Marine Bacteria Quorum Sensing Inhibition

Check if the same lab product or an alternative is used in the 5 most similar protocols
The marine bacterial strains analysed in this study are summarized in Table 2. Marine agar or broth (MA or MB respectively) was routinely used to grow marine bacterial strains (Difco, Oxford, UK). SYP agar with 1.5% of sea salt and MA or MB were used in different experiments performed in this work to analyse the potential QSI capability of marine bacteria. All marine bacterial strains used in this study were grown routinely at 23°C. Different N‐Acyl homoserine lactones (AHLs) used in this work were purchased from Sigma‐Aldrich (Cambridge, UK) and were dissolved in DMSO (N‐butyryl‐dl‐homoserine lactone: C4‐HSL; N‐hexanoyl‐l‐homoserine lactone: C6‐HSL; N‐(3‐oxooctanoyl)‐l‐homoserine lactone: 3OC8‐HSL; N‐(3‐oxodecanoyl)‐l‐homoserine lactone: 3OC10‐HSL; and N‐(3‐oxododecanoyl)‐l‐homoserine lactone: 3OC12‐HSL).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
