The e ffect of microgravity on the growth and ph of l actobacillus acidophilus

The Effect of Microgravity on the Growth

and pH of Lactobacillus acidophilus

Presidio High School

Teacher Facilitator: Melody Crowder

Principal Investigator: Illiana Fernandez

Co-Principal Investigator- Alvaro Ali Romero

Collaborator- Rafael Sanchez


Lactobacillus acidophilus

Lactobacillus acidophilus

  • Grows in 5.0-7.0 pH

  • Reproduces rapidly

  • Naturally found in the human intestines


Objective

Hypothesis

Objective

  • The growth rate will slow down and the pH will increase.

  • Test the effects of microgravity on the growth rate and pH of Lactobacillus acidophilus bacteria.

  • Determine if astronauts should be given supplemental probiotics

Purpose


Procedure

Procedure

  • Main Volume: Distilled Water

  • Ampoule A: powdered

    lactobacillus acidophilus

    and powdered milk.

  • Ampoule B: Formalin

  • The L. acidophilus will be rehydrated in the same time frame in microgravity as our ground truth experiment.


Procedure1

Procedure

Bacteria will be counted and compared to the ground truth experiment.


Limitations

Limitations

  • Remote location of Presidio ISD

  • Size of FMEcan not store enough nutrients for 90 days

MEXICO


Real world applications

Real World Applications

  • Give supplemental probiotics to astronauts

    • Aid in production of Vitamin K

    • Improve digestion and overall health

    • Supports a healthy immune system
