Characteristics of Bacillus subtilis HNMY-13 and HNMY-15 strains in aflatoxin B1 degradation and Astragalus bio-transformation
Astragalus of traditional Chinese medicine (TCM) and Bacillus subtilis are extensively used in animal feed and for production of various fermented compounds. In order to observe the characteristics of HNMY-13 and HNMY-15 B. subtilis strains, this study focused on the optimization of parameters in liquid fermentation of the two strains in aflatoxin B1 degradation, and Astragalus polysaccharide yield. The optimal...

The use of molecular markers in turtles: A technological prospecting
The application of molecular markers stands out in studies on the genetic variability of animal and plant species. This tool contributes to studies on the history of some chelonian species, since it takes into consideration their longevity and the endangerment they are often exposed to. The aim of the current study is to perform a quantitative research to document and analyze the development of technological...

Cloning and expression of acyl homoserine lactone (AHL) lactonase genes of Bacillus cereus INT1c and Bacillus thuringiensis SGT3g in Escherichia coli
Inhibition of virulence genes expression of phytopathogenic bacteria can be done by degrading the acyl-homoserine lactone (AHL) compounds using AHL-lactonase. In this study, the AHL-lactonase genes were cloned and expressed from Bacillus cereus INT1c and Bacillus thuringiensis SGT3g in Escherichia coli, in order to understand the characteristics and biocontrol mechanisms of their AHL-lactonase. Amplification using aiiA...

Evaluating chemical composition of Butia capitata pulp among various populations and locations using multivariate analysis
There are many native species from Cerrado that are used as food supply. However, their nutritional constitution is still unknown. The objective of this study was to evaluate and quantify the nutritional composition of coquinho-azedo fruits, obtained from different regions and populations in Northern Minas Gerais, using multivariate analysis. Ripe fruits of various B. capitata populations were obtained from four...

Synthesis of silver nanoparticles using wild Cucumis anguria: Characterization and antibacterial activity
In the present study silver nanoparticles were synthesized using wild Cucumis anguria leaf extract using the green route which is a simple, cost-effective and an environmentally friendly technique. When the aqueous silver ions were exposed to the wild C. anguria leaf extract, they were reduced and this resulted in the formation of silver nanoparticles. The conditions of synthesis were optimized by adjusting the pH, time...
