Furthermore, we used an age-specific population dynamic model, parameterized using individual life-history assays, to successfully predict the growth of populations over three generations. This study paves the way for more detailed and quantitative experimental investigation of the ecology and evolution ...
200 nm. All imaging experiments were repeated three times with similar results.bPhotographs of agar plates ofS. aureus(SA),M. luteus(ML),E. coli(EC),P. aeruginosa
Consistent with the growth curve results, there was no notable difference in viability between uncoated EcN and CMCB (Fig. 1f). Additionally, cells were stained with propidium iodide (PI) and imaged to evaluate the number of dead cells. LSCM imaging indicates that the bacteria were able to ...
Danino found he was able to manipulate them into creating certain patterns. For instance, the optimal temperature for growth of many bacteria is 37 degrees Celsius, which is, unsurprisingly, the temperature of the human body. If it’s hotter or colder than 37 degrees, bacteria...
Agar diffusion techniques are used widely to assay plant extracts for antimicrobial activity, but there are problems associated with this technique. A micro-dilution technique was developed using 96-well microplates and tetrazolium salts to indicate bacterial growth, P-lodonitrotetrazolium violet [0.2 mg...
Alginase-secreting bacteria associated with actively growing tissues of the marine Phaeophyta species Sargassum fluitans and S. natans have been isolated and evaluated for their ability to degrade alginate (ALG), carboxymethylcellulose, and agar. Of seven isolates selected for their ability to grow on...
However, plate count agar does not permit the growth of many bacteria that may be presen... DJ Reasoner,EE Geldreich - 《Appl Environ Microbiol》 被引量: 3225发表: 1985年 Survival strategies of bacteria in the natural environment. The need for methods to estimate accurately and reliably the ...
In terms of making the bed, essential oils use was correlated with lower airborne fungi. Essential oils containing terpenoids of essential oils that can inhibit the growth of fungi (Yang and Clausen, 2007; Ćosić et al., 2010; Schroder et al., 2017) and absorption of vapors of essential...
Due to high yields of material being produced from simple static growth cultures, microbial production of BC is very amenable to scale-up, enabling the amount of BC required to build real products to be achieved with minimal infrastructure investment. This has made BC attractive to producers at ...
it was found that the addition of the simulant had no obvious effect on the growth and reproduction of five PSBs in the early stage of culture. The growth curves of the five PSBs almost coincided with their corresponding control, from the inoculation to the pre-logarithmic and mid-logarithmic...
