“…Based on the results obtained about strain identification, the degradation of dyes reported in this work on agar plates (Figure 1) are coincident with previous reports related to the Phlebia genus [31][32][33]. P. floridensis strains are able to degrade azo-and triphenylmethane dyes as it observed in Figure 1c.…”

Phlebia genus is a relevant group of fungi with a crucial role in numerous ecosystems. In tropical and subtropical areas this genus allows the efficient degradation of lignin and carbon recovery; however, the majority of these fungal species remain undiscovered. The main purpose of this work was to determine the enzymatic activity of extracellular proteins of a novel Phlebia floridensis strain isolated in Yucatan Peninsula, Mexico. The results that are reported here demonstrate that the soluble protein extract of P. floridensis can degrade a broad spectrum of recalcitrant compounds. This induced protein extract is able to modify not only phenolic and nonphenolic compounds, but also anthroquinone dyes, even without the addition of exogenous hydrogen peroxide. Using liquid chromatography–mass spectrometry (LC‐MS), we were able to identify a novel chloroperoxidase in enzymatic extract. As far as we know, this is the first report about the presence of this type of enzyme in the Phlebia genus.

Lignocellulosic biomass, such as plant residues and agricultural waste, holds immense potential as a renewable resource for the production of biofuels, chemicals, and animal feed. However, the efficient degradation of lignocellulose into fermentable sugars remains a significant challenge. Recent research has highlighted the critical role of microbial diversity in lignocellulosic biomass degradation, offering new insights from a biotechnological perspective. The comprehension and utilization of microbial diversity are crucial for developing efficient biotechnological strategies for lignocellulosic biomass degradation. By uncovering the intricate relationships between microbial communities and their enzymatic machinery, researchers can optimize degradation processes, enhance biofuel production, and contribute to a more sustainable bio‐based economy. Microorganisms, including bacteria, fungi, and archaea, possess diverse enzymatic capabilities, allowing them to secrete a plethora of lignocellulolytic enzymes. Microbial organisms inhabiting extreme environments, such as the rumen, hot and cold springs, deep sea trenches, and acidic and alkaline pH environments, exhibit significant potential in generating enzymes, including hemicellulolytic and lignocellulolytic enzymes, which possess superior biochemical properties essential for industrial bioconversion applications. This review explores the ability of lignocellulosic enzymes from microbial sources to efficiently break down the lignocellulosic biomass and their potential applications in industrial biotechnology.
