ABSTRAM In the reaction of the reversible photoreduction of ohloro-
phyll and of its analogues the excited molecule receives
one electron from the donor molecule, a pair of ion radi-
cals being formed by this process. This reamtion is easily
reversible and after the electron transfer an acid-base
equilibrium is established acoording to the properties of
the medium. The latter is connected with a subsequent proton
transfer and with the formation of more stable reduced forms,
which "accumulate" the energy of light quanta. An accumula--
tion of such photoreduced pigment forms is only found in
media with a certain basicity. The authors investigated the
Card 1A velocity of the reverse reaction of the photoreduced pigment

forms and their absorption spectra in media with a varying
basicity, in this instance proceeding from the same concep-
tions. For this purpose distilled pyridine and piperidine
and ammonia water solution were used. An evacuated tube with
a reaction wixture was illuminated by a cine-lamp with 500
Watts at 2o for the purpose of photoreduotion. In a second
experimental variant the base was only introduced after air
had been admitted. It can be seen from Table I that the said
reaction of chlorophyll regeneration from its photoreduced
form with an absorption maximum at 52o mp proceeds relative-
ly slowly. After the introduction of a strong base (piperi.,
dine or ammonia) the absorption at 52o mp drops rapidly,
and the inLtial chlorophyll regenerates already during the
first minute. A later introduction of oxygen does no longer
change the absorption at 670 mA and 520 mp. Figiire 2 shows
the accelerating effect of piperidine and ammonia on the re-
generation of thqinitial chlorophyll and of its photoreduced
forms. Other experiments were conducted with the introductlon
of one of the mentioned bases into the reacting mixture after

Equilibrium -4007 and after atmospheric oxygen had been admitted to it.
In this case the said reaction was markedly accelerated.
Identical experiments with phaeophytine yielded no spectral
changes, which would correspond to the spectrum of the
primary forms (as in Ref 4). When phenylhydrazine was used
for the reduction, the r-th form is produced, which after
the addition of a few drops of piperidine is immediately
transformed into chlorophyll. Thus it is just the bases
which have an effect upon the reaction power of the reduced
pigment forms. There are 4 figures and 7 references, 6 of
which are Soviet.

ABSTRACT: The barteria mentioned in the title contain a green pigment -
bacterioviridin (or chlorobium-chlorophyll) instead of ba:te-
riochlorojhyll, contrary to purple bacteria. It was to be ex-
pected that 'lie great shift of the maximum of bacteric7iridin
nto 'the ~.-r. side (as in the case of bacterio~,hlorophyll)
..an be explained by the aEgregation of pigment mole,:ule6 in
~)Tdered structures. In the present paper the a-utbors invest-

groups the absorption spectra in the red area of the spec-

mpok urements of the kinetics of bleaching and of the absor-
ption spectra. Cblorophyll bleaching after irradiation
with intense red light varied within the limits of 1-30%,

TEXT: The authors describe the formation of active photoproducts in the
photoreduction of bacteriochlorophyll (from Rhodopseudomonas palustris)
and the interaction between these products and electron acceptor molecules
taking part in the biochemical electron transfer of photosynthesis. Bacte-
riochlorophyll was submitted to a final chromatographic purification
(Ref. 4). The photoreactions in pyridine and water were conducted in spe-
cial Tunberg tubes in which measurements with Beckmann and C ~-4 (SF-4)
spectrophotometers were possible. The electron donor typical of bacterial
photosynthesis of Na 2S was used. The solution was evacuated by shaking
for 30-60 sec and exposed to light near the infrared region. As a result,

the absorption maximum of bacteriochlorophyll at 780 m4 dropped rapidly,
while the maximum of the photoreduced form appeared at 66o m4 (Fig. ").
In the dark, this reaction became automatically reverse, and at room tem-
perature bacteriochlorophyll is almost completely regenerated within a
few rr.~n-.ites. Regeneration sets in immediately on exposure to air (Fig. 2)
The ai;,hcrs believe that an extraordinarily active photoreduced form of
pigmen'. and a photooxidized form of electron donor are formed, probablLy
in ac~orlance with the elementary process of X + SH OX + 'SH (X -
molec,,1e of bacteriochlorophyll). They also studied the potential of a
platan-iz electrode during exposure to light of the following types of
pigment in pyridine with an addition of Na 2S: chlorophyll a, bacterio-
ch3&ophyll, and bacterioviridine. The potentials of the three pigments
wer( -ry similar (Fig. 3): During exposureto light, the potential
chanees by approximately 0.1 v in the negative direction. In the dark, the
potential returned to its original value within I - 2 minutes. The authors
assume that all three pigments form electron-active photoreduced products
of the same type. In previous papers (Ref. 7) it was found that photo-
reduced pigments do not accumulate in the ternary system (electron donor -

chlorophyll - eleptron acceptor), since they rapidly react with electron-
acceptor molecules. However, when the reduction of these molecules is
"sensitized", the photoreduced form of the sensitized pigment starts to
accumulate. Hence, the authors conclude that the absence of visible photo-
chemical changes of a sensitized pigment in the ternafy system indicaLes
a rapid reaction of the electron-acceptor molecule with the photoreduced
form of pigment. Using this comparatively sensitive method the authors
tested the action of the following co-factors of photosynthetic phosphory--
lation: Menadione, phenazine metasulfate, and riboflavin (flavin mono-
nucleotide). Hence, they concluded that all of the three last-mentioned
substances can receive electrons from the photoreduced form of chlorophyll.
These experiments on similating systems prove that the above co-factors
take part in the reactions of electron transfer if they are sensitized by
a system of pigments (Ref. 9). The authors recommend the explanation of
such elementary processes with the help of living photosynthesizing
bacteria in which bacteriochlcaopfhyll mainly appears in aggregated and or-
dered forms (Ref. 10) There are 4 figures and 10 references; 8 Soviet
and 2 US.
