Chemické modifikace bilinových barviv
VOMÁČKOVÁ, Hana
This thesis deals with isolation of phycocyanobilin from cyanobacteria Thermosynechococcus elongatus and its purification with TLC. Purified phycocyanobilin was esterified using Fischer esterification method. The esterification method in this thesis was modified by using dichlormethan as solvent. The results were analysed by HPLC method. Pilot experiments dealing with insertion of esterified phycobilins into self-organized aggregates of bacteriochlorophyll c were carried out.
Izolace fykobilinů ze sinice \kur{Synechocystis} a možnost jejich následné esterifikace
KALKUŠ, Milan
This thesis describes phycobilins, their biosynthesis, properties and functions during photosynthesis. Their esters could be used to produce artificial self-assembling lightharvesting antennae. Pigments with similar structures (tetrapyroles) are also described. The experimental part describes the isolation of phycobilins from the cyanobacterium Synechocystis by cleavage with hydrochloric acid, the analysis of obtained pigments by TLC and HPLC methods and esterification of purified phycobilins with butan-1-ol.
