Characterization of Microbial Population Shifts during Sample Storage
The objective of this study was to determine shifts in the microbial community structure and potential function based on standard Integrated Ocean Drilling Program (IODP) storage procedures for sediment cores. Standard long-term storage protocols maintain sediment temperature at 4°C for mineralogy, geochemical, and/or geotechnical analysis whereas standard microbiological sampling immediately p...
متن کاملEffects of Starter Culture and Storage Temperature on Functional, Microbial and Sensory Characteristics of Kefir during Storage
The aim of this study was to investigate the effects of starters and storage temperature (4 ºC, 25 ºC) onmicrobiological and physicochemical properties, volatile compounds and sensory evaluation of kefir.Kefirs produced by KFA and Chr. Hansen starters were stored at 4 ºC and 25 ºC for 40 days. pH andacidity at 4 ºC did not change (p ≥ 0.05), while at 25 ºC pH and total solid decreased as well a...
متن کاملEffects of genistein on melanosis and microbial quality of Litopenaeus vannamei during ice storage
Utilization of genistein as a natural inhibitor was studied alone and in combination with conventional treatments on melanosis and microbial quality of fresh L. vannamei during 10 days ice storage. Treatments were as followed: A (dipping samples in distilled water), B (dipping in 1.25 % sodium metabisulphite solution), C (dipping in 0.01 % genistein + 2% glycerol solution), D (dipping in 0.1 % ...

متن کاملCharacterization of the Fecal Microbiota Using High-Throughput Sequencing Reveals a Stable Microbial Community during Storage
The handling and treatment of biological samples is critical when characterizing the composition of the intestinal microbiota between different ecological niches or diseases. Specifically, exposure of fecal samples to room temperature or long term storage in deep freezing conditions may alter the composition of the microbiota. Thus, we stored fecal samples at room temperature and monitored the ...
