Polyhydroxyalkanoates production from a waste-derived feedstock driven by the r...

In the last years, the production of plastics at large-scale has been an issue of great concern due to their environmental and health impacts. Biobased and biodegradable plastics, such as polyhydroxyalkanoates (PHA), have emerged as a possible more ecological and sustainable alternative to those conventional plastics. PHA can be produced by mixed microbial cultures (MMC) from waste-based feedstocks. This work a...

Acidogenic fermentation of brewers’ spent grain monitored through two-dimension...

Biological systems are commonly controlled and monitored through offline and time-consuming tools, which often impairs an effective and real-time response to counteract system disturbances. The feasibility of using two-dimensional (2D) fluorescence spectroscopy as a non-invasive, non-destructive, and real-time procedure to monitor the acidogenic fermentation of brewer’s spent grain (BSG) in a granular sludge re...

The microbiome of anaerobic granules during volatile fatty acid production is s...

Polyhydroxyalkanoates from industrial cheese whey: production and characterizat...

The composition of polyhydroxyalkanoate (PHA) monomers affects the properties and final applications of PHA polymers. This study focused on the feasibility of producing tailored PHA differing in hydroxyvalerate (HV) content, through manipulation of the acidogenic fermented stream composition, and on the characterization of PHA properties to determine the best composition for melt processing. Cheese whey was use...

How does knowledge on the microbiome can help advancing the valorization of bre...

Fluctuations of the pH shape the microbiome of anaerobic granules during volati...

Valorization of brewery waste through polyhydroxyalkanoates production supporte...

Raw brewers’ spent grain (BSG), a by-product of beer production and produced at a large scale, presents a composition that has been shown to have potential as feedstock for several biological processes, such as polyhydroxyalkanoates (PHAs) production. Although the high interest in the PHA production from waste, the bioconversion of BSG into PHA using microbial mixed cultures (MMC) has not yet been explored. Thi...

A two-stage process for conversion of brewer’s spent grain into volatile fatty ...

This work is focused on the valorization of brewer’s spent grains (BSG) into volatile fatty acids (VFA) through acidogenic fermentation. VFAs are building blocks for several applications, such as bioplastics’ production. Using acid hydrolysis as pre-treatment, several batch assays were performed and the impact of organic load (OL) and pH on VFA production from BSG hydrolysate was assessed. Regardless of the con...
