TL;DR: In this paper, the authors provided an overview regarding coffee and its main industrial residues, including coffee silverskin and spent coffee grounds, obtained during the beans roasting and the process to prepare instant coffee, respectively.

TL;DR: The aim of this review is to focus on the production and extraction of bioactive phenolic compounds from natural sources by SSF, and the characteristics of SSF systems and variables that affect the product formation by this process are reviewed.

TL;DR: In this paper, the authors used methanol as solvent at different concentrations (20-100%), solvent/solid ratios (10-40 ml/g SCG), and extraction times (30- 90 min), and evaluated the influence of these operational variables on the content of total phenolic compounds and antioxidant activity of the produced extracts.

TL;DR: In this article, the authors evaluated the efficacy of different solvents (methanol, ethanol, acetone, hexane, ethyl acetate, water, methanol:water mixtures, ethanol: water mixtures) for extracting antioxidant phenolic compounds from brewer's spent grains (BSGs).

TL;DR: This study provides a more accurate comparison between the antibiotic susceptibilities of planktonic versus biofilm populations, because the cell densities in the two populations were similar and because the concentration required to inhibit bacterial metabolism rather than to eradicate the entire bacterial population was measured.
