Differentiation between two strains of microalga Parachlorella kessleri using modern spectroscopic method

Botanical studies (2014)

Marwa M. Saleh Д. Н. Маторин B. K. Zayadan D. A. Todorenko Evgenii P Lukashov

The differentiation between wild type of Parachlorella kessleri and its mutant strains PC Mut2, PC Mut4 by using the Multi-functional Plant Efficiency Analyzer (М-РЕА-2) was studied. Mutant algal cells of P. kessleri have been obtained by UV-C during 3 and 10 min respectively.Light-induced kinetics of prompt fluorescence (OJIP transients), delayed fluorescence and modulated reflection at 820 nm (redox transitions of P700 in PSI) showed disturbance of electron transport flow in photosystem II (PSII) and an increase fraction of non-reducing centers of secondary quinone acceptors of electron (QB). In addition, the amplitudes of the fast and slow peak in the kinetics of the delayed light emission and non-photochemical fluorescence quenching ( NPQ) were significantly reduced in mutant cells, indicating low level of the membrane energization of photosynthetic membranes. Changes of photosynthetic reactions of mutants may lead to an increase of the carotenoids content, which protect cells against the light stress.It is suggested to use parameters of induction curves of prompt and delayed fluorescence to characterize mutant algal cells in biotechnological studies.

THE EFFECT OF ISOLATED CYANOBACTERIA ON RICE SEED GERMINATION AND GROWTH

Eurasian Journal of Ecology (2017)

Azadeh Habibi B. K. Zayadan A. Baizhigitova S. Alemyar M. O. Bauyenova

Цианобактериялар топпырақтың құнарлылығына үлкен үлесін қосады. Цианобактерияларөсімдіктердің жоғары деңгейде өсіп дамуына әсер ететіндігі жайлы мәліметтер бар. Әлембойынша цианобактериялардың күріштің өсуіне және топыраққа әсері жайлы жұмыстар өтекөп кездеседі, дегенмен Ауғанстанда бұл зерттеулер өте аз жүргізілген. Бұл зерттеуде Anabaena sp. цианобактериясы Ауғанстанның Бағлан қаласы провинциясының топырағынан бөлініпалынды. Бөлініп алынған Anabaena sp.цианобактериясы құйылған ыдыста, Ауғанстанның үштүрлі күріштері екі сағат бойы ұсталынды. 10 тәуліктен соң, цианобактерия экстрактісіндеұсталынған күріш дәндерінің, өсімдіктің ұзындығы және тамыр ұзындығы, суда ұсталынғандәндермен салыстырғанда, артқаны байқалады. Тәжірибенің келесі кезеңінде күріш дәндеріцианобактериямен байытылған топырақта және сумен байытылған топырақтарда өсірілді. 12тәулік өткен соң цианобактериямен байытылған топырақта өскен өсімдіктің, сумен байытылғантопырақта өскен өсімдіктен ұзындығымен, морфологиясы бойынша әртүрлілігін көрсетеді.Сондықтан, Anabaena sp цианобактериясы Ауғанстанның күріш алқаптарына тиімді биотыңайтқышретінде ұсыныла алады.Түйін сөздер: цианобактерия, инокуляция, биотыңайтқыш, Баглан, Шамарқ, Чашмайшир

Assessment of Biotechnological Potential of Cyanobacteria and Microalgae Strains from IPPAS Culture Collection

Biotekhnologiya (2019)

Roman A. Sidorov Alexander Starikov А. С. Воронков А.С. Медведева Zinaida V. Krivova

As a result of screening of spore-forming bacteria, a B-13186 strain with a wide spectrum of antagonistic activity identified as Brevibacillus laterosporus by the analysis of sequences of variable sites of 16S rRNA was selected. Morphological, cultural and biochemical characteristics of the strain were studied. A distinctive feature of the strain is the presence of a canoe-like inclusion formed in sporangia and attached to the mature spore, as well as the ability to synthesize round-shaped crystalline inclusions. The strain was shown to be active against various species of gram-positive bacteria including A search for strains capable of simultaneously producing high amounts of several biologically valuable compounds and/or having high biomass productivity has been carried out. The growth characteristics and biochemical composition of 12 microalgae and cyanobacteria strains from the IPPAS Collection in the exponential and stationary growth phases were studied. All the strains had high growth rates (doubling time 6-22 h). The strains of Cyanobacterium sp. IPPAS B-1200, Chlorella sp. IPPAS C-1210, Nannochloris sp. IPPAS C-1509, Cyanidium caldarium IPPAS P-510 and Vischeria sp. IPPAS H-242 demonstrated the highest biotechnological potential and can be used for the production of various types of biofuel, pigments, feed and food additives, including those with high content of eicosapentaenoic (20:5 Δ5,8,11,14,17) acid content. microalgae, cyanobacteria, biochemical composition, fatty acids, valuable metabolites, growth characteristics This work was supported by a grant from the Russian Science Foundation [no. 14-14-00904]

Preliminary Phytochemical Analysis and Antioxidant, Antibacterial Activities of Crocus alatavicus from Kazakhstan

Notulae Botanicae Horti Agrobotanici Cluj-Napoca (2015)

Dariya SATYBALDIYEVA Valentina Mursaliyeva Izbassar RAKHIMBAYEV B. K. Zayadan Ramazan Mammadov

Phytochemical analysis of C. alatavicus revealed the presence of phenols, flavonoids, anthocyanins, carotenoids, amino acids and carbohydrates. The flavonoid, amino acids and carotenoid contents were higher in aerial part (1.50%, 7.49% and 9.78mg%, respectively) than in bulb (0.43%, 3.88% and 0.91 mg%, respectively). Total phenolic content (TPC), total antioxidant (TAA), 2.2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging and antibacterial activities of water, methanol, ethanol and dichloromethane extracts from aerial part and bulb were tested. TPC ranged from 13.63 to 72.29 mg gallic acid equivalents (GAE)/g extract. The maximum TAA were observed in ethanol (61.34%) and methanol extracts (46.13%) from aerial part with a high TPC (72.29 and 62.37 mgGAE/g extract, respectively). Ethanol extracts from aerial part and bulb had good scavenger of DPPH radicals (65.5% and 54.08%, respectively) with an IC50 387 and 447 Âµg/ml. Ethanol extract from aerial part was most effective against gram-positive bacterial strains S. aureus, B. subtilis and B. cereus. Biological activities of the extracts were correlated with the TPC. It can be deduced that ethanol and methnol extracts of C. alatavicus contains useful potent bioactive compounds with antioxidant and antimicrobial activities.
