The original concentration is 5.1 × 10⁹ CFU / ml
In order to attain a countable plate, the number of CFU must be present in between 10 and 200 per ml.
Let us take 0.1 ml and dilute it to 1 ml.
This minimizes the concentration to 5.1 × 10⁹ × 10⁻¹ = 5.1 × 10⁸ CFU/ml
In order to minimize the concentration in between 10 and 200, it can be reduced to 5.1 × 10¹
The final concentration = 5.1 × 10¹ CFU/ml
Initial concentration = 5.1 × 10⁹ CFU/ml
Volume of sample with 5.1 × 10¹ CFU = 5.1 × 10¹ CFU × (1 ml / 5.1 × 10⁹ CFU)
= 1.0 × 10⁻⁸ ml
This is the volume to be taken to obtain countable value, 51 CFU.
I hate to tell you this but this isnt tinder hunny
Acids give off H+ (Hydrogen) ions in water; bases give off OH- (Hydroxide) ions in water. Acids generally taste sour due to the sour H+ ion; bases taste bitter due to the OH- ion; but they may have other tastes depending on the other part of the molecule.
The mass of KCl per volume of solution=.35X(35.5+39)=26.075g/L
The amino acid chain will be; Lysine-Arginine-Cysteine
Amino acids are the building block of proteins, many amino acid molecules make up polypeptide chains which form proteins. Each amino acid is coded by a specific codon during the process of translation. A codon consists of three nucleotide bases. In this case AAG codes for amino acid Lysine, while AGA codes for Arginine and UGU codes for amino acid Cysteine.
