Nutrient and media recycling in heterotrophic microalgae cultures
Applied Microbiology and Biotechnology, 2015In order for microalgae-based processes to reach commercial production for biofuels and high-value products such as omega-3 fatty acids, it is necessary that economic feasibility be demonstrated at the industrial scale. Therefore, process optimization is critical to ensure that the maximum yield can be achieved from the most efficient use of resources.

Autoclave all nutrient media at 121°C for 15 min. Media which contain 1–2% agar are poured into plastic petri dishes in 20 ml portions (agar plates). Soft agar, immediately after autoclaving, is distributed in 3 ml portions into small test tubes and kept molten in a 47°C water bath. If a medium is to be supplemented with a material whose heat stability

[Nutrient media for the biosynthesis of eremomycin].
Antibiotiki i khimioterapiia = Antibiotics and chemoterapy [sic], 1989The composition of the medium for biosynthesis of eremomycin was optimized with mathematical design of the experiment. Optimal concentrations of the medium components were determined with the method of orthogonal latin squares. The levels of eremomycin production on the medium were 60-89 per cent higher than those on the initial medium.

Relevance of nutrient media composition for hydrogen production in Chlamydomonas
Photosynthesis Research, 2015Microalgae are capable of biological H2 photoproduction from water, solar energy, and a variety of organic substrates. Acclimation responses to different nutrient regimes finely control photosynthetic activity and can influence H2 production. Hence, nutrient stresses are an interesting scenario to study H2 production in photosynthetic organisms.

[Nutrient media for fermenting Actinomyces].
Laboratornoe delo, 1990Fitness of various commercial nutrient media, manufactured in the USSR, for isolation and cultivation of fermentation-producing actinomyces was under study. The media were tested in two stages. Reference and newly isolated actinomyces cultures were examined at stage 1, clinical material at stage 2.

Preparation and composition of nutrient media
1987The in vitro growth and development of a plant is determined by a number of complex factors: 1. The genetic make-up of the plant. 2. Nutrients: water, macro- and micro-elements, and sugars. 3. Physical growth factors: light, temperature, pH, O2 and CO2 concentrations. 4.

[The determination of Escherichia virulence on nutrient media].
Mikrobiologicheskii zhurnal, 1990The virulence of 250 pathogenic Escherichia strains secreted from humans and from various environmental objects has been studied on nutrient media with stains, ram erythrocytes and in hemagglutination reactions. The highest percentage of strain virulence is revealed when using crystal violet and in the blood agar (44.0 and 27.2%, respectively ...

[Production of pesticins on synthetic nutrient media].
Antibiotiki, 1982It was found that 96.2 per cent of the plague microbe cultures studied had a capacity to produce pesticin I on solid and liquid minimum synthetic nutrient media providing growth of the cultures. No pesticin III was detected in the spheroplasts of plague microbes, when they were grown on the synthetic nutrient medium, while on the complete nutrient ...
