Models of interactions between heterotrophic and autotrophic organisms

Interactions between heterotrophic plate count bacteria and coliform organisms.

Studies were initiated to investigate the interactions between heterotrophic plate count bacteria and coliform organisms. We used spiked samples to show that heterotrophic plate count bacteria could reduce coliform densities by more than 3 logs within 8 days. Some heterotrophic plate count bacteria were able to cause injury to the coliform population. A significant correlation (r = 0.66; P less...

Autotrophic, Heterotrophic and Other Nutritional Patterns

Autotrophic Micro-Organisms

ology. He also recognizes the role of chemotherapy, endocrinology, and improved instruments for observing the patient. His survey of current conditions is more detailed. Lord Horder is not only a physician interested in life and death, but also an adherent of such related causes as birth control and cremation. His interest in eugenics and biological control of illness has led him to try to get ...

Effects of Forest Age on Soil Autotrophic and Heterotrophic Respiration Differ between Evergreen and Deciduous Forests

We examined the effects of forest stand age on soil respiration (SR) including the heterotrophic respiration (HR) and autotrophic respiration (AR) of two forest types. We measured soil respiration and partitioned the HR and AR components across three age classes ~15, ~25, and ~35-year-old Pinus sylvestris var. mongolica (Mongolia pine) and Larix principis-rupprechtii (larch) in a forest-steppe ...

Ultrastructure of Nitrobacter agilis grown under autotrophic and heterotrophic conditions.

Nitrobacter agilis, grown through seven transfers heterotrophically in the absence of nitrite, was examined in the electron microscope. The ultrastructure of such cells closely resembled that of autotrophically grown N. agilis. It was thus futher established that the organisms growing heterotrophically were indeed N. agilis and, therefore, that N. agilis is a facultative autotroph. Acetate inco...
