Acid into Different Sizes of Agar Blocks Aim: Investigating the relationship between the diffusion and the surface area to volume ratio‚ with agar and hydrochloric acid. Research Question: How does the difference in surface area to volume ratio affect the diffusion? Hypothesis: As the area to volume ratio increases‚ the time taken for a complete diffusion will also increase. Background Information: Agar is a jelly like substance and in this experiment‚ agar will be used is containing

Isolation and Purification of Lyngbya majuscula on Nutrient-enriched Agar Plates A Special Problem Isolation and Purification of Lyngbya majuscula on Nutrient-enriched Agar Plates ABSTRACT Lyngbya majuscula samples were obtained from the Phycology Laboratory stock culture of the UPV Institute of Aquaculture. Five (5) mm fragments of these were inoculated into agar plates that used 1% agar concentration enriched with varying concentrations (1.0%‚ 1.5%‚ and 2.0%) of Hughes‚ et

FACT: Potassium tellurite (K2TeO3) inhibits the growth of gram-negative bacteria and most of the upper respiratory tract normal flora. Oxyanions of tellurium‚ like tellurite (TeO32-)‚ are highly toxic for most eukaryotic and prokaryotic organisms. Known for its antimicrobial properties‚ potassium tellurite has been used in selective media for the isolation of a number of naturally tellurite-resistant bacterial species such as the C. diphtheriae. These tellurite-resistant bacteria reduce tellurite

Methylene Blue on Agar Plates at Different Temperatures Abstract: Diffusion is the movement of particles from an area of high concentration to an area of low concentration wherein substances are independent‚ rapid and in random motion which frequently collide with each other in the sides of the container. This study aimed to assess the influence of temperature on the diffusion rate of methylene blue on agar plates. To determine the relationship between the two variables‚ five set-ups of agar plates were
