Article
Full-text available
Spent coffee grounds (SCGs) are a promising substrate that can be valorized by biotechnological processes, such as for short-chain organic acid (SCOA) production, but their complex structure implies the application of a pretreatment step to increase their biodegradability. Physicochemical pretreatments are widely studied but have multiple drawbacks...
Article
Full-text available
Acidogenic fermentation (AF) is often applied to wastes to produce short-chain organic acids (SCOAs)—molecules with applications in many industries. Spent coffee grounds (SCGs) are a residue from the coffee industry that is rich in carbohydrates, having the potential to be valorized by this process. However, given the recalcitrant nature of this wa...

Full-text available
The pulp and paper industry is recognized as a well-established sector, which throughout its process, generates a vast amount of waste streams with the capacity to be valorized. Typically, these residues are burned for energy purposes, but their use as substrates for biological processes could be a more efficient and sustainable alternative. With t...

Fluorescence in situ hybridization (FISH) enables the detection and enumeration of microorganisms in a diversity of samples. Short-length oligonucleotide DNA probes complementary to 16S or 23S rRNA sequences are generally used to target different phylogenetic levels. The protocol for the application of FISH to aggregated or suspended cells in mixed...
Article
Polyhydroxyalkanoates (PHAs) are biodegradable plastics of microbial origin, whose biodegradability and thermochemical properties make them greener alternatives to conventional plastics. Despite their high industrial potential, the PHAs’ high production costs still hinder their application. Mixed microbial biomass combined with agro-industrial wast...
Article
Pulp and paper factories produce several residues that can be explored and valorized through polyhydroxyalkanoate (PHA) production via a three-step process. The objective of this work was focused on the selection step. Acidified hardwood spent sulfite liquor (HSSL), a fermented waste stream from a pulp and paper factory, was used to select a mixed...
