“…The increase of pH during photosynthesis, due to nutrients uptake to consume bi-carbonate; and in the culture media with ideal mixing might optimize microalgae access nutrients and uptake easily the dissolved inorganic carbon (Ramaraj et al, 2015) Results show that the use of inorganic fertilizer and macrophytes with vitamin solutions may be effective as culture media and strongly support the growth of Ankistrodesmus gracilis, since cell density and biochemical composition were similar to or higher than conventional culture medium (CHU 12 ). Further research is necessary to verify the real potential of macrophytes and which plants are more appropriated for cultivation of microalgae.…”

“…High total phosphorus contents in the water media directly affect plants due concentration above 1.8 g.kg -1 and consequently improve microalgae growth. In general, culture media have enough amount of phosphorus for microalgae growth with special reactions associated to cell division (Ramaraj et al, 2015).…”

“…Moreover, these culture media are highly specialized and sometimes difficult to obtain on the local markets. However, efforts have been made to find alternative media for microalgae culture which include macrophytes (Sipaúba-Tavares et al, 2009 and inorganic fertilizers El-Nabris, 2012;Martinez-Córdova et al, 2012;Ramaraj et al, 2015;Sipaúba-Tavares and Pereira, 2008). Macrophytes have dominant and supporting roles in nitrogen and phosphorus recovery.…”

Current study investigated the effectiveness of different macrophytes as culture media for Ankistrodesmus gracilis in laboratory conditions. Significant difference (p < 0.05) was reported in cell density with regard to conventional culture medium (CHU 12 ) and macrophytes culture media. Mean cell density in NPK, Eichhornia crassipes and E. azurea media was higher (p < 0.05) than in conventional culture medium. Chlorophyll-a was higher than 1 g.L (P. cordata medium) and 1.7 g.L -1 (CHU 12 medium) for ammonium, and between 0.8 g.L -1 (CHU 12 medium) and 1.9 g.L -1 (T. domingensis medium) for total phosphorus. Results revealed inorganic fertilizer and macrophytes combined with vitamins may be effective as culture media and strongly supports the growth of Ankistrodesmus gracilis, since cell density and biochemical composition are similar to or higher than conventional culture medium (CHU 12 ). Macrophyte is a tool for aquaculture since biological wastes may be used with nutrients to improve the cultivation of microalgae.Keywords: aquatic plants, culture media, microalgae growth, biochemical composition. Resíduos biológicos de aquicultura como meio de cultura para o cultivo de Ankistrodesmus gracilis (Reinsch) KorshikovResumo O presente estudo investigou a eficácia na utilização de diferentes macrófitas como meio de cultura para Ankistrodesmus gracilis em condições laboratoriais. Foi observada diferença significativa (p < 0,05) entre a densidade celular em relação aos meios de cultura convencional (CHU 12 ) e de macrófitas. Os meios de cultura com Eichhornia crassipes, E. azurea e NPK apresentaram densidade celular maiores (p < 0,05) que o meio de cultura convencional. Os teores de clorofila-a foram superiores a 1 g.L -1 , exceto nos meios de cultura CHU 12 (0.7 ± 0.4 g.L -1 ) e de T. domingensis (0.7 ± 0.3 g.L -1 ). O nitrato diminuiu acentuadamente a partir do 7º dia de experimento. Dentre os nutrientes, amônia e o fósforo total foram os mais elevados nos meios de cultura, variando entre 0.4 g.L -1 (meio de P. cordata) a 1,7 g.L -1 (meio CHU 12 ) para amônia e, entre 0.8 g.L -1 (meio CHU 12 ) e 1,9 gL -1 (meio de T. domingensis) para o fósforo total. Os resultados do presente estudo mostraram que o uso de fertilizantes inorgânicos e macrófitas, combinados com vitaminas, pode ser eficaz como meio de cultura no crescimento de Ankistrodesmus gracilis, uma vez que a densidade celular e a composição bioquímica foram semelhantes ou superiores ao meio de cultura convencional (CHU 12 ). As macrófitas são ferramentas a serem adotadas na aquicultura, desde que os resíduos biológicos podem ser usados como nutrientes para melhorar o cultivo de microalgas.Palavras-chave: plantas aquáticas, meio de cultura, crescimento de microalga, composição bioquímica.

“…Fish may be maintained and developed by live feed through large-scale production of microalgae at high costs, especially with regard to culture media. Several research works have underscored the use of alternative culture media, such as inorganic fertilizers (El-Nabris 2012; Ramaraj et al 2015) or the employment of organic wastes retrieved from aquaculture, such as macrophytes (Sipaúba-Tavares et al 2009, 2018.…”

Microalgae Ankistrodesmus gracilis as feed ingredient for ornamental fish Xiphophorus maculatus

et al. 2019

A trial evaluated the effectiveness of macrophytes, Azolla caroliniana (AAC) and Lemna minor (ALM) as a culture media for microalgae Ankistrodesmus gracilis, and their possible use as feed ingredient for ornamental fish. Water quality in all aquariums was adequate for the growth of Xiphophorus maculatus, whilst pH acidity in inert diet (ID) treatment and high content of P in AAC diet treatment did not interfere in fish development. Growth performance parameters were higher (P \ 0.05) in ALM diet treatment, except condition factor and feed conversion ratio, with similar rates (P [ 0.05) in all diet treatments. Survival was above 75% and total length was similar (P [ 0.05) for ID and AAC diet treatments. Lipid levels ranged between 7 and 11%, and was enough to maintain high survival rates ([ 80%) and weight gain above 0.42 g to mixed diet (AAC and ALM) and 0.27 g to inert diet. Ankistrodesmus gracilis and macrophytes as a culture media are useful as functional ingredients, because biomass may be incorporated with the food supplement for X. maculatus to enhance nutrition quality and to maintain high growth performance. Although A. caroliniana and L. minor may be used with culture media, L. minor provided the best results to microalgae growth biomass and ornamental fish.

“…2,3 In recent years, new drainage standard (GB18918-2002) was put forward by the China government, in which effluents from municipal wastewater treatment plants (WWTPs) should satisfy Class A standard of the first level. However, the large majority of the existing WWTPs could not meet the new standard, so technical renovation towards these WWTPs has become urgent.…”
