Biodegradation of Diuron By Indigenous Soil Bacteria Isolated From Herbicide-contaminated SitesNARA Subscribed
Residual herbicides are widely used in weed management; however, their persistence in the environment can lead to agronomic and ecological impacts. This study assessed bacterial isolates obtained from sugarcane soil with a history of diuron exposure for their ability to increase diuron dissipation under controlled conditions. Forty-two bacterial isolates were obtained, of which 18 tolerated the commercial formulation at 1,000...
Promoter Engineering of the Surfactin Operon Enhances Surfactin Production in the Environmental Strain Bacillus subtilis RI4914NARA Subscribed
This study aimed to enhance surfactin production in Bacillus subtilis by replacing the native promoter of the surfactin synthase operon (P srfA ) with the strong IPTG-inducible promoter Pgrac to address challenges in large-scale biosurfactant production. The engineered strain was developed through homologous recombination, creating an integration cassette fused via overlap extension PCR and transformed into B. subtilis RI4914....
Morphometric characterization and decision tree–based prediction of phenotypic traits in Pantaneiro sheepNARA Subscribed
The Pantaneiro sheep is a locally adapted genetic resource shaped by the seasonal flooding, thermal stress, and heterogeneous forage availability of the Brazilian Pantanal. Characterizing its morphological structure using objective and field-applicable traits is essential for standardized phenotyping and conservation-oriented breeding strategies. This study evaluated 211 Pantaneiro ewes raised under semi-extensive management t...
Elucidating Metabolic Shifts in Thermophilic Biohydrogen Production: Effects of Inoculum Source, Pre-treatment and Substrate HydrolysisNARA Subscribed
Biohydrogen production through dark fermentation (DF) is a promising process that attracts increasing attention in the context of energy transition. However, a deeper understanding is necessary to enable its upscale to industrial applications. This study investigated DF using three inocula sources - anaerobic UASB sludge (PS), activated sludge (AS), and cow manure (CM) – all subjected to acid (APT) and thermal pretreatments (T...
Aim Understanding the factors determining marine community variations is important for biogeography and conservation. Beta diversity is a metric for mapping species composition variations between communities and regionalizing biota. Ecoregions are commonly used for regionalization, but their empirical testing has been limited. Our aim is to map marine species composition variations in the Western Atlantic, identify variables r...
Camera trap surveys of A tlantic F orest mammals: A data set for analyses considering imperfect detection (2004–2020)NARA Subscribed
Camera traps became the main observational method of a myriad of species over large areas. Data sets from camera traps can be used to describe the patterns and monitor the occupancy, abundance, and richness of wildlife, essential information for conservation in times of rapid climate and land‐cover changes. Habitat loss and poaching are responsible for historical population losses of mammals in the Atlantic Forest biodiversity...
