Abstract:
... Maggot therapy (MT) is the clinical application of living fly larvae for the treatment of non‐healing wounds and wounds that require debridement. This systematized and expanded literature review is the first study to investigate MT through the conceptual and disciplinary framework of supply chain management. The review of 491 selected academic papers was expanded to include the grey literature and ...

Abstract:
... Oak barrels form an integral part of wine production, especially that of high-quality wines where they are implemented as fermentation and aging vessels. Insufficient cleaning and sanitization of barrels can result in microbial spoilage which may have a detrimental impact on wine quality. To date, no review has been published on the various sanitization methods for wine barrels. The objective of t ...

Abstract:
... Food processing can lead to a reduction of contaminants, such as mycotoxins. However, for food processing operations where thermal energy is employed, it is often not clear whether a reduction of mycotoxins also results in a mitigation of the toxicological impact. This is often due to the reason that the formed degradation products are not characterized and data on their toxicity is scarce. From t ...

Abstract:
... Bio-based levulinic acid is easily ring-closed to α-angelica lactone (α-AL). α-AL can be isomerized to the conjugated β-AL under the influence of base, but since this is an equilibrium mixture it is very hard to devise a scalable process that would give pure β-AL. This problem was circumvented by distilling the equilibrium mixture to obtain a 90 : 10 mixture of β- and α-AL in 88% yield. This mixtu ...

The internal transcribed spacer (ITS) region of the ribosomal DNA (rDNA) has been established (and is generally accepted) as a primary “universal” genetic barcode for fungi for many years, but the actual value for taxonomy has been heavily disputed among mycologists. Recently, twelve draft genome sequences, mainly derived from type species of the family Hypoxylaceae (Xylariales, Ascomycota) and th ...
