The aim of this research effort was to investigate the role various sugar substrates in growth medium upon thermotolerance and survival during storage after freeze-drying Lactobacillus bulgaricus. Addition sugars tested medium, these sorbitol drying (skim milk) investigated so as determine whether a relationship exists between media, terms protection freeze-dried cells throughout storage. lowest decrease viability L. bulgaricuscells obtained when that organism grown presence mannose....
Abstract Industrial scale-up of microalgal cultures is often a protracted step prone to culture collapse and the occurrence unwanted contaminants. To solve this problem, two-stage process was developed – heterotrophically Chlorella vulgaris cells grown in fermenters (1 st stage) were used directly inoculate an outdoor industrial autotrophic production unit (2 nd stage). A preliminary pilot-scale trial revealed that C. adapted readily growth conditions (1-m 3 photobioreactors) without any...
The demand for sustainable and environmentally friendly food sources ingredients is increasing, microalgae are promoted as a source of essential bioactive lipids, with high levels omega-3 fatty acids (ω-3 FA), comparable to those fish. However, most FA screening studies on algae scattered or use different methodologies, preventing true comparison its content between microalgae. In this work, we used gas-chromatography mass-spectrometry (GC-MS) characterize the profile seven commercial...
Microalgae are widely used as food supplements due to their high protein content, essential fatty acids and amino well carotenoids. The addition of microalgal biomass products (e.g., baked confectioneries) is a common strategy attract novel consumers. However, organoleptic factors such color, taste smell can be decisive for the acceptability foods supplemented with microalgae. aim this work was develop chlorophyll-deficient mutants Chlorella vulgaris by chemically induced random mutagenesis...
Microalgae have been described as a source of bioactive compounds, such peptides. are easy to produce, making them sustainable resource for extracting active ingredients industrial applications. Several microalgae species interesting protein content,
The nutritional requirements of novel microalgal strains are key for their effective cultivation and metabolite content. Therefore, the optimization heterotrophic photoautotrophic culture media is crucial Chlorococcum amblystomatis growth. Heterotrophic biomass samples were characterized to identify differences between composition biotechnological potential. Media through surface response methodology led 44.9 51.2% increments in C. amblystomatis-specific growth rates under growth,...
Aims: Cell survival and antagonistic activity against Listeria innocua, monocytogenes Staphylococcus aureus were investigated after spray‐drying three bacteriocin‐producing strains of lactic acid bacteria: Carnobacterium divergens, Lactobacillus salivarius sakei. Methods Results: Bacterial cell concentrates spray‐dried stored at 4°C 18°C 0·3% ERH (equilibrium relative humidity). Enumeration evaluated before regular intervals during storage. Conclusions: A higher rate was obtained when...
This work aims to investigate the survival of Lactobacillus kefir CIDCA 8348, plantarum 83114 and Saccharomyces lipolytica 812, all isolated from kefir, during spray drying subsequent storage.Micro-organisms were grown in De Man, Rogosa, Sharpe (MRS) or yeast medium (YM) harvested stationary phase growth. The thermotolerance skim milk (D Z values), at different outlet air temperatures storage conditions 150 days studied. resistance heat treatments was higher Lact. compared S. lipolytica....
