O PAPEL DAS BACTÉRIAS PRODUTORAS DE ÁCIDO INDOLACÉTICO (AIA) NO ENRAIZAMENTO E CRESCIMENTO VEGETAL
(Instituto Federal Goiano, 2026-03-27) Silva, Danilo Ferreira; Oliveira, Patrícia Rasteiro Ordiale; http://lattes.cnpq.br/2130602862308818
Indoleacetic acid (IAA) is the main natural auxin involved in regulating plant growth-promoting bacteria. In recent years, the scientific community has focused its attention on the use of plant growth-promoting bacteria (PGPB), especially those capable of producing IAA, as a sustainable alternative to stimulate germination, rooting, and development in different plant species. This review brings together evidence from studies demonstrating the effectiveness of these bacteria in various agricultural crops and plant species, including vegetables and plants propagated by cuttings or micropropagation. Among the microorganisms most cited in the literature are species of the genera Rhizobium, Bacillus, Pseudomonas, Enterobacter, Pantoea, Burkholderia, and Azospirillum, recognized for their ability to synthesize IAA and promote plant growth. The results analyzed indicate that, when well selected, these bacteria have the potential to improve root development, promote nutrient absorption, and contribute to increased plant vigor, potentially reducing the use of synthetic inputs partially or totally. However, some studies indicate that excessive concentrations of IAA can cause negative physiological effects, highlighting the importance of proper management of these microorganisms. It is concluded that the rational use of AIA-producing bacteria represents a promising strategy for strengthening

Digital inclusion presents a central challenge for achieving equitable education in Professional and Technological Education (PTE). This study investigates the economic, geographic, and social barriers that hinder access to digital technologies and analyzes their impacts on the technical training of students in different contexts. Using critical frameworks such as Freire (1996, 2005), who advocates for emancipatory education, and Saviani (2020), who discusses the school's role in overcoming social inequalities. The work also dialogues with Tapscott (2008) on the digital generation and with Bourdieu and Passeron (1970) on the reproduction of inequalities in the educational field. The methodology adopts a mixed approach, combining a literature review, analysis of secondary data (IBGE, Cetic.br, and INEP), and the planned collection of primary data in technical schools. Preliminary results indicate that digital exclusion compromises the use of innovative methodologies, the development of digital competencies, and student retention, especially in rural and peripheral regions (Oliveira & Scopel, 2024; Marques, Vieira & Pontel, 2020). Thus, it is evident that inequality in access to technologies perpetuates a cycle of social and professional exclusion, reinforcing the urgency of public policies that promote digital inclusion as a basic educational right and a condition for comprehensive human development.

This work aimed to analyze vegetable production and its socioeconomic and nutritional importance for families in situations of social vulnerability in the municipality of Pontalina-GO, through the solidarity garden extension project. The project has been developed since 2021 in partnership between the Instituto Federal Goiano – Campus Morrinhos, public authorities and local institutions, aiming to promote food security, academic training for students and strengthening vegetable farming. The methodology was based on the diversified production of vegetables, the registration of families in situations of social vulnerability and the distribution of the food produced. In the period from 2021 to 2025, approximately 400 families were served, in addition to social institutions in the municipality. There was a high production capacity and diversity of crops, with emphasis on cabbage, parsley, jilo and pumpkin. The results indicate that the project contributes to improving the quality of life of benefiting families, expanding access to healthy foods, in addition to promoting technical training for students and rural producers. It is concluded that the initiative has social, educational and productive relevance, configuring itself as an efficient strategy for promoting food security, social inclusion and sustainable development.

O USO DE MICRORGANISMOS NA MITIGAÇÃO DE MICOTOXINAS
(Instituto Federal Goiano, 2026-03-23) Pires, Marcela Monize Oliveira de Faria; Paz Filho, Erasmo Ribeiro da; http://lattes.cnpq.br/9776944451005766; Vaz, Aline Brito; http://lattes.cnpq.br/1228585008963072; Souza, Tenille Ribeiro de; http://lattes.cnpq.br/4144514561620320
Mycotoxins are secondary metabolites produced by filamentous fungi such as Aspergillus, Fusarium, and Penicillium that contaminate grains, cereals, and other plant-based foods, posing serious risks to human and animal health as well as significant economic losses. Given the limitations of conventional physical and chemical methods for mycotoxin control, the use of microorganisms has emerged as a promising and sustainable biotechnological alternative. In this context, the general objective of this study was to analyze the use of microorganisms in combating mycotoxins, emphasizing their mechanisms of action, effectiveness, and potential application within the food and feed production chain. The methodology consisted of a descriptive and analytical literature review based on the selection of scientific articles, books, and technical documents published in recognized databases such as Scopus, PubMed, and SciELO. Studies addressing the use of bacteria, yeasts, and fungi with the capacity for adsorption, biotransformation, or degradation of mycotoxins were included, with priority given to recent publications. Data analysis was conducted qualitatively in order to identify patterns, recurring findings, and gaps in the scientific knowledge on the subject. The main results indicate that several microorganisms exhibit high efficiency in mycotoxin control. Lactic acid bacteria, such as Lactobacillus and Bifidobacterium, demonstrate the ability to adsorb mycotoxins on their cell walls, thereby reducing their bioavailability. Yeasts, particularly Saccharomyces cerevisiae, stand out for their physical binding to toxins and their practical application as feed additives. In addition, certain microorganisms possess specific enzymes capable of degrading mycotoxins into less toxic compounds, as observed in bacterial and fungal species with biotransformation activity. The analyzed studies report significant reductions in toxicity, improved food safety, and lower environmental impact when compared to traditional methods. It is concluded that the use of microorganisms in combating mycotoxins represents an effective, safe, and environmentally sustainable strategy with great potential for industrial application. Despite these advances, further studies are required to standardize microbial strains, evaluate their stability in different food matrices, and validate their effectiveness on an industrial scale. Therefore, microbial biotechnology represents a strategic field for the development of innovative solutions in mycotoxin control and the promotion of food safety. Keyword: Mycotoxins. Biocontrol.

This study analyzes practices and strategies aimed at retaining students in the the National Program for the Integration of Professional Education with Basic Education in the Youth and Adult Education modality (Proeja), focusing on the Technical Course in Administration at the Federal Institute of Brasília, Gama campus, from a comparative perspective with institutions of the Federal Network of Professional, Scientific and Technological Education. The research is based on the problem of high dropout rates observed in this educational modality and seeks to understand how institutional, pedagogical, and social factors influence the academic trajectory of working students. The objective is to analyze the relationship between institutional policies, curriculum organization, and pedagogical practices with indicators of student retention. Methodologically, this is a qualitative study with an exploratory and analytical approach, grounded in the historical-dialectical materialist perspective, complemented by quantitative data obtained from the Nilo Peçanha Platform for the period between 2020 and 2024. Pedagogical Course Projects (PPCs) from institutions in the Midwest region of Brazil were also analyzed, considering four main theoretical axes: integrated curriculum, active learning methodologies, recognition of prior knowledge, and psycho-pedagogical support. The results indicate that dropout in the Proeja Administration program presents a structural character within the Federal Network, revealing a mismatch between the pedagogical guidelines described in the PPCs and their effective implementation in institutional practice. The study concludes that student retention depends on the articulation between pedagogical policies, systematic institutional monitoring, and recognition of the concrete living conditions of working students, contributing to the consolidation of Proeja as a public policy aimed at integral human development and educational inclusion.
