Identification of microorganisms in wet coffee fermentation Coffea arabica Var Catimor and Castillo in Jardín, Antioquia-Colombia, using culture-dependent methods

Vitae (Medellín); 31 (1), 2024
Background: Mild Colombian coffees are recognized worldwide for their high-quality coffee cup. However, there have been some failures in post-harvest practices, such as coffee grain fermentation. These failures could occasionally lead to defects and inconsistencies in quality products and economic losses...

Análises bromatológicas de missô artesanal

J. Health Sci. Inst; 41 (2), 2023
Objetivo – Realizar análises bromatológicas de umidade, proteínas, pH e cinzas em missôs artesanais. A fermentação é um processo biotecnológico que tem sido utilizado para modificar e produzir alimentos desde a antiguidade. Nas últimas duas décadas, o interesse nos efeitos benéficos dos ferm...

Preparation of a probiotic quinoa beverage by enzymatic hydrolysis of its starches and subsequent lactic acid fermentation

Vitae (Medellín); 30 (2), 2023
Background: The concern about consuming healthy foods has increased in recent years. Not only are they expected to comply with essential feeding functions, but they also provide health benefits. Probiotics are one of the main functional components expected to be present in functi...

Significant production of vanillin and in vitro amplification of ech gene in local bacterial isolates

Braz. j. biol; 83 (), 2023
Abstract Vanillin is the major component which is responsible for flavor and aroma of vanilla extract and is produced by 3 ways: natural extraction from vanilla plant, chemical synthesis and from microbial transformation. Current research was aimed to study bacterial production of vanillin from native na...

Modulating the production of xylanase by Bacillus pumilus BS131 through optimization using waste fiber sludge

Braz. j. biol; 83 (), 2023
Abstract In recent days, cheapest alternative carbon source for fermentation purpose is desirable to minimize production cost. Xylanases have become attractive enzymes as their potential in bio-bleaching of pulp and paper industry. The objective of the present study was to identify the potential ability ...

Fungal decomposition of chicken-feather waste in submerged and solid-state fermentation

Braz. j. biol; 83 (), 2023
Abstract Poultry industry is expanding rapidly and producing million tons of feather waste annually. Massive production of keratinaceous byproducts in the form of industrial wastes throughout the world necessitates its justified utilization. Chemical treatment of keratin waste is proclaimed as an eco-des...

Optimized biotransformation of acid-treated water melon peel hydrolyzate into ethanol

Braz. j. biol; 83 (), 2023
Abstract Today, global focus of research is to explore the solution of energy crisis and environmental pollution. Like other agricultural countries, bulk quantities of watermelon peels (WMP) are disposed-off in environment as waste in Pakistan and appropriate management of this waste is the need of hour ...

Screening of lysine production by Escherichia coli and Klebsiella isolates at different carbon sources

Biosci. j. (Online); 39 (), 2023
Lysine is an essential amino acid that is not biologically manufactured in the body. Different chemical methods for lysine production are expensive and give low yields. The present study was conducted with the purpose to evaluate the biochemical production of lysine by different carbon sources using bact...

Evaluation of lactic acid fermentation in a dairy and non-dairy beverage using two commercial starter cultures

Vitae (Medellín); 29 (2), 2022
Background: Lactic fermentations are a catabolic process in which biochemical transformations of different organic products occur. Sugars are mainly converted into organic acids, increasing viscosity, acid taste, aroma, and flavor. Lactic acid bacteria provide probiotic characteristics if they reach coun...

Homeopathy on cultures of Saccharomyces cerevisiaeand impact on fermentation

Studies have shownthat homeopathy modulates the activity of both single-and multi-celled organisms;therefore, we propose a study into the action of Arnica Montanaand S. cerevisiae fungus nosode on growth “in vitro”, and on the fermentation of S. cerevisiaeon brewer’s wort. Methods:250 μL of medic...
