“…Our study showed that the activity of carbonic anhydrase of A. fertilissima was significantly higher under ambient C 0 2 than the carbonic anhydrase reported in Nostoc calcicola and Anabaena sp. by Jaiswal et al (2005) and Chlorellapyrenoidosa and Chlamydomonas reinhardtii by Xia and Gao (2005) under elevated COz, suggesting that susceptibility of carbonic anhydrase to higher C 0 2 levels varies from organism to organism.…”

We studied the growth of Anabaena fertilissima under graded C 0 2 and temperature conditions to assess its suitability as a C02 scavenger for carbon recycling. A. fertilissima reached maximum growth at 6% C02, but growth declined above this C 0 2 level; yet, at no C 0 2 concentration growth was less than that at ambient C02. High temperature (>30°C) reduced growth of the cyanobacterium, but presence of elevated (6%) C02 lessened the intensity of that reduced growth. High temperature also reduced biomass, pigments, total protein, and nitrogen fixation, but elevated C 0 2 significantly moderated this negative effect. Elevated C02 reduced I4co2 uptake by 50% at 30°C and >44% at higher temperatures compared to uptake at ambient C 0 2 at 30°C. Similarly, carbonic anhydrase activity also showed inhibition at high C02.

“…Cyanobacteria or blue-green algae (BGA) constitute the largest group of photosynthetic prokaryotes with a wider spread and huge diversity globally, mostly in the terrestrial and aquatic ecosystems [12][13][14][15]. Their presence in different ecosystems, particularly terrestrial, makes them an essential part of the soil microflora with the potential of increasing the productivity of soil either directly or indirectly [16][17][18].…”

Cyanobacteria are found to be renewable and sustainable additives for growth improvement in crops. Extracts and biomass of three nitrogen-fixing cyanobacteria namely, Roholtiella sp. (QUCCCM97), Nostoc ellipsosporum (QUCCCM99), and Desmonostoc danxiaense (QUCCCM112) isolated from Qatar desert environment were tested for their ability to enhance the growth of bell pepper (Capsicum annuum L.) seedlings. Soilless cultivation experiments were carried out by applying the biomass and the aqueous extract of the three cyanobacteria separately. Seedlings were transplanted to Hoagland’s solution under regulated conditions. In total, 2, 4, and 6 mL L−1 of the three microalgae extract as well as 1 and 2 mg L−1 of the three microalgae biomasses (as biofertilizer) were added to the Hoagland solution. An assessment of seedling growth parameters such as shoot length, root length, fresh weight, dry weight, spad index, number of leaves per plant, and growth rate was performed. However, among the different doses and concentrations of investigated QUCCCM97, 99, and 112, our findings revealed that shoot length (cm), root length (cm), fresh weight (g), the number of leaves per plant, and growth rate were positively affected and significantly increased at maximum dose/concentration compared to control plants. With QUCCCM97, shoot length, root length, fresh weight, the number of leaves, and the growth rate increased by 17.5%, 40.3%, 26.0%, 21.6%, and 22.8%, respectively, compared to the control. Additionally, with QUCCCM99, the same parameters increased by 12.3%, 25.3%, 15.1%, 9.3%, 51.8%, respectively. While in presence of QUCCCM112, they increased by 8.7%, 30.1%, 15.6%, 5.4%, 48.6%, respectively. Our results demonstrated that extracts and biomass of cyanobacteria strains investigated here, and particularly Roholtiella sp. (Nostocales), have an enhancement potential of the seedling growth and could be used in modern agriculture to enhance productivity under the soilless system and ensure sustainability.

“…In tobacco plants, the CA activity of high concentration CO2-grown cells was observed to be higher until day 4, after which the activity was lower than that of the ambient CO2-grown cells. Jaiswal et al (2005) found increasing CA activity in two cyanobacteria, Anabaena sp. (ARM 629) and Nostoc calcicola, which were transferred from a higher CO2 concentration (2-25%) to ambient CO2 concentration.…”

We have identified an efficient filamentous marine cyanobacterium, Phormidium valderianum BDU 20041, which was adaptive to different concentrations of CO2. In our study, P. valderianum BDU 20041 was grown under ambient (0.04) and elevated (2, 3, 4, 5, 10, and 15%) CO2 concentration. Its optimal growth occurred at 3% CO2 supply. P. valderianum displayed similar carbon fixation activities through Rubisco, phosphoenolpyruvate carboxylase (PEPC), carbonic anhydrase, and malate dehydrogenase. The activity of Rubisco, the primary carbon-fixing enzyme, was found to be approximately 80% higher in P. valderianum grown under 4% CO2 than under ambient air. This was substantiated by Western blot. The nitrogen-assimilating enzymes shared a similar trend at higher CO2 concentrations. Our study is one of the few reports that examined the activities of CO2-fixing and nitrogen-assimilating enzymes together. Due to the active PEPC, this cyanobacterium was found to have active C3 and C4 enzymes that promoted higher CO2 fixation and cellular growth. Thus, it may be an efficient organism for biotechnological exploitation.
