“…The major objective of the study on PS II is to discover the structure of the complex with a view to understanding molecular mechanism of excitation energy transfer, electron transport, and O 2 -evolution. The new land of photosynthesis is first tread upon with the observation of dephlogistication (later identified to be evolution of oxygen gas) by plants (Priestley 1772). However, the concept of PS II came into existence only after Emerson enhancement effect (Emerson et al 1957) and the pioneering experiment on the antagonistic effect of light I and light II on the redox state of cytochrome f (Duysens et al 1961).…”

Photosystem II (PS II) of thylakoid membrane of photosynthetic organisms has drawn attention of researchers over the years because it is the only system on Earth that provides us with oxygen that we breathe. In the recent past, structure of PS II has been the focus of research in plant science. The report of X-ray crystallographic structure of PS II complex by the research groups of James Barber and So Iwata in UK is a milestone in the area of research in photosynthesis. It follows the pioneering and elegant work from the laboratories of Horst Witt and W. Saenger in Germany, and J. Shen in Japan. It is time to analyze the historic events during the long journey made by the researchers to arrive at this point. This review makes an attempt to critically review the growth of the advancement of concepts and knowledge on the photosystem in the background of technological development. We conclude the review with perspectives on research and technology that should reveal the complete story of PS II of thylakoid in the future.

“…In Stahl's (1697, p. 84) theory, heat is the motion of molecules, while phlogiston is a material principle; changes of state are not due to heat, and phlogiston is not heat. According to Stahl, there is 2 For example, Lavoisier possessed the 1757 French translation of Juncker's work as well as the 1730 original, Beretta (1995, p. 171), and the following Juncker quote appears to be the clear source for Lavoisier's (1774, p. 512) comment that Priestley's (1772) paper was a tissue of experiments hardly interrupted by any reasoning. 3 In the tradition of French books on chemistry, De Clave (1641) thought that fire was not an element but several phenomena and that air did not enter into compound bodies, so his five elements or principles were water, earth and mercury, sulphur and salt.…”

The development of problems within the phlogiston theories, 1766–1791

This is the first of a pair of papers. It focuses on the development of the most notable phlogistic theories during the period 1766-1791, including the main experiments that their proponents proposed them to interpret. There was a rapid proliferation of late phlogistic theories, particularly from 1784, and the accounts of composition and important implications of the main theories are set out and their issues analysed. Each of them either reached impasses due to internal problems, or included features that made them unacceptable even to other phlogistians. The expositions and analyses of these theories are given in terms of details that were in the literature at the time or otherwise potentially understandable by the participants given contemporary practice. Some relevant methodological aspects of the history of science are discussed, and the secondary literature is briefly surveyed. The second paper deals with the contemporary development of the new chemistry, and with theory comparison and theory choice in the same period.

“…Returning the container to the light allowed the candle to be relit. Also, mice placed in a container with a plant died when the container was placed in the dark, but survived if the container was illuminated (Priestley, 1773). Jean Sennebier, in 1782, showed that only green plants produced the gas.…”

Microbiological research in the days before specialized equipment, or even electricity, required a great deal of ingenuity. The revival of 90-year-old bioluminescent bacteria from Beijerinck's laboratory in Delft prompted a review of his work with these microorganisms and revealed their use in simple techniques for the investigation of, among other things, sugar metabolism in yeasts, oxygen generation and uptake and even the survival of microorganisms in liquid hydrogen. He used variant strains of bioluminescent bacteria in an attempt to study heredity and variation in biological systems and described one of the earliest examples of enzyme induction.
