ABSTRACT
The gastrointestinal microflora regulates the body's functions and plays an important role in its health. Dysbiosis leads to a number of chronic diseases such as diabetes, obesity, inflammation, atherosclerosis, etc. However, these diseases can be prevented by using probiotics living microorganisms that benefit the microflora and, therefore, improve the host organism's health. The most common probiotics include lactic acid bacteria of the Bifidobacterium and Propionibacterium genera. We studied the probiotic properties of the following strains: Bifidobacterium adolescentis ÐС-1909, Bifidobacterium longum infantis ÐС-1912, Propionibacterium jensenii Ð-6085, Propionibacterium freudenreichii Ð-11921, Propionibacterium thoenii Ð-6082, and Propionibacterium acidipropionici Ð-5723. Antimicrobial activity was determined by the 'agar blocks' method against the following test cultures: Escherichia coli ATCC 25922, Salmonella enterica ATCC 14028, Staphylococcus aureus ATCC 25923, Pseudomonas aeruginosa B6643, Proteus vulgaris ATCC 63, and Listeria monocytogenes ATCC 7644. Moderate antimicrobial activity against all the test cultures was registered in Bifidobacterium adolescentis ÐС-1909, Propionibacterium jensenii Ð-6085, and Propionibacterium thoenii Ð-6082. Antioxidant activity was determined by the DPPH inhibition method in all the lactic acid strains. Our study indicated that some Propionibacterium and Bifidobacterium strains or, theoretically, their consortia could be used as probiotic cultures in dietary supplements or functional foods to prevent a number of chronic diseases.
A microbiota gastrointestinal regula as funções do corpo e desempenha um papel importante na sua saúde. A disbiose leva a uma série de doenças crônicas, como diabetes, obesidade, inflamação, aterosclerose, etc. No entanto, essas doenças podem ser prevenidas pelo uso de probióticos − microrganismos vivos que beneficiam a microflora e, portanto, melhoram a saúde do organismo hospedeiro. Os probióticos mais comuns incluem bactérias do ácido láctico dos gêneros Bifidobacterium e Propionibacterium. Nós estudamos as propriedades probióticas das seguintes cepas: Bifidobacterium adolescentis ÐС-1909, Bifidobacterium longum infantis ÐС-1912, Propionibacterium jensenii Ð-6085, Propionibacterium freudenreichii Ð-11921, Propionibacterium thoenii Ð-6082 Ð-6082 acid e Propionibacterium thoenii Ð-6082 Ð-6082 acidibion. A atividade antimicrobiana foi determinada pelo método de 'blocos de ágar' contra as seguintes culturas de teste: Escherichia coli ATCC 25922, Salmonella enterica ATCC 14028, Staphylococcus aureus ATCC 25923, Pseudomonas aeruginosa B6643, Proteus vulgaris ATCC 63 e Listeria monocytogenes moderada atividade ATCC 7644. Uma atividade antimicrobiana moderada contra todas as culturas de teste foi registrado em Bifidobacterium adolescentis ÐС-1909, Propionibacterium jensenii Ð-6085 e Propionibacterium thoenii Ð-6082. A atividade antioxidante foi determinada pelo método de inibição do DPPH em todas as cepas de ácido lático. Nosso estudo indicou que algumas cepas de Propionibacterium e Bifidobacterium − ou, teoricamente, seus consórcios − poderiam ser usadas ââcomo culturas probióticas em suplementos dietéticos ou alimentos funcionais para prevenir uma série de doenças crônicas.
