Differences in Nutritional Value and Amino Acid Composition of <i>Moina macrocopa</i> (Straus) Using Yeast <i>Saccharomyces cerevisiae</i> and <i>Rhodotorula glutinis</i> as Fodder Substrates

Abstract

The nutritional composition and amino acid profile of Moina macrocopa were studied using different types of yeast (Saccharomyces cerevisiae and Rhodotorula glutinis) as fodder substrates. The effective accumulation of carotenoids in Moina macrocopa during R. glutinis yeast application was not accompanied by deterioration in the nutritional value of zooplankton. The content of total proteins and total lipids in Moina grown on S. cerevisiae and R. glutinis was not significantly different. However, the use of R. glutinis in the cultivation of M. macrocopa led to the change in the ratio of proteinogenic amino acids in the studied cladocerans. In particular, the share of methionine, leucine and isoleucine significantly increased. It allowed to enhance the quality of protein in the fodder zooplankton, that is especially important in the feeding of fish fry.

“…Besides, Rhodotorula has been used to increase the nutritional value of live food in aquaculture, such as cladocerans (Khudyi et al 2018), also are capable of using many compounds such as carbon sources, glucose, galactose, sucrose, maltose, ethanol, glycerol, and hexadecane (Navarrete & Tovar-Ramírez 2014, Kot et al 2016, Gerelmaa et al 2018. It is a good source of lipids, enzymes, vitamins, MOS, and carotenoids (β-carotene, torulene, and torularhodin) (Bhosale 2004, Kot et al 2016, Gerelmaa et al 2018.…”

Comparative analysis of nutritional profiles of Moina macrocopa cultured in different media: An investigation into the effects of culture media on aquatic organism nutrition

“…varies considerably on the availability of food and the protein contents remain at an average of 50% on a dry weight basis, which slightly differs from than present findings but quietly identical to Creswell (1993) analyzed 59.12% crude protein fed with poultry manure. Oleksii et al, (2018) [28] worked on the differences in the nutritional value of M. macrocopa by using Saccharomyces cerevisiae and Rhodotorula glutinis and obtained 51.04±4.56% and 55.51±2.41% crude protein, respectively. These findings are almost similar with mixed and cattle manure treated M. macrocopa but lower in of Chlorella, Spirulina, and Baker's yeast treated M. macrocopa of this study.…”

Adicionalmente, exhiben un amplio espectro de enzimas (proteasas, lipasas, amilasas, peptidasas, entre otras) y aportan entre un 70 a 80 % de la actividad total enzimática en el tracto digestivo de larvas cuando son consumidos (Gao et al, 2017).…”
