Growth characteristics of low-nutrient bacteria from the north-east and central Pacific Ocean
Abstract Low-nutrient, or oligotrophic, marine bacteria, defined operationally as those which grow well in the dilute nutrient concentrations typical of natural seawaters, were found in waters of the eastern and central Pacific Ocean. All isolates tested grew in sterile unsuplemented seawater, ultra...

| 520 | |a Abstract Low-nutrient, or oligotrophic, marine bacteria, defined operationally as those which grow well in the dilute nutrient concentrations typical of natural seawaters, were found in waters of the eastern and central Pacific Ocean. All isolates tested grew in sterile unsuplemented seawater, ultraviolet-irradiated seawater, artificial seawater and charcoal-treated artificial seawater. Under optimal conditions, doubling times for low-nutrient bacteria were generally 2–5 h. Low-nutrient bacteria are heterotrophs responding to added organic substrates including glucose, proline, acetate, peptone, algal extract and yeast extract. Organic substrate concentrations (Ks values) necessary to yield half the maximum growth rates of low-nutrient bacteria ranged from 0.8–12 μg · 1−1 (0.2–4.9 μg C · 1−1). Bacterial inoculum size had little effect on doubling times, whereas low oxygen tensions and low temperatures reduced growth rates. Surfaces (glass beads) increased growth rates and maximum cell densities. The results of these laboratory studies indicate that low-nutrient bacteria play a major role in marine heterotrophic transformations of dissolved organic matter. | ||

Growth characteristics of low-nutrient bacteria from the north-east and central Pacific Ocean |
| abstract |
Abstract Low-nutrient, or oligotrophic, marine bacteria, defined operationally as those which grow well in the dilute nutrient concentrations typical of natural seawaters, were found in waters of the eastern and central Pacific Ocean. All isolates tested grew in sterile unsuplemented seawater, ultraviolet-irradiated seawater, artificial seawater and charcoal-treated artificial seawater. Under optimal conditions, doubling times for low-nutrient bacteria were generally 2–5 h. Low-nutrient bacteria are heterotrophs responding to added organic substrates including glucose, proline, acetate, peptone, algal extract and yeast extract. Organic substrate concentrations (Ks values) necessary to yield half the maximum growth rates of low-nutrient bacteria ranged from 0.8–12 μg · 1−1 (0.2–4.9 μg C · 1−1). Bacterial inoculum size had little effect on doubling times, whereas low oxygen tensions and low temperatures reduced growth rates. Surfaces (glass beads) increased growth rates and maximum cell densities. The results of these laboratory studies indicate that low-nutrient bacteria play a major role in marine heterotrophic transformations of dissolved organic matter. |
