ОСОБЕННОСТИ ХРАНЕНИЯ ВОДНОГО ЭКСТРАКТА R-ФИКОЭРИТРИНА
Provedor de dados: 13
Autores: Береговая, Н. М.
Рассматриваются различные способы хранения водного раствора R-фикоэритрина, пигмента – фикобилипротеина макроводоросли Gelidium latifolium (Grev.) Born. et Thur., являющейся биотехнологическим объектом. Выявлено, что наилучшими условиями хранения пигмента являются: температура 4 – 5 ºС, отсутствие света, исходная концентрация гелидиума 10 – 40 мг · мл -1, конечная концентрация этанола как консерванта 20 – 40 %. http://biotex.ibss.org.ua/

During the Echolag cruise (13 February-8 March 2007), the effect of 16-30 knot trade winds on abundance, community structure and dynamics of phytoplankton was investigated in the southern part of the New Caledonian coral reefs and surrounding oceanic waters. In this area, the coral reefs form two horn-like structures (hereinafter referred to as 'horn reefs'), oriented south-east, and separated by a relatively deep valley. Three repeated samplings at one week intervals of a 32 station array showed that trade winds induce surface water cooling and significant enrichment of mid- and bottom waters above the reef shelf. This enrichment appeared as the result of a general rise of the oceanic thermocline and nitracline due to the combination of trade winds and...

In the present study, microwave-assisted extraction was first employed to extract the phycobiliproteins of Porphyridium purpureum (Pp). Freeze-dried Pp cells were subjected to microwave-assisted extraction (MAE) to extract phycoerythin (PE), phycocyanin (PC), and allophycocyanin (APC). MAE combined reproducibility and high extraction yields and allowed a 180- to 1,080-fold reduction of the extraction time compared to a conventional soaking process. The maximal PE extraction yield was obtained after 10-s MAE at 40 A degrees C, and PE was thermally damaged at temperatures higher than 40 A degrees C. In contrast, a flash irradiation for 10 s at 100 A degrees C was the best process to efficiently extract PC and APC, as it combined a high temperature necessary...
