   <abstract xml:lang="ru">
    <p>Исследовано влияние интенсивности света и потока углерода на продукцию хлорофилла а и В-фикоэритрина, а также их соотношения в накопительной культуре Porphyridium purpureum. Показано, что с увеличением интенсивности света (в 2 раза) и скорости подачи воздуха (в 2 раза) значение максимальной продуктивности возрастает почти в 2 раза, концентрации хл а – в 1,8 раз, а В-ФЭ – в 1,6 раз. Содержание хлорофилла а и В-фикоэритрина во всех опытных вариантах на 3–4 сутки эксперимента (начало линейной фазы роста) достигло максимального значения. При световом лимитировании содержания хл а и В-ФЭ в биомассе не изменяется, однако при высокой интенсивности света на линейной фазе роста наблюдается уменьшение. Соотношение В-ФЭ/хл а при различном световом и углеродном обеспечении в проведённом эксперименте практически не изменяется и в среднем составляет 12,8.</p>

    <p>The effect of light intensity and carbon flux on the production of chlorophyll a and B-phycoerythrin, as well as their ratios in the batch culture of Porphyridium purpureum, has been studied. It is shown that with an increase in light intensity (by 2 times) and air supply speed (by 2 times), the value of maximum productivity increases by almost 2 times, the concentration of chl a – by 1.8 times, and B-PE – by 1.6 times. The content of chlorophyll a and B-phycoerythrin in all experimental variants on the 3rd – 4th day of the experiment (the beginning of the linear growth phase) reached the maximum value. With light limiting, the content of chl a and B-PE in the biomass does not change, however, with high light intensity, a decrease is observed in the linear growth phase. The ratio of B-PE/chl a with different light and carbon support in the experiment practically does not change and averages 12.8.</p>
