THE CHEMICAL COMPOSITION OF CHLORELLA; EFFECT OF ENVIRONMENTAL CONDITIONS.

摘要: The purpose of the investigations here described was to determine what extent chemical composition a plant can be altered by growing it under different environmental conditions. three general processes which organic are photosynthesis, respiration, including aerobic and anaerobic catabolism, biosynthesis. In present state knowledge is difficult discern these interrelated. For immediate purposes this investigation is, in fact, not essential attempt may responsible for any observed changes composition. If decided observable as results conditions, effects then further analyzed perhaps ultimately ascribed one or another major processes. problem discover conditions would, when altered, affect plant, nature magnitude effect. objective find would materially modify relative proportions constituents, carbohydrates, proteins lipids. such an undertaking, very little information available basis working hypothesis aid choice It obvious from outset, therefore, that large number experiments have made. requiring many analyses, determination plants terms definite compounds, even groups laborious time consuming. Regarding all carbon arising reduction of, dioxide, we were more concerned with energy level total matter than isolation particular constituents. heat combustion material measure, satisfy requirement; but data limited usefulness.
