The global energy crisis, driven by economic growth and the increasing demand for energy, highlights urgency of searching alternative sources to mitigate environmental pollution climate change. β-Glucosidases act in final step enzymatic hydrolysis cellulose, cleaving β-1,4-glycosidic bonds cellobiose produce second-generation ethanol. However, these enzymes are easily inhibited glucose, their product, which limits production this biofuel. Genetic engineering combined with bioinformatics...
The aim of this study was to evaluate variability nitrifying bacterial community in the biofilm and water a recirculating aquaculture systems (RAS) tilapia farming order determine if nitrification process is dependent, or not, bacteria abundance. Biofilm samples were collected periodically for 30 days analysed with fluorescent situ hybridization (FISH) technique, used quantify ammonia-oxidizing (AOB) nitrite-oxidizing (NOB). Ammonia presented peak first week, while nitrite's maximum recorded...
The production of glucose from cellulose requires cellulases, which are obtained decomposing microorganisms such as fungi and bacteria. Among the β-glucosidases convert cellobiose to have low concentration in commercial cocktails used for second-generation (2G) ethanol. Genetic engineering can be produce recombinant β-glucosidases, cyanobacteria may interesting bioreactors. These photosynthetic cultured using CO2 emitted first-generation ethanol (1G) industry a carbon source. In addition,...
Concepts from microbial ecology have been applied to constructing a bioreactor in RAS for the production of tilapia (Oreochromis niloticus). The consists covered and uncovered tanks, with without polyethylene net, separating participation photoautotrophic organisms other microorganisms capable absorbing nutrients. Absorption nutrients by macrophytes, planktonic algae bacteria was evaluated increase macrophyte biomass, density number bacterial cells respectively. Density adhering net roots...
Abstract Saponins are amphipathic glycosides with detergent properties present in vegetables. These compounds, when ingested, can cause difficulties absorbing nutrients from food and even induce inflammatory processes the intestine. There is already some evidence that saponins be degraded by β-glucosidases of GH3 family. In study, we evaluated, through computational tools, possibility a β-glucosidase (AMBGL17) obtained metagenomic analysis Amazonian soil, to catalytically interact saponin...
The vertical stratification of oxygen concentration in deep reservoirs impacts nutrient cycling and ecosystem biodiversity. Serra da Mesa reservoir, the largest Brazil, was studied to evaluate structure production prokaryote community at five depths. Using 3H leucine incorporation fluorescent situ hybridization (FISH), study focused on different depths near dam, particularly within euphotic zone. water column characterized into oxic, transitional, hypoxic layers based dissolved...
<title>Abstract</title> Bioremediation using plants and microorganisms effectively mitigates heavy metal soil contamination improves conditions. Phytoremediation with leguminous rhizobacteria enhances bioavailability promotes plant growth. This study evaluates microbial community structure in soils varying concentrations of tailings from the Fundão Dam disaster Mariana, MG, Brazil. Microbial diversity was measured by fluorescent situ hybridization treatments different presence...
Abstract Phosphorus is an essential mineral present in the vegetable matter form of phytate, which considered antinutritional factor. Phytate can be degraded by phytases, have been used commercial feeds. However, these enzymes undergo costly isolation and purification processes. In study, a genetically modified (GM) Bacillus subtilis strain that expresses fungal phytase was as feed additive. The GM probiotic added to shrimp Litopenaeus vannamei its effects on zootechnical performance,...
