A 17-year-old has come up with an innovative solution for removing toxic dyes from wastewater that are the leading detrimental chemicals found in the textile industry. ....
The ability of oxidative enzyme-producing micro-organisms to efficiently valorize organic pollutants is critical in this context. Yeasts are promising enzyme producers with potential applications in waste management, while lipid accumulation offers significant bioenergy production opportunities. The aim of this study was to explore manganese peroxidase-producing oleaginous yeasts inhabiting the guts of wood-feeding termites for azo dye decolorization, tolerating lignocellulose degradation inhibitors, and biodiesel production. Out of 38 yeast isolates screened from wood-feeding termite gut symbionts, nine isolates exhibited high levels of extracellular manganese peroxidase (MnP) activity ranged between 23 and 27 U/mL after 5 days of incubation in an optimal substrate. Of these MnP-producing yeasts, four strains had lipid accumulation greater than 20% (oleaginous nature), with Meyerozyma caribbica SSA1654 having the highest lipid content (47.25%, w/w). In terms of tolerance to lignocellu ....
Yarrowia sp., and Vanrija humicola. However, to the best of our knowledge, there are some novel yeast species isolated from R. chinenesis and Starmera dryadoides, Candida gotoi, and Hamamotoa lignophila. Recently, there has been an increase in the number of studies on the gut symbionts of xylophagous insects like termites, especially termite digestome, both termites and their gut symbionts, which have many potential bioenergy applications that need careful consideration [28, 29]. In contrast to previous studies on lignin breakdown, which gave no convincing evidence of microbial degradation of lignin in the termite intestinal tract [30], recent studies reported that the paunch of termites harbors a significant number of lignin-degrading yeasts [31,32,33,34]. Schäfer et al. [35] reported that yeasts were ranged between 10 ....
