Mining projects are often budgeted in millions of dollars, making it of interest to the investor to measure a project's uncertainties and risks, which include the changes in the commodity price. The simulation of asset prices is valid because it enables displaying, with a degree of certainty, the future behavior of a financial asset. One of the most commonly used mathematical forecast models is the Geometric Brownian Motion (GBM) model. This article aims at simulating the forecast price of an iron ...

Microbial activity is an integral part of agricultural ecosystems and can influence the quality of food commodities. During on-farm processing, coffee growers use a traditional method of fermentation to remove the cherry pulp surrounding the beans. Here, we investigated the influence of the coffee farm microbiome and the resulting fermentation process conducted with selected starter cultures (Pichia fermentans YC5.2 and Pediococcus acidilactici LPBC161). The microbiota of the coffee farm (coffee fruits ...

The emergence of Coronavirus disease 2019 as a global pandemic has increased popular concerns about diseases caused by viruses. Fermented foods containing high loads of viable fungi and bacteria are potential sources for virus contamination. The most common include viruses that infect bacteria (bacteriophage) and yeasts reported in fermented milks, sausages, vegetables, wine, sourdough, and cocoa beans. Recent molecular studies have also associated fermented foods as vehicles for pathogenic human ...

Complex carbohydrates, proteins, and other food components require a longer digestion process to be absorbed by the lining of the alimentary canal. In addition to the enzymes of the gastrointestinal tract, gut microbiota, comprising a large range of bacteria and fungi, has complementary action on the production of digestive enzymes. Within this universe of "hidden soldiers", lactobacilli are extensively studied because of their ability to produce lactase, proteases, peptidases, fructanases, amylases, ...

Fermentation is an important step in coffee processing which promotes the removal of mucilage adhering to the fruits. This process has a direct impact on the coffee quality, and the use of bioreactors and starter cultures has been suggested for process control. In this study, a techno-economic analysis was performed to assess the investment costs and economic performance of the inclusion of a stirred tank bioreactor (STB) model and starter cultures into a coffee processing plant. The total capital ...

During coffee processing, lactic acid bacteria (LAB) from multiple ecosystems (water, native soil, air, and plant) find in the cherry pulp a rich environment for their development. They utilize pulp substrate as a source of carbon and nitrogen to produce significant amounts of lactic acid. This natural fermentation is purposely used by coffee growers to promote an efficient removal of the mucilage layer adhering to the fruits, before storage and transport of the coffee beans. Besides lactic acid, ...

The skin microbiome is composed of a complex association of bacteria, fungi, and viruses. The maintenance of skin commensal microbes is essential for preventing the overgrowth of pathogenic microorganisms or already present opportunistic pathogens. Thus, the development of bioactive compounds capable of modulating skin microbiome has become an important topic for both researchers and the cosmetic industry. Increasingly, scientific evidence highlights that metabolites derived from probiotics have ...

Abstract This work aimed at studying the unconfirmed hypothesis predicting the existence of a connection between coffee farm microbiome and the resulting spontaneous fermentation process. Using Illumina‐based amplicon sequencing, 360 prokaryotes and 397 eukaryotes were identified from coffee fruits and leaves, over‐ripe fruits, water used for coffee de‐pulping, depulped coffee beans, soil, and temporal fermentation samples at an experimental farm in Honduras. Coffee fruits and leaves were mainly ...

Removal of the mucilage layer of coffee fruits by a fermentation process has became an interesting strategy to improve coffee quality, which is able to assist the formation of flavored molecules. In this study, four sets of inoculation protocols were evaluated using ripe and immature coffee fruits, respectively, including (i) pure culture fermentation with Pichia fermentans, (ii) pure culture fermentation with Pediococcus acidilactici, (ii) combined fermentation with P. fermentans and P. acidilactici, ...

This study analyzes homicide incidence per municipality (county) in Brazil in the year 2008. The authors estimate and compare homicide rates according to different methods, finding evidence that depending on the method employed, the results can differ significantly, especially for small municipalities. Bayesian spatial procedures were employed, allowing minimization of variation in the rate estimates. The methods consider a priori distributions and information on contiguity of municipalities. According ...

Omega-3 produced by marine thraustochytrids has appeared as an alternative to fish oil and an eco-friendly solution to overfishing. Herein, an integrative analysis of metagenetics and high-throughput screening was used for bioprospecting marine thraustochytrids from southern Brazil mangrove and coastal seawater. All sampled environments showed biodiversity and abundance of SAR clade. Environmental samples detected with potential lipid-accumulating labyrinthulomycetes were further processed for direct ...

This paper presents an experiment with four different convolutional neural networks architectures that aim to classify segments of a sheep using a dataset of superpixels. The proposal used an image dataset with 512 images of 32 sheep. In this dataset of images, we applied the Simple Linear Iterative Clustering technique with a K number parameter of 600 to generate the dataset of superpixels that was later processed in the deep neural networks. We selected four architectures for training the models: ...

Post-harvest coffee processing involves a microbial process to remove the mucilage layer adhering to the fruits, prior to storage and transport of the coffee beans. In this study, coffee mucilage removal was done using lactic acid fermentation in a stirred-tank bioreactor (STR). Fermentation assays were done with or without the addition of starter culture (i.e., Lactobacillus plantarum LPBR01), and kinetic parameters, including microbial growth, sugar pulp consumption and metabolite production, were ...

The aim of this study was to evaluate the yeast diversity and physicochemical characteristics of spontaneous coffee bean fermentation conducted in the coffee-producing region in Cerrado Mineiro, Brazil. During 48 h of fermentation, yeast population increased from 6.60 to 7.89 log CFU·g−1, with concomitant pulp sugar consumption and organic acids production (mainly lactic (3.35 g·L−1) and acetic (1.27 g·L−1) acids). According to ITS-rRNA gene sequencing, yeast population was mainly represented by Saccharomyces ...

In order to determine whether southern Amazonian bats could harbour hantaviruses we, serologically and molecularly, screened blood, saliva, excreta and organ tissues of 47 bats captured from September to December 2015. We found that only phyllostomid bats presented antibodies against hantavirus. The seropositive bats belonged to two species of Phyllostomid bats: the greater spear-nosed bat Phyllostomus hastatus (omnivorous) and the gnome fruit-eating bat Dermanura gnoma. The overall seroprevalence ...
