on the gut microbiota, including xylooligosaccharides (XOS). These compounds function as food sources for beneficial gut bacteria, fostering their growth and activity. In this work, in vitro studies were performed to evaluate the prebiotic pot...
Tailoring fructooligosaccharides composition with engineered Zymomonas mobilis ZM4
Braga, Adelaide; Gomes, Daniela Filipa Correia; Costa, João Manuel Rainha; Cardoso, Beatriz; Amorim, Cláudia; Silvério, Sara Isabel CruzZymomonas mobilis ZM4 is an attractive host for the development of microbial cell factories to synthesize high-value compounds, including prebiotics. In this study, a straightforward process to produce fructooligosaccharides (FOS) from sucrose was established. To control the relative FOS composition, recombinant Z. mobilis strains secreting a native levansucrase (encoded by sacB) or a mutated -fructofuranosidas...
Engineering Saccharomyces cerevisiae for the one-step production of a functiona...
Amorim, Cláudia; Rodrigues, Joana Lúcia Lima Correia; Braga, Adelaide; Gomes, Daniela Filipa Correia; Costa, João Manuel RainhaFructooligosaccharides (FOS) are recognized prebiotics with proven beneficial effects, usually produced by two-step processes. In this work, an in vivo bioprocess was developed for the one-step production of a functional sweetening mixture containing FOS. Sucrose was directly fermented by yeast towards process simplification and cost reduction. Saccharomyces cerevisiae YIL162W lacking the gene responsible for s...
Novel and emerging prebiotics: Advances and opportunities
Cardoso, Beatriz B.; Amorim, Cláudia; Silvério, Sara Isabel Cruz; Rodrigues, L. R.Consumers are conscientiously changing their eating preferences toward healthier options, such as functional foods enriched with pre- and probiotics. Prebiotics are attractive bioactive compounds with multidimensional beneficial action on both human and animal health, namely on the gastrointestinal tract, cardiometabolism, bones or mental health. Conventionally, prebiotics are non-digestible carbohydrates which...
