The intracellular phosphorus and carbon metabolites in the halotolerant alga Dunaliella salina adapted to different salinities were monitored in living cells by 31Pand "3C-nuclear magnetic resonance (NMR) spectroscopy. The 13C-NMR studies showed that the composition of the visible intracellular carbon metabolites other than glycerol is not signiflcantly affected by the salinity of the growth me...

A periodic CO2 dosing strategy for D. salina 19/30 batch culture is proposed. A model of periodic CO2 dosing including dosing time calculation, dosing interval estimation and final chlorophyll yield prediction was established. In experiments, 5% CO2/95% N2 gas was periodically dosed into D. salina culture. Two different gas dosing flow rates were tested. The corresponding dosing time for each f...

The price of aqua feed containing Dunaliella salina meal was calculated. Also, the formulated feed’s protein, lipid, and total carotenoid content were examined. shrimp D. higher than commercial with better protein in feed. This indicated that inclusion microalgae may increase coloration growth shrimp. We recommend using these fish aquaculture necessary investment production.

Background: Green microalgae and Bacillus subtilis have been known to promote productive reproductive performances in ruminant species. The present study aimed improve performance, nutrient digestibility serum metabolites upon supplementation green under heat stress conditions. Methods: Eighty crossbreed beef bulls were allocated into four groups of 20 each. first group served as control, the s...

El objetivo del estudio fue describir la alimentación exógena larvaria y supervivencia de Orestias luteus (Valenciennes, 1846) en condiciones controladas. se realizó el laboratorio cultivo prototipo Fundación Titicaca Perú (FUNTI-PERU) ciudad Puno (Perú). Se utilizó como material biológico, 896 unidades larvas O. donde distribuyó tres tratamientos con repeticiones: 1ro) T1 = 299 unidades, 2do) ...

The objective of our study is to reveal the effects paper cups sold under different brands on aquatic test organisms, Daphnia magna and Artemia salina, which are frequently used in toxicity studies. To this end, survival rates D. A. salina individuals, were kept alive after cooling exposed 20 °C 80 °C, for 24, 48, 72, 96 hours determined. 
 Upon examining results, while no significant decr...

Commercial production of renewable energy feedstocks from microalgae will require reliable and scalable growth systems. Two and one half years of biomass and lipid productivity data were obtained with an industrial-scale outdoor photobioreactor operated in Fort Collins, Colorado (USA). The annualized volumetric growth rates for Nannochloropsis oculata (CCMP 525) and Nannochloropsis salina (CCMP...

BACKGROUND Artemia (Crustacea, Anostraca), also known as brine shrimp, are typical inhabitants of extreme environments. These hypersaline environments vary considerably in their physicochemical composition, and even their climatic conditions and elevation. Several thalassohaline (marine) environments along the Colombian Caribbean coast were surveyed in order to contribute to the knowledge of br...
