The study aimed at producing single-cell oil using Pseudomonas fluorescens bacteria and conducting solubility testing to confirm production estimate the content of produced from fatty acids, corn coalts were used as a carbon source applied optimal conditions forthe obtained previous study, amid liquid in experiment was extracted with saxolite device (Soxhletlet) ) We highest productivity by 55....

The hydrogen reacts with lactic acid to form propionic acid. Pyruvic acid has been isolated from the fermentation of glucose (1934) and of lactic acid (unpublished data) by Wood and Werkman. These investigators supported Van Niel's proposed dissimilation of pyruvic acid inasmuch as the occurrence of acetaldehyde could not be demonstrated. Little information is available concerning the aerobic d...

BACKGROUND Propionic acid is used primarily as a food preservative with smaller applications as a chemical building block for the production of many products including fabrics, cosmetics, drugs, and plastics. Biological production using propionibacteria would be competitive against chemical production through hydrocarboxylation of ethylene if native producers could be engineered to reach near-t...

We investigated whether 3-(trihydroxygermyl) propionic acid increases the formation of cornified cell envelopes and the level of ceramide in cultured epidermal keratinocytes and in a three-dimensional human epidermis model. The activity and mRNA expression of transglutaminase were increased when 3-(trihydroxygermyl) propionic acid was added to the cell cultures. The formation of cornified cell ...

The article presents the features of conservation leafy mass high-protein crops legume family, disadvantages traditional preparation biomass for silage in fodder production. results studying possibility reducing plant moisture by mechanical means, using press residue as a raw material making haylage, and brown juice preservative are presented. development method pressed alfalfa with introductio...

The aim of this study was to determine the effect of molasses and lactic acid bacteria (LAB) on the chemical composition, silage fermentation characteristics, and in vitro ruminal fermentation parameters of an ensiled potato-wheat straw mixture in a completely randomized design with 4 replicates. Wheat straw was harvested at full maturity and potato tuber when the leaves turned yellowish. The p...

Propionic acid (propionate) is a commercially valuable carboxylic acid produced through microbial fermentation. Propionic acid is mainly used in the food industry but has recently found applications in the cosmetic, plastics and pharmaceutical industries. Propionate can be produced via various metabolic pathways, which can be classified into three major groups: fermentative pathways, biosynthet...

AIMS To evaluate the interaction between selected yeasts and bacteria and associate their metabolic activity with secondary cucumber fermentation. METHODS AND RESULTS Selected yeast and bacteria, isolated from cucumber secondary fermentations, were inoculated as single and mixed cultures in a cucumber juice model system. Our results confirmed that during storage of fermented cucumbers and in ...
