In one respect, the variable-yield model has been a disappointment in the sense that it was hoped that the transient behavior of its solutions would better fit the transient behavior seen in experiments with certain algae [CNIJ. The experiments, described in [CM], involved the growth of a Chlamydomonas reinhardii population on a nitrogen substrate. Following a step increase in the dilution rate, damped oscillations were observed in cell numbers. Cunningham and Nisbet [CNl] note that the singlepopulation variable-yield model could not reproduce these oscillations without the introduction of time delays into the equations. See also the monograph [NG].

The ESR signal of Af, 2 could be observed in membrane preparation from a strain of Chlamydomonas reinhardii lacking PSI. The broad peak at g = 1.84 is again similar to what observed in bacterial RC and suggests a plastoquinone-Fe complex [87]. Also similar is the inhibitory effect of o-phenanthroline [88].

Hydroxyprolyl glycopeptides have also been found in lower plants such as ferns and algae (Lamport and Miller, 1972). In the green algae Chlamydomonas reinhardii the pattern of glycosylation is different (O Neill... 

Similarly, chemotactic behaviour of bacteria is controlled by Ca . Mobile bacteria swim towards certain chemicals and away from others. Such bacteria can swim smoothly in a straight line or tumble, which results in random changes in direction. When heading towards repellents bacteria tumble more frequently to increase the probability of swimming away. Influx of Ca causes tumbling. Such behaviour has been found for Bacillus subtilis but apparently not for E. co/i. Calcium accelerates the swimming speed of Chlamydomonas reinhardii and regulates reverse motion in phototactically active Phormidium uncinatum and Halobacterium halobium. Phototaxis in H. halobium involves a methylation-demethylation process which is calcium dependent. Attractant stimuli raise the level of methylation of membrane proteins, while repellent stimuli cause demethylation and the enhanced opportunity for reversal of direction. Ca " " deactivates the methyl transferase and activates a methyl esterase. ...
