Growth, oxidative stress, and intermediary metabolism of European seabass (Dice...

Previous research demonstrated that solid-state fermentation (SSF) of distiller's dried grains with solubles (DDGS) by Aspergillus ibericus improved protein, reduced neutral and acid detergent fiber levels, and added phenolic compounds, xylanase, and cellulase. Fermentation of DDGS also increased protein, lipids, energy, and starch digestibility. This study evaluated the effects of unfermented and fermented DDG...

Effects of solid-state fermentation of Gelidium corneum by-product on immune st...

It was previously observed that dietary inclusion of 10 % Gelidium corneum by-product and sunflower cake mixture (1:1 ratio; Gmix), replacing corn gluten meal, reduced feed utilization efficiency in European sea bass juveniles, while the same mixture fermented with Aspergillus ibericus restored feed efficiency as well as nitrogen and energy utilization, achieving levels comparable to the control diet. The prese...

Fermented brewer's spent grain as a sustainable feed ingredient impacts meagre ...

It was previously observed that solid-state fermentation (SSF) with Aspergillus ibericus increased brewer's spent grain (BSG) protein content (21%) while reducing lipid (49%), cellulose (30%), hemicellulose (34%), and lignin (7.3%) contents. This study evaluated the potential of fermented BSG (BSG-SSF) as a novel feed ingredient for meagre (Argyrosomus regius) juveniles by evaluating growth performance, digesti...

Yarrowia lipolytica uses olive tree prunings hydrolysates for microbial lipids ...

Efficiently valorizing olive tree prunings (OTP) for microbial lipids represents an excellent strategy to achieve resource circularity, accompanied by economic and environmental benefits. Since the production of lipids from OTP hydrolysate (OTPH) by yeasts remains underexplored, this study investigated the potential of Y. lipolytica to produce lipid-rich biomass in bioreactor batch cultures. OTP was fractionate...

Effect of solid-fermented brewers spent grain on growth, metabolism, and oxidat...

Replacing traditional agricultural ingredients with biotechnologically improved agro-industry by-products in fish diets promotes sustainable aquaculture, reduces production costs and carbon footprint, and promotes a circular economy. Brewers spent grain (BSG) is one such by-product. Solid-state fermentation (SSF) of BSG with Aspergillus ibericus enhances its nutritional value and digestibility for European seab...

Effect of ohmic heating pretreatment on enzyme production by solid-state fermen...

Solid-state fermentation (SSF) involves the growth of microorganisms on solid substrates, mimicking natural environments of many species. Due to sustainability concerns, transforming agro-industrial by-products into value-added products through SSF has been increasingly studied. Brewers spent grain (BSG), the main by-product of beer production, mostly consists of barley grain husks, making BSG a great support f...

Transforming orange and banana peels fermented with Yarrowia lipolytica into nu...

Alternative feedstocks for high-quality biodiesel: Lipid production from eucaly...

ABSTRACT: Microbial lipids produced by yeasts from lignocellulosic biomass are a promising feedstock for the biodiesel industry, providing a renewable energy source as an alternative to traditional fossil fuels. This study investigated the potential of Yarrowia lipolytica W29 to produce lipid-rich biomass from undetoxified sugar-concentrated eucalyptus bark hydrolysate (EBH). The lipid concentrations achieved i...

Leveraging fermented fruit peels with Yarrowia lipolytica to develop innovative...

Consumers are increasingly concerned about the nutritional value, safety, and sustainability of new food products. As awareness of health and environmental issues grows, they seek options that provide essential nutrients while being free from harmful additives and produced in environmentally responsible ways. The search for healthier diets has instigated the exponential growth of the plant-based food industry. ...
