Root Order Dependent Changes in Fine‐Root Substrate and Soil Environment Regulate Soil Organic Nitrogen Fractions Under Acid Rain and Nitrogen Deposition

Land Degradation &Development, EarlyView.
ABSTRACT Acid rain and nitrogen deposition are important environmental stressors affecting soil nitrogen cycling in subtropical forests, whereas fine‐root decomposition represents a major pathway for soil organic nitrogen (SON) input and transformation.

Ecosystem retrogression enhances cross‐domain microbial stability and increases the genetic potential for nutrient cycling

mLife, EarlyView.
Abstract Ecosystem retrogression drives nutrient depletion, reduced productivity, and profound reorganization of soil microbial communities. Using amplicon sequencing and genome‐resolved metagenomics, we examined how cross‐domain microbial networks and functional gene potential respond to long‐term phosphorus and nitrogen limitation along the well ...

Chemical Modification of Laccase from Aspergillus oryzae and its Application in OCC Pulp

BioResources, 2016
Laccase activity and stability were improved and modified through the interaction between laccase amino acid residues (e.g., amino groups (-NH2) and carboxyl groups (-COOH)) and the chemical reagents thiourea dioxide (TDO) and L-phenylalanine methyl ...

Production of a novel laccase from Ceratorhiza hydrophila and assessing its potential in natural dye fixation and cytotoxicity against tumor cells

Journal of Genetic Engineering and Biotechnology, 2023
Background Flavonoid natural dyes have gained attention because they are nontoxic and eco-friendly. However, they do not work effectively with artificial fibers and require the use of mordants, which are considered as hazardous chemicals.

Photocatalytic and Biotechnological Strategies for Remediation of Persistent Organic Pollutants: Mechanisms, Toxicity, and Antimicrobial Perspectives

Environmental Toxicology, EarlyView.
ABSTRACT Persistent organic pollutants (POPs) pose significant ecological and human health risks due to their persistence, bioaccumulation, toxicity, and global distribution. Conventional remediation methods are often inadequate for achieving complete mineralization, demonstrating the need for advanced and substantial approaches.

Laccase: Properties and applications

BioResources, 2009
Laccases (benzenediol:oxygen oxidoreductase, EC 1.10.3.2) are multi-copper oxidases that are widely distributed among plants, insects, and fungi. They have been described in different genera of ascomycetes, some deuteromycetes, and mainly in basidiomycetes.

Comparative Analysis of Stress Adaptation in the Yeast Microbiome of Cactus

Yeast, EarlyView.
Yeasts and related fungi isolated from cacti or nearby non‐cactus plants were characterized phenotypically and genomically, revealing differences that hint at modes of adaptation to the cactus host. ABSTRACT Together with other fungi, yeasts make up a significant component of the plant microbiome. As the planet warms, cacti expand their range.

Creating Designer Laccases

Chemistry & Biology, 2010
High redox potential laccases from white-rot fungi are recalcitrant to engineering. Maté et al. (2010) employed directed evolution to improve the activity and expression level of the fungal laccase from basidiomycete PM1, followed by rational design to restore thermostability lost during evolution, resulting in a highly active and stable enzyme.

β-Carotene from Yeasts Enhances Laccase Production of Pleurotus eryngii var. ferulae in Co-culture

Frontiers in Microbiology, 2017
Laccase is widely used in several industrial applications and co-culture is a common method for enhancing laccase production in submerged fermentation. In this study, the co-culture of four yeasts with Pleurotus eryngii var.

Transcriptomic and proteomic signatures underlying nymphal adaptation and foam production in the forage pest Mahanarva spectabilis

Insect Molecular Biology, EarlyView.
RNA‐seq and Batelli gland proteomics of fifth‐instar Mahanarva spectabilis nymphs reveal transcripts and proteins associated with xylem feeding, foam production and environmental interaction. Functional annotation identified genes involved in osmoregulation, detoxification, chemosensation and stress responses, while proteomic analysis confirmed ...
