BACKGROUND The aromatic compounds cinnamic acid (CA) and p-hydroxycinnamic acid (pHCA) are used as flavoring agents as well as precursors of chemicals. These compounds are present in plants at low concentrations, therefore, complex purification processes are usually required to extract the product. An alternative production method for these aromatic acids is based on the use of microbial strain...

Mango juice (MJ) was co-inoculated with Lactobacillus plantarum + Rhodotorula glutinis or Metschnikowia pulcherrima (LP RG LP MP, respectively) and casei (LC LC to evaluate their effect on the physicochemical characteristics, antioxidant capacity, aroma compounds of MJ after 72 h fermentation at 28 °C. Results indicated that among fermented MJ, which yielded highest content total acid (15.05 g/...

2,3-Butanediol (2,3-BD) is a valuable bulk chemical owing to its extensive application in chemical and pharmaceutical industry with diverse applications in drug, cosmetics and food products. In the present study, the biotransformation of acetoin to 2,3-BD by five plant species (Brassica oleracea, Brassica rapa, Daucuscarota, Pastinaca sativa, and Raphnussativus) and five microorganisms (Aspergi...

Sir: Pepsin inhibitor (S-PI), produced by Streptomyces naniwaensis, was found to be an acylpentapeptide with MW 643.1•`4) It in hibited not only pepsin but also acid proteases that are widely produced by various yeasts and fungi, by the formation of a protease-inhibitor complex. The authors intend to make use of S-PI, and therefore aerobically cultured an acid protease producing organism, Rho d...
