Researchers develop symbiotic fermented coconut-based drink

Open coconut on a white surface.

A symbiotic fermented coconut-based drink, developed by researchers from UFRRJ in collaboration with PUCMM and Embrapa, demonstrates a microbiological stability of 28 days under refrigeration, highlighting probiotic and antioxidant benefits. The product is a promising plant-based alternative in the production of probiotic beverages, with the potential to meet the growing demands of vegetarian, vegan, and food-allergic consumers.

Study suggests that milk ring test can be done on samples with Bronopol

Brucellosis is a disease caused by bacteria and can be transmitted to humans through direct or indirect contact with farm animals or by contact with companion animals. The milk ring test (MRT) is one of the ways used to identify the disease at the dairy herd level. Analyses indicate that the MRT can be used on milk samples with a preservative (Bronopol®).

Analysis reveals reduction of pesticides in CEASA/SP strawberries

Several strawberries scattered and overlapping.

Strawberries are popularly known as a crop with pesticide residues. However, after analyzing residues found in 62 samples of strawberries produced in the state of Rio Grande do Sul and sold at CEASA/RS between 2018 and 2019, a reduction in the percentage of strawberry samples with non-conformities regarding the presence of residues was observed.

Dogs are quite popular domestic animals around the world, yet their bite is a major public health problem. From the analysis of data on dog bites in Naples, serious and profound inconsistencies were found, revealing structural and significant weaknesses in the current data collection system. Read More →

Planting trees on degraded pastures might improve the recovery of the soil

Photo of a man in a laboratory. He is standing in front of a table with equipment and a grid with several tubes. He holds one of the tubes with a tool and uses a tool inside the container.

The conversion of degraded pastures to forest legumes and soil depth promoted changes in the chemical composition of carbon. Through chemical carbon fractionation it is possible to detect in a fast and promising way soil chemical changes caused by land use and management techniques. Read More →

Water use in coconut crop can be more efficient during drought with deficit irrigation

Well-lit photo of a coconut tree with at least 10 coconuts on the tree and very wide leaves. On the ground, grass, soil, and two piles of coconuts (about 30 coconuts).

Sustained deficit irrigation can increase the efficiency of water use in dwarf coconut irrigation, but significantly reduces its productivity. The use of this technique is only economically justified in situations of restricted water supply for irrigation, as occurs during droughts in the Brazilian Northeast. Read More →

Mares vaccinated at the end of pregnancy have a higher number of antibodies against equine pyroplasmosis

Photo: adult horse and baby horse walking in a pasture.

Mares vaccinated in the final third of gestation showed higher specific total vaccine antibodies for immunization against Theileria equi and Streptococcus equi subspecies equi, and the antibodies were also transferred to their foals, which may contribute to a vaccination schedule based on foal age that optimizes control against such diseases.

Evaluation of genetic resistance to brusone in wheat grown in Brazil

Photo: branches of wheat.

In evaluating the resistance of wheat genotypes to brusone, the updated characterization of the reaction to brusone of brazilian wheat cultivars proves to be an important exploratory milestone in the evaluation of the reaction of wheat genotypes, which can help farmers to choose more resistant cultivars to brusone for their crops.

Dissolution of agrominerals by bioweathering provides nutrients for corn growth

Four microscopic images of biotite, a mineral. In all four images, something that looks like a plate of broken glass at different angles.

Pure and ground samples of biotite schist and biotite syenite proved to be sources of macro- and micronutrients for corn plants. The discovery is relevant for the future guidance of fertilization protocols, correction and soil balance to maximize production through the use of silicate agrominerals as soil remineralizers.

Hybridization with transcription factor AREB increases drought resistance in elite soybean cultivars

Rectangular horizontal photo. Plantation a bit blurred. Thin, tall branches, leaves that look like pods hanging from the branches. The plants look dry, but this may be due to lighting. In the background, strong and diffuse sun. The whole image is very yellowish and with strong shadows.

Soybean cultivation requires attention due to its susceptibility to drought. The introgression of the AtAREB1 transgene into the LS93-0375 and BMX Desafio RR elite cultivars conferred a better physiological performance to the genotypes, proving to be an effective mechanism of genetic engineering for the reduction of the effects of water deficit.
