Pre-metabolic syndrome (pre-MetS) may represent the best transition phase to start treatments aimed at reducing cardiometabolic risk factors of MetS. In this study, we investigated the effects of the marine microalga F&M-M36 () on cardiometabolic components of pre-MetS and its underlying mechanisms. Rats were fed a standard (5% fat) or a high-fat diet (20% fat) supplemented or not with 5% of or fenofibrate (100 mg/Kg) for 3 months.

This study investigated the effects of varying iron concentrations (1, 5, and 10 mg L) in the culture media on the biochemical composition and the iron bioaccumulation and speciation in F&M-C256. Iron content measured in biomasses varied from 0.

We studied the LAF of as the sole substrate using as the starter culture. Fermented (FB) and non-fermented broth (NFB) were analysed by means of pH, lactic acid bacteria (LAB) count, lactic acid concentration, microbiological safety, and nutritional composition.

Food security will therefore represent a matter of global concern not easily tackled with current agriculture practices and curbed by the increasing scarcity of natural resources and climate change. Disrupting technologies are urgently needed to improve the efficiency of the food production system and to reduce the negative externalities of agriculture (soil erosion, desertification, air pollution, water and soil contamination, biodiversity loss, etc.

The purpose of this pioneering work was to analyze the broad-spectrum effects of the F&M-C256 extract on L. cv.

After 72 h of fermentation, a bacterial concentration of about 10.5 log CFU mL in the broths containing the soybean drink + spirulina + LAB8014 (SD + S + LAB8014) or water + spirulina + LAB8014 (W + S + LAB8014) was found.

Sourdough was used as leavening and fermentation agent and three concentrations of A. platensis F&M-C256 were tested: 2%, 6% and 10% (w/w).

In the present work, the dried biomasses of four microalgae strains- F&M-C256, Allma, F&M-M33, and F&M-M40-were used as a source of proteins, antioxidants, and other bioactive molecules in artisanal wheat crackers. Two incorporation levels were tested: 2% () and 6% ().

However, the effect of these extracts on secondary metabolism compounds, that are fundamental for grape and wine quality, is still scarce. In the present study, the effects of foliar treatments with an Ascophyllum nodosum extract on physiological and biochemical parameters of Vitis vinifera (cv.
