Factors Limiting Bacterial Growth
Simple assumptions have led to equations by which the latent period in multiplication and the bacterial numbers expected at any time during the phase of rapid growth may be predicted. Experimental data obtained under rather diverse conditions have given satisfactory agreement with calculated values. Since the mathematical expressions contain no arbitrary constants, more than accidental signific...
متن کاملRapid method of determining factors limiting bacterial growth in soil.
A technique to determine which nutrients limit bacterial growth in soil was developed. The method was based on measuring the thymidine incorporation rate of bacteria after the addition of C, N, and P in different combinations to soil samples. First, the thymidine incorporation method was tested in two different soils: an agricultural soil and a forest humus soil. Carbon (as glucose) was found t...
متن کاملFactors limiting heterotrophic bacterial production in the southern Pacific Ocean
The role of potential factors limiting bacterial growth was investigated along vertical and longitudinal gradients across the South Eastern Pacific Gyre. The effects of glucose, nitrate, ammonium and phosphate additions on heterotrophic bacterial production (using leucine technique) were studied in parallel in unfiltered seawater samples incubated under natural daily irradiance. The enrichments...
متن کاملModeling of Bacterial Growth under Multiply - Limiting Conditions . Experiments under Carbon - or / and Nitrogen - Limiting Conditions
As the limiting substrate is altered, a microorganism’s internal structure is also altered by invoking different metabolic pathways for the utilization of the limiting substrate. Transitions between pathways are moderated by the processes of metabolic regulation and are observed under steady-state and transient conditions. Under nitrogen-limited steady-state conditions, the effects of overflow ...
متن کاملLimiting and Experimental Factors
Practical applications of phytoremediation are essential for the clean-up of moderately and severely contaminated sites in an economical and environmentally responsible way. The usage of plants to do a job that would otherwise be done by chemicals or energy intensive soil removal is a natural choice on several levels. First, by using plants for clean-up, pollutants are being absorbed by nature ...
