Modified chemically defined medium for enhanced respiratory growth ofLactobacillus caseiandLactobacillus plantarumgroups

Abstract

The availability of mCDM will facilitate the study of aerobic metabolism of lactobacilli under controlled conditions.

Tween 80 and respiratory growth affect metabolite production and membrane fatty acids inLactobacillus caseiN87

“…; Ricciardi et al . ) were assimilated in all conditions. The uptake of l ‐asparagine, l ‐proline and l ‐serine (added to CDMo of Ricciardi et al .…”

“…The uptake of l ‐asparagine, l ‐proline and l ‐serine (added to CDMo of Ricciardi et al . , but considered unessential and missing in the others CDM), clearly depended on the type of cultivation: a net production was observed in anaerobic cultures (both AN−Tw and AN+Tw), while a net consumption was observed in RS−Tw growing cultures. In respiratory cells supplemented with Tween 80 (RS+Tw), instead, only l ‐proline was extensively consumed.…”

“…Besides, only a few studies (Ricciardi et al . , ) have evaluated the differences in metabolic pathways and nutritional requirements of lactobacilli during anaerobic (AN) and respiratory growth. In this work, the CDMo of Ricciardi et al .…”

“…In this work, the CDMo of Ricciardi et al . () was used to investigate the effect of Tween 80 and respiratory growth (air, hemin and menaquinone) on the production of organic acids, volatile organic compounds (VOCs), amino acid uptake and membrane FA composition of the respiration‐competent strain Lact. casei N87, in order to clarify the metabolic and physiological consequences of respirative cultivation.…”

Development of a Chemically Defined Medium for Better Yield and Purification of Enterocin Y31 fromEnterococcus faeciumY31

“…Ricciardi reported a modified chemically defined medium to promote the growth of Lactobacillus casei and Lactobacillus plantarum groups [15]. In the present study, we improved the chemically defined medium to improve the yield of Enterocin Y31 produced by E. faecium Y31.…”
