Influence of ammonium chloride feeding time and light intensity on the cultivation of Spirulina (Arthrospira) platensis
(JOHN WILEY & SONS INC, 2008)
This study dealt with the influence of both the feeding time and light intensity on the fed-batch culture of the cyanobacterium Spirulina (Arthrospira) platensis using ammonium chloride as a nitrogen source. For this ...
Carbon footprint in commercial cultivation of marine shrimp: a case study in southern Brazil
(Brazilian Journal of Animal Science, 2023)
Management of tillering in the production of flower stems of heliconia cultivated in pots
(2019-09-30)
Potted cultivation of tropical flowers presents good projections for the northeastern region of Brazil; however, it still faces some peculiarities regarding conduction and management. The objective of this study was to ...
Growth and content of Spirulina platensis biomass chlorophyll cultivated at different values of light intensity and temperature using different nitrogen sources
(Sociedade Brasileira de Microbiologia, 2011)
The effects of light intensity and temperature in S. platensis cultivation with potassium nitrate or urea as nitrogen source were investigated, as well as the biomass chlorophyll contents of this cyanobacteria, through the ...
Propriedades físicas e indicador de qualidade de um latossolo vermelho submetido a diferentes sistemas de uso e manejo
(2007-01-01)
The conventional system for soil management and preparation has the intensive mechanization as its basic principle and that changes soil properties, especially physical ones, faster and significantly. This study aimed to ...

Effects of photobioreactor configuration, nitrogen source and light intensity on the fed-batch cultivation of Arthrospira (Spirulina) platensis. Bioenergetic aspects
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
Bioenergetic analysis may be applied in order to predict microbial growth yields, based on the Gibbs energy dissipation and mass conservation principles of the overall growth reaction. The bioenergetics of the photoautotrophic ...
