Bioactive Compounds from Pecan Walnut Shells

Check if the same lab product or an alternative is used in the 5 most similar protocols

Pecan walnut shells (Carya illinoinensis) were collected at 1,090 above sea level (coordinates 25º45'32''N, 102º58'58''W) in San Pedro, Coahuila located on the north of Mexico. The shells were ground in a Wiley mill (Arthur Thomas, Philadelphia, PA) equipped with a 2 mm screen. Aspergillus oryzae 22788 was acquired from the American Type Culture Collection (ATCC).

Evaluation of Antimicrobial Compounds Against S. mutans

Check if the same lab product or an alternative is used in the 5 most similar protocols

Shikimic acid and gallic acid were commercially accessed from Sigma, Inc. S. mutans UA159 were obtained from the American Type Culture Collection (ATCC). The bacteria were cultured overnight in Brain Heart Infusion (BHI) broth (BD, Sparks, MD, USA) at 37°C for further experiments. BHIS (BHI broth containing 1% [wt/vol] sucrose) was used for biofilm assays. The negative control group was set as sterile phosphate-buffered solution (PBS) of the same volume as SA. The concentration of 0.2% (wt/vol) chlorhexidine was used as a positive control. The inhibition rates of planktonic cells or biofilm refer to the difference between the absorbance of the experimental group and the negative control group as a percentage of the absorbance of the negative control group.

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.
