  • Bacteria-phosphate interactions in Upper Klamath Lake sediments

    Creator:
    Harrison, Michael John
    Abstract:
    Interactions between sediment bacteria and available phosphate necessary for algal production in a eutrophic lake were studied. Twenty percent of the organisms isolated solubilized phosphate forms such as CaHPO₄, Ca₃(PO₄)₂, FePO₄, Mg₃(PO₄)₂ and Al₂(PO₄)₂. Solubilization of phosphates occurred under conditions of aerobic growth. Upon quantitative analysis, some isolates were capable...

  • Vitamin B₁₂ production and depletion in a naturally eutrophic lake

    Creator:
    Gillespie, P. A.
    Abstract:
    The vitamin B₁₂ concentrations in both the water and sediments of Klamath Lake were found to vary significantly during a one-year period. The patterns of B₁₂ distribution were remarkably similar among the three main sites. In all cases there was an extremely sharp gradation in concentration in relation to depth...
