Reducing nutrient requirement using nitrogen-fixing bacteria for microalgae cul...
Melkonyan, Lusine; Ferreira, Alice; Bastos, Carolina R. V.; Figueiredo, Daniel; Lopes da Silva, Teresa; Avetisova, Gayane; Karapetyan, Zh.ABSTRACT: In environments, microalgae have been observed to coexist with bacteria. Different nitrogen-fixing bacteria (NFB) were isolated from Armenian soils and their growth was evaluated in co-cultivation with the microalga Tetradesmus obliquus and cyanobacteria Synechocystis sp. PCC 6803. The most effective mutualistic consortium was T. obliquus-NFB5 (Sphingobacterium sp. L13G8). This resulted an increase in...
Consortium of microalgae/nitrogen-fixing bacteria as a next-generation bioferti...
Gouveia, Luisa; Ferreira, Alice; Bastos, Carolina R. V.; Avetisova, Gayane; Karapetyan, Zh.; Toplaghaltsyan, A.; Melkonyan, LusineABSTRACT: This study aims to provide insights into a new consortium of a microalga, twelve nitrogen-fixing (N-fixing) bacteria and a cyanobacterium. The microalga Tetradesmus obliquus (T), in conjunction with various N-fixing bacteria and the cyanobacterium Synechocystis sp. PCC 6803 (S), the N-fixing bacterium Sphingobacterium sp. L13G8 (5), cultivated in complete Bristol medium and in Bristol-NaNO3 free condi...
From piggery wastewater to wheat using microalgae towards zero waste
Ferreira, Alice; Figueiredo, Daniel; Ferreira, Francisca; Marujo, Ana; Bastos, Carolina R. V.; Martin-Atanes, Guillermo; Ribeiro, BelinaABSTRACT: Microalgae production is still expensive, driving the need to lower costs while strengthening the industry's environmental sustainability. Microalgae are recognized tools for efficient wastewater treatment, offering the recycling of nutrients and water for agriculture, and producing biomass rich in growth-promoting compounds to improve plant productivity and resistance to adverse conditions. The use o...
Algaeculture for agriculture: from past to future
Ferreira, Alice; Bastos, Carolina R. V.; Santos, Cláudia Marques dos; Acién, F. Gabriel; Gouveia, LuisaABSTRACT: The continuous growth of the world population has imposed major challenges on agriculture. Consequently, farmers generalized the overuse of synthetic fertilizers and pesticides to meet the global food demand. Although these products have helped many developing countries increase their crop yield, they have simultaneously resulted in many issues, mainly the decline of soil fertility and degradation of ...

Optimisation of biomass production and nutritional value of two marine diatoms ...
Bastos, Carolina R. V.; Maia, Inês Beatriz; Pereira, Hugo; Navalho, João; Varela, JoãoS. costatum and C. calcitrans are two cosmopolitan high-value centric diatoms, with a rich nutritional profile. The following work optimised the culture medium of <i>S. costatum</i> and <i>C. calcitrans</i> cultures, respectively, in a stepwise process as follows: 2.4 mM and 1.2 mM of silicate, 4 mM of nitrate, 100 µM of phosphate, 20 and 80 µM iron, and 0.5 mL L<sup>−1</sup> of micronutrients. The results that...
