1. Psychrotrophic bacteria in Brazilian organic dairy products: identification, production of deteriorating enzymes and biofilm formation
Abstract The psychrotrophic bacteria count and the profile of Gram-negative bacteria present in commercial Brazilian organic dairy products (27 samples, pasteurized whole milk, Minas Frescal cheese, and yoghurt, equally distributed) as well as the biofilm-producing capacity and the production of deteriorating enzymes were investigated. Most of the samples (5

4. Pseudomonas SP. in uninspected raw goat’s milk in Rio de Janeiro, Brazil
Abstract Although quite controversial from the point of view of food safety, a considerable number of people across different age and socioeconomic groups consume raw goat’s milk. Even if refrigerated after milking, raw goat's milk may still be susceptible to the lipolytic and proteolytic actions of psychrotrophic microorganisms, such as Pseudomonas. In th

5. Unsatisfactory microbiological aspects of UHT goat milk, soymilk and dairy beverage of goat milk and soy protein: A public health issue
Abstract Spore forming bacteria can play an important role in food quality and safety as spoilage and pathogenic microorganisms due to resistance to heat-treatment. However, there are limited number of studies focused on evaluate the microbiological quality and the occurrence of these bacteria in UHT goat milk, soymilk and dairy beverage of goat milk and soy

6. Lactic acid bacteria with antimicrobial, proteolytic and lipolytic activities isolated from ovine dairy products
Abstract This study aimed to isolate lactic acid bacteria from sheep milk products and to characterize these microorganisms with a focus on their antimicrobial, proteolytic and lipolytic activities. Raw milk, pasteurized milk, pasteurized cream, and butter samples were collected, lactic acid bacteria were isolated and their proteolytic, lipolytic and antimic

7. Antimicrobial activity of propolis extract fractions against Staphylococcus spp. isolated from goat mastitis
RESUMO: O uso indiscriminado de antibióticos no tratamento de mastite caprina leva ao desenvolvimento de micro-organismos resistentes que poderão estar presentes em alimentos, colocando em risco a saúde humana. Dessa forma, a própolis surge como uma alternativa para o tratamento de doenças por possuir uma ação antimicrobiana, principalmente pela prese

9. Ocorrência de não conformidades físico-químicas e microbiológicas em leite e derivados no estado de Minas Gerais, no período de 2011 a 2015
ABSTRACT Milk and dairy products are potential sources for spoilage and pathogenic microorganisms, and although a huge amount of data is collected by the official inspection services, only a few reports are available to the public. This study aimed to evaluate the data for physicochemical and microbiological quality of pasteurized milk and dairy products, co
