Optimization and Modeling of Various Fermentation Parameters Influencing Liamocin Production by NBRC 100716 Strain.

Liamocins are unique extracellular glycolipid biosurfactants produced by certain species of with potential applications in agriculture, food, medicine, and pharmaceutical industries due to their surface-active properties and antimicrobial activity. In this study, for the first time, optimization of various fermentation parameters for liamocin production by NBRC 100716 strain was carried out using the response surface methodology (RSM). By conducting numeric optimization, the optimum conditions were determined as follows: initial substrate (fructose) concentration (1) of 93.

Characterization of the yeast flora present in some Turkish high-sugar products.

In this study, 129 Turkish high-sugar products were examined in terms of their yeast flora and 73 representative strains were isolated. Yeast isolates were identified at species level by using Apilab Plus (bioMérieux, France), a specific computer program developed for ID 32C strips (bioMérieux, France). While one of the isolates could be identified at genus level as Aureobasidium, 66 of them were identified as 21 species belonging to 8 different genera.
