Estudou-se a influência da consistência do meio de cultura sobre a organogênese de ápices meristemáticos de batata nas etapas de isolamento e multiplicação in vitro, das cultivares Baronesa, Eliza e Pérola. Para o cultivo utilizaram-se tubos de ensaio (20 x 150 mm) contendo 5 ...

O uso de estacas de batata a partir de plantas multiplicadas in vitro pode transformar-se em técnica bastante eficiente para melhorar a taxa de multiplicação de material com alta qualidade fitossanitária. O trabalho objetivou estabelecer um protocolo para a produção de mudas pré-básicas...

This study investigates the development and characterization of bioactive films incorporating silver nanoparticles (AgNPs) into biocompatible polymers, namely alginate and chitosan, fabricated using two methods, spin-coating and drop-casting, and aiming to enhance their antimicrobial properties. Dynamic light s...

Liposomes are promising carriers for enhancing antibiotic delivery, but their stability under various stress conditions is crucial for clinical applicability. Methods: This study aimed to evaluate the physicochemical and antimicrobial stability of streptomycin-loaded liposomes subjected to mechanical (bath ...

Bemisia tabaci (Genn.) was considered a secondary pest in Brazil until 1990, despite being an efficient geminivirus vector in beans and soybean. In 1991, a new biotype, known as B. tabaci B biotype (=B. argentifolii) was detected attacking weed plants and causing phytotoxic problem...

Kraft paper, commonly known as brown paper, has been widely used in the preservation of various food products and is increasingly explored in the development of active packaging materials with antimicrobial functionality by incorporating metal nanoparticles. This study aimed to comparatively ...

Ceratocystis fimbriata was found sporulating in gray to black discolored areas on edible corms of Colocasia esculenta found in supermarkets in the states of São Paulo, Rio de Janeiro, Bahia, Rondônia and the Distrito Federal. In most cases the corms were grown in the state...

In the past two decades, synthetic biology has emerged as a transformative field at the frontier of innovation, evolving from fundamental technological advancements to the commercialization of innovative products. The field is providing breakthrough innovations to address societal challenges and ...

This Open Letter highlights peatlands as critical yet overlooked ecosystems in Brazil's climate and biodiversity policies. By translating scientific evidence into clear, actionable priorities for policymakers, it supports more accurate climate reporting, effective mitigation strategies, and improved land-us...
