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

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.

The Thermal Properties and Nutritional Value of Biomass of Oleaginous Yeast Rhodotorula sp. during Glucose Fed-Batch Cultivation in Medium with Waste Nitrogen

“…Lysine limits the value and quality of protein in animal feeding considering the physiology of digestion, so protein rich in Lys may prove to be excellent in the development of feed. The content of lysine in the protein of crustaceans such as M. macrocopa and Simocephalus vétulus was successfully increased by adding red yeast biomass to zooplankton [67]. However, the authors did not reveal the amino acid content of the biomass used.…”

A review on the improvement of cladocera (Moina) nutrition as live food for aquaculture: using valuable plankton fisheries resources

“…M. micrura was reported to contain sufficient crude protein and amino acid concentration to provide basic requirements of larvae and postlarvae feed that are essential to the survival and growth of fry and larval cultivated species (Solomon et al, 2006). Meanwhile, M. mongolica had most essential amino acids less than Artemia and B. plicatilis, but, methionine content in M. mongolica (1.5%) was greater than Artemia (0.9%) and B. plicatilis (0.8%) (Tong et al, 1988;Budhin et al, 2016;Khudyi et al, 2018). Therefore, M. mongolica can serve as a supply medium in terms of methionine levels for fish larvae.…”

Crecimiento poblacional de Macrothrix spinosa alimentada con Chlorella sp.

“…Dentro de la gran diversidad de zooplancton, los cladóceros son considerados como organismos de importancia en acuicultura por el rápido crecimiento poblacional, la variabilidad de tamaño en el desarrollo y por ser presas fáciles para capturar y digerir (Sipaúba-Tavares et al, 2014;Pérez et al, 2015;Luna-Figueroa y Arce, 2017). Además, la composición nutricional de estos organismos es esencial en la primera alimentación de peces; presentan proteína (45-78 %), lípidos (15-40 %), ácidos grasos esenciales (AGE), aminoácidos (aa) y vitaminas, así como, tienen un amplio espectro de enzimas que contribuyen en el óptimo desarrollo de las larvas (Pérez et al, 2015;Luna-Figueroa y Arce, 2017;Khudyi et al, 2018;Cheban et al, 2018;Mellisa et al, 2018).…”
