The present investigation aimed at large-scale genome wide identification and characterization of glutathione S-transferases (GST) gene family in sugar beet (Beta vulgaris subsp. vulgaris). A total of 35 GST genes were identified in sugar beet that were divided into 10 classes of which tau (19) and phi (4) were the most abundant. Sub-cellular localization analysis revealed that most of the identified beet GST proteins were localized in the cytoplasm. Gene duplication analysis revealed that purifying type selection and tandem duplication were majorly responsible for expansion of the gene family. Multiple sequence alignment showed that serine and cysteine catalytic residues were highly conserved in beet GSTs. The present study identified 26 cis-acting regulatory elements which were responsible for responses against different types of stresses and plant development. The evolutionary relationship of beet GST proteins showed that the tau and phi class GSTs were closely associated with those of other plants. This comprehensive study of GST gene family in sugar beet provides firm base for functional analysis of beet GST genes at molecular level along with potential applications in genetic improvement of the crop.

Thailand's sugarcane industry plays a key role in the nation's economy and agricultural sector, facing significant challenges including climate change, market fluctuations, and environmental concerns. To overcome these challenges, the industry is innovating through the development of drought-resistant sugarcane varieties and the adoption of precision agriculture techniques, aimed at enhancing yield and sustainability. Additionally, the sector is diversifying its output by venturing into the production of biofuels, bioplastics, and other bio-based materials, as well as high-value-added products for cosmetic and medical purposes. This strategic diversification is designed to reduce reliance on traditional sugar exports and foster new economic opportunities. Furthermore, the implementation of the Bio-Circular-Green (BCG) model policy is transforming the industry. This model facilitates the conversion of sugarcane into various valuable by-products, promoting resource efficiency and waste reduction. Emphasizing environmental stewardship, economic viability, and social responsibility, the BCG model ensures that the sugarcane industry remains a key to sustainable success of Thailand’s sustainable development strategy.

Effective supply chain management is crucial to ensure the smooth flow of sugarcane from farms to sugar mills and ultimately to consumers. This review paper explores key challenges of sugarcane supply chain management in the field of seasonal variability, quality control, procurement and pricing, logistics and transportation, sustainability and environmental concerns, supply chain coordination, and price fluctuations faced by the sugarcane supply chain management, highlighting the complexities and obstacles that impact its efficiency and sustainability. The analysis encompasses comprehensive understanding of the issues related to procurement, transportation, processing, and distribution within the sugarcane supply chain management. Additionally, potential solutions and strategic interventions to address these challenges are described to improve and enhance the performance, efficiency, sustainability, profitability, and overall sugarcane supply chain management.

The green synthesis of silver nanoparticles (AgNPs) and their applications have gathered great attention as these nanoparticles can be used effectively in targeting microorganisms due to their antimicrobial properties. In this study, the reducing and capping potential of polyphenols extracted from energy cane bagasse was investigated in the green synthesis of AgNPs without the external addition of reducing agents. The reddish color formation and peak appearance at 430 nm were indications of the successful synthesis of the AgNPs. The synthesized nanoparticles and reducing biomolecules were further characterized by microscopy (SEM, TEM) and spectroscopy (FTIR-ATR, EDS, XRD) techniques indicating nanoparticles of spherical shape, with particle sizes averaging ~ 15 nm and surface charge of −24.8 mV. The antimicrobial activity of the synthesized nanoparticles was evaluated against several microbial species, Listeria monocytogenes ATCC 19115, Staphylococcus aureus ATCC 12600, Salmonella enterica ATCC 13312, Pseudomonas syringae ATCC BAA 871, Escherichia coli ATCC 35218, and two strains isolated from sugarcane crusher juice, Leuconostoc mesenteroides (A17) and Leuconostoc pseudomesenteroides (A25). The synthesized nanoparticles showed biocidal activity against the bacteria which was further confirmed by microscopy techniques. The cell and nanoparticles are interacting with the cell surface of microorganisms, penetrating the cell, and causing the disruption of intracellular organelles. These nanoparticles also prevented the growth of microbial biofilms. A biofilm is a complex and functional community of microbes encased in a primarily polysaccharide matrix, which acts as a barrier to protect microbes against most antimicrobials.

The need for more efficient ethanol production methods from sugarcane-based substrates has necessitated the study of (very) high-gravity fermentation strategies. High gravity (HG) and very high gravity (VHG) fermentation are fermentation processes that involve fermenting substrates with significantly higher concentrations of sugars or solids than traditional fermentation methods, typically leading to higher ethanol yields and process efficiencies. This review provides a comprehensive overview of recent advancements, challenges, and future prospects in HG and VHG fermentation for ethanol production from sugarcane-based substrates. It was observed that sugarcane juice, molasses, and bagasse have been used for the production of ethanol. It was also observed from various studies that the use of tailored yeast strains, coupled with optimized process conditions such as fermentation temperature, residence time, pH, substrate concentration, aeration, additional supplements, and the presence of inhibitors, has yielded remarkable improvements in the fermentation efficiency of sugarcane-based substrates and ethanol yields. Additionally, challenges in implementing HG and VHG fermentation of sugarcane-based substrates, as well as recommendations for further research and development, are presented. This study’s significance cannot be overstated, as it has the potential to advance biofuel technology by optimizing ethanol yields from sugarcane, thereby promoting sustainable energy solutions.

Bioethanol, as a sustainable alternative to the fossil fuels is gaining more attention now a times. To address the growing energy demands and environmental problems, this sustainable practice plays a vital role. Bioethanol is a more reliable source, produced by lignocellulosic biomass which is abundantly available. This review article focuses on the valorization of the LCB to produce Bioethanol by understanding various pathways that can be utilized to produce bioethanol. Many pretreatment methods play an effective role in converting biomass into fermentable sugars that have an implicit effect on bioethanol production. This review highlights the challenges and the environmental problems that need to be overcome to achieve cost production and the meeting energy demands. This greener solution toward mitigating energy resource depletion will lead to a greener and more eco-friendly future for coming generation. This review also addresses the present technological advancements that prove the bioethanol as a most potential source for the eco-friendly energy future.

The challenge of sustainability has emerged as a primary concern across numerous industries globally including the sugar sector. The importance of adopting sustainable practices is increasingly acknowledged on a global scale. The sugar industry occupies a unique position and has the potential to make significant contributions to various vital Sustainable Development Goals. Over the years, the sugar industry has supported and advanced these goals through diverse strategies, including the utilization of sugarcane byproducts for alternative purposes such as ethanol production, cogeneration of energy from cane bagasse, and the development of bio-based products. In this endeavor, ASEAN countries are united in harnessing the versatility of sugarcane bio-products for a greener and more resilient future. Sugarcane offers a sustainable alternative to traditional fossil-based byproducts through the production of biofuels, biochemicals, and bioplastics. This transition to a bio-based economy not only conserves limited resources by reducing usage but also diminishes the carbon footprint. By embracing and preserving these renewable resources, the various initiatives and efforts undertaken by ASEAN sugar industries can promote economic growth, environmental stewardship, and social well-being, thereby paving the way for a more sustainable and resilient future.

Summer sugar beet growing regions such as the Central Anatolia Region of Türkiye face a shortage of irrigation water. For this reason, we tested autumn sowing sugar beets without irrigation in the Aegean Coastal Zone, where sugar beet cultivation is not practiced. The two-year study was conducted in a split-plot experimental design with four replications. Terranova, Aranka and Dionetta cultivars were sown on 1 December 2020 and 30 November 2021. Ridge sowing was implemented to minimize the possibility of bolting and to prevent them from being affected by excessive December, January and February rainfall. There was no frost-induced seedling loss during the winter growing season and no bolting in the following spring in both years. Growing degree days (GDD) from emerging to harvest (1956 vs. 1497) were higher in the yielding year. Higher solar radiation in the first year (757.30 kWh m⁻² vs. 673.80 kWh m⁻²) during the vegetation period was positively associated with GDD and yield. Ridge sowing and Terranova cultivar performed superbly in terms of root yield, sugar content, SPAD value and Fv/Fm. It was concluded that autumn-sown sugar beet can be grown in the Aegean Coastal Zone as an alternative to the Central Anatolia Region without irrigation with the ridge sowing method.
