In recent years, there has been an increase in research devoted to the advancement of cellulose and nanocellulose-based materials, which are advantageous due to their renewable nature, strength, rigidity, and environmental friendliness. This exploration complies with the fundamental tenets of environmental stewardship and sustainability. An area of industrial biotechnology where cellulosic agricultural residues have the potential to be economically utilized is through the conversion of such residues; sugarcane bagasse is currently leading this charge. SCB, a plentiful fibrous byproduct produced during the sugarcane industry's operations, has historically been utilized in various sectors, including producing paper, animal feed, enzymes, biofuel conversion, and biomedical applications. Significantly, SCB comprises a considerable amount of cellulose, approximately 40 % to 50 %, rendering it a valuable source of cellulose fibre for fabricating cellulose nanocrystals. This review sheds light on the significant advances in surface modification techniques, encompassing physical, chemical, and biological treatments, that enhance sugarcane bagasse fibres' adsorption capacity and selectivity. Furthermore, the paper investigates the specific advancements related to the augmentation of sugarcane bagasse fibres' efficacy in adsorbing a wide range of pollutants. These pollutants span a spectrum that includes heavy metals, dyes, organic pollutants, and emerging contaminants. The discussion provides a comprehensive overview of the targeted removal processes facilitated by applying modified fibres. The unique structural and chemical properties inherent in sugarcane bagasse fibres and their widespread availability position them as highly suitable adsorbents for various pollutants. This convergence of attributes underscores the potential of sugarcane bagasse fibres in addressing environmental challenges and promoting sustainable solutions across multiple industries.

Biochar reduces containerized pepper blight caused by Phytophthora Capsici.
Sci Rep

Department of Horticulture and Landscape Architecture, Colorado State University, Fort Collins, CO, 80526, USA.
Phytophthora blight caused by Phytophthora capsici is a serious disease affecting a wide range of plants. Biochar as a soil amendment could partially replace peat moss and has the potential to suppress plant diseases, but its effects on controlling phytophthora blight of container-grown peppers have less been explored, especially in combination of biological control using Trichoderma. In vitro (petri dish) and in vivo (greenhouse) studies were conducted to test sugarcane bagasse biochar (SBB) and mixed hardwood biochar (HB) controlling effects on pepper phytophthora blight disease with and without Trichoderma.

The present study reports the ability of a fungal isolate DY1, obtained from rotten wood, to degrade alkali lignin (AL) and lignocelluloses in an efficient manner. The efficiency of degradation was monitored by measuring the percentage of decolorization and utilizing GC-MS for identifying degradation products at different time intervals (10, 20, 30, and 40 days). The optimal degradation of alkali lignin (AL) was achieved at 0.

The complex structure of the plant cell wall makes it difficult to use the biomass produced by biosynthesis. For this reason, the search for new strains of microorganisms capable of efficiently degrading fiber is a topic of interest. For these reasons, the present study aimed to evaluate both the microbiological and enzymatic characteristics of the fungus L7strain.

Article Synopsis
- Ozone is effective in extracting lignocellulosic fibers due to its selectivity for lignin, but the mechanism of lignin degradation during this process is not well understood.
- Researchers examined the structural changes in milled wood lignin from scutched flax tow before and after ozone treatment using various analytical techniques.
- The study found that ozone treatment damaged specific lignin linkages and converted S-type lignin units into G-type units, offering important insights into the delignification process in lignocellulosic fiber extraction.

β-glucosidases (BGLs) are key enzymes in the depolymerization of cellulosic biomass, catalyzing the conversion of cello-oligosaccharides into glucose. This conversion is pivotal for enhancing the production of second-generation ethanol or other value-added products in biorefineries. However, the process is often cost-prohibitive due to the high enzyme loadings required.
