A Relationship Between Heterotrophic Utilization of Organic Acids and Bacterial Populations in West Blue Lake, Manitoba

A Relationship Between Heterotrophic Utilization of Organic Acids and Bacterial Populations in West Blue Lake, Manitoba

The relationship between the concentration of nine organic acid substrates (lactic, pyruvic, fumaric, malic, acetic, succinic, glycolic, citric, and formic) and their velocities of uptake has been investigated in West Blue Lake, Manitoba. Maximum uptake velocities were ranked and compared with bacte...

Description
Summary:The relationship between the concentration of nine organic acid substrates (lactic, pyruvic, fumaric, malic, acetic, succinic, glycolic, citric, and formic) and their velocities of uptake has been investigated in West Blue Lake, Manitoba. Maximum uptake velocities were ranked and compared with bacterial plate counts on minimal media supplemented with single organic acids. For pyruvic, fumaric, malic, acetic, glycolic, and citric acids an excellent correlation (r = 0.98) existed between plate counts and acid uptake indicating that for these substrates maximum velocities of uptake are indeed indicative of actual bacterial populations.
