Título: Conserved transcriptional responses to salt and water stress in oil palm (Elaeis guineensis Jacq.) leaf tissues. Autoria: SALGADO, F. F.; SILVA, T. L. C. da; LEAO, A. P.; TOGAWA, R. C.; SOUSA, C. A. F. de; GRYNBERG, P.; SOUZA JUNIOR, M. T. Conteúdo: Abiotic stresses negatively impact oil palm (Elaeis guineensis Jacq.) cultivation. Transcription factors (TFs) are essential proteins regulating gene expression in plants. While numerous TF gene families are implicated in plant responses to abiotic stress, their specific roles in oil palm’s drought and salinity responses remain largely unexplored. This study aimed to get insights into the TFs’ involvement in the oil palm’s response to these stresses.

Título: Diversification of oil-bearing biomass sources for decarbonization and sustainability. Autoria: LOPES, M. A.; LAVIOLA, B. G.; FAVARO, S. P. Conteúdo: Abstract: The objective of this review was to analyze the diversification of oil-bearing biomass sources as a strategic pathway to support decarbonization and sustainability, with emphasis on bioenergy in Brazil. The review identifies opportunities, challenges, and conditions to expand the use of diverse oily crops. The work is based on scientific publications, technical reports, and institutional documents addressing biomass and bioenergy production. It highlights the potential of oily crops, such as macaúba and tropicalized canola, to expand biomass supply for biofuels and bioproducts. In addition, it examines integrated agricultural systems that combine biomass production with environmental restoration. Such an approach shows that diversifying oil-bearing crops can reduce pressure on traditional feedstocks such as soybean and oil palm, which face sustainability concerns abroad and can be highly affected by climate change. Technological, regulatory, and financial challenges that must be overcome for large-scale adoption of new crops were identified. The review also presents lessons from past failures, showing that success depends on long-term research, breeding, and risk management. Diversifying oil-bearing biomass sources strengthens climate mitigation, rural development, and bioeconomy strategies, positioning Brazil as a leader in the production of sustainable biomass.

Título: Xylonic acid production from sugarcane bagasse hydrolysate using an engineered Komagataella phaffii strain. Autoria: ALMEIDA, I. C. DE; ALMEIDA, J. R. M. de; MACHADO, F.; GONCALVES, S. B. Conteúdo: Xylonic acid is an oxidized derivative of xylose that is used by the food, pharmaceutical, and chemical industries. It can be produced either microbially or chemically. Biological production is advantageous because of its safety, eco-friendliness, and mild process conditions. This study used a recombinant Komagataella phaffii strain modified to produce xylonic acid from xylose. Glucose and glycerol were evaluated as co-substrates in batch and fed-batch fermentations in flasks and in bioreactor cultures. Glycerol was an effective carbon source for improving growth and product production.

Título: Targeted redesign and optimization of culture media for ethylene glycol biosynthesis in Komagataella phaffii. Autoria: PACHECO, T. F.; ALMEIDA, J. R. M. de Conteúdo: Tailoring culture media and supplementation strategies to the specific requirements of a target product is essential for enhancing microbial production efficiency. This work addresses an unexplored aspect of K. phaffii cultivation: optimizing culture media for metabolite production from xylose, diverging from the conventional focus on recombinant protein expression and the use of glycerol or methanol as primary substrates. Ethylene glycol biosynthesis in an engineered K. phaffii strain was improved by evaluating media and nutrient supplementation. Among the seven evaluated formulations, FM22 and d’Anjou were the most effective, with inositol and thiamine dichloride playing key roles in enhancing production. Salt concentrations in both media were optimized using Central Composite Design (CCD), reducing complexity while increasing yields. Ethylene glycol production increased by 54% in FM22 and 21% in d’Anjou, accompanied by a threefold and 26% reduction in the total salt content, respectively. The vitamin solution was streamlined from seven to two components, each at half the standard concentration. Trace element solutions were reduced to 25% of the original volume without compromising productivity. These findings underscore the dual benefit of culture medium optimization: improved ethylene glycol yields and simplified formulations, establishing a foundation for the development of more efficient and cost-effective bioprocesses using K. phaffii.
