Enhancing chain-elongating microbiomes: Sequential fungi-bacteria cooperation for efficient food waste upgrading using endogenous electron donors
PublikacjaThe upgrading of organic waste such as food waste (FW) into medium-chain carboxylates (MCC) is within a bio-based circular economy concept. An efficient chain elongation (CE) microbiome is difficult to obtain, which normally requires long-term acclimatization and an exogenous supplement of electron donor (ED, especially ethanol). In this study, the CE microbiome was rapidly shaped within 18 days and an efficient endogenous ethanol-based...

Why do Open Government Data initiatives fail in developing countries? A root cause analysis of the most prevalent barriers and problems
PublikacjaOpen government data (OGD) include the provision of government data, which have so far been reserved for the provision of public utilities and services, wherein different stakeholders may create value out of the same source. Recently, OGD initiatives around the world have dampened or were found to be inadequate for one or other reasons. The present study seeks to underline the root causes behind these inadequate or stalled initiatives...

Bodybuilders and high-level meat consumers’ behavior towards rabbit, beef, chicken, turkey, and lamb meat: A comparative review
PublikacjaIn bodybuilders’ diets, protein plays a crucial role in supporting muscle growth and repairing damaged muscle tissue. These individuals meet their protein needs by combining dietary sources with supplements. Animal-based proteins are often preferred over plant-based proteins because they are believed to better support muscle protein synthesis. This review explores the meat consumption patterns of bodybuilders and high-level meat...

Oznaczanie pozostałości pestycydów w próbkach żywności w wykorzystaniem metodyki QuEChERS = QuEChERS approach for the determination of pesticide residues in food matrixes
PublikacjaBez wątpienia, wartym uwagi podejściem do problemu oznaczania pestycydów, ze względu na różnorodność tej grupy związków, jest zastosowanie metodyk oznaczania pozostałości (multi-residue methods - MRMs). Niestety, w literaturze naukowej można znaleźć stosunkowo niewiele informacji na temat takiego podejścia do oznaczania pozostałości pestycydów w próbkach żywności. Stąd próba przybliżenia czytelnikom kilku najistotniejszych, zdaniem...
