BIOLUMINESCENCE AND OTHER CHARACTERISTICS OF COLLYBIA VELUTIPES

Abstract

The growth in terms of linear extension and dry weight, endogenous respiration, bioluminescence and ATP concentration of Collybia velutipes has been considered. After an initial lag phase of approximately 4 days, linear growth extension with time is obtained. Dry weight measurements, however, indicate that secondary activity in previously formed cells occurs. One such activity is the formation of glycogen. The presence of glycogen, as determined by electron microscopy and several chemical tests, has been established in C. velutipes. Optimal endogenous respiratory activity occurs in tissue less than 48 hr of age, while maximal bioluminescent activity occurs in tissue that is 2–6 days in age. The maximum ATP concentration occurs in tissue approximately 7 days old.
