Introduction

Bacteria growth is a very important subject in microbiology and medical science. There is formula for determining reproduced bacteria from primary bacteria. In this formula we use log function, regeneration time and period time.

Formula is:

Logb= t*log2+(g*loga)/g

That t is period time,

Logb is reproduced bacteria,

Loga is primary bacteria

And g is regeneration time.

If t*log2+loga/g equals to Re, For calculate b you must follow it. b= 10^Re.

I wrote a program in VC++6 that calculate reproduced bacteria from primary bacteria. BacteriaGrowth method calculates it. This method defined in BacteriaGrowth.h file inside _BACTERIA structure. In this method nPrimary parameter is primary bacteria, reGenerationTime is Regeneration time for reproducing one bacterium to two bacteria and PeriodTime is total time for result.

Using the code

//
#include <windows.h>
#include <math.h>

typedef struct _BACTERIA
{
    double BacteriaGrowth(ULONG nPrime, 
        ULONG reGenerationTime, ULONG Period);
    
}BACTERIA;

//Retrurn Number of reproduced bacteria after periodtime 
//and with regenerationtime
double BACTERIA::BacteriaGrowth(ULONG nPrimary, 
            ULONG reGenerationTime,ULONG PeriodTime) 
{
    double Num=0;
    Num=(PeriodTime*log10(2)+(reGenerationTime*log10(nPrimary)))
        /reGenerationTime;
    return (double)powl(10,Num);
}
//

Points of Interest

BacteriaGrowth method is very useful for microbiology, medical and nutrition laboratory. for example: 3 bacteria while 4 hours(240 minutes) and after 15 minutes reproduce 196608 bacteria.
