Microalgae problem

A few words should be said about the existence of PMT-based instruments that are developed to solve specific problems in chemi- or bioluminescence. For instance, marine laboratories have developed and improved over time a range of so-called bathyphotometers for hydrobiophysical measurements (microalgae, zooplankton in the surface waters of the sea) [7]. 

Although this model appeared to work well in calculating decay constants for predominantly labile sources of organic matter such as macro- and microalgae, there were problems with more refractory sources of detrims such as Spartina (Rice and Hanson, 1984). To better describe the decay dynamics of refractory detritus, which generally contain both labile and refractory biochemical components, the following two-G model was developed by Rice and Hanson (1984) ... 

The increase of CO2 in the atmosphere has been considered to be one of the causes of global warming. The amount of CO2 exhausted from the thermal power stations of electric power companies has reached approximately one fourth of the total amount of CO2 exhausted in Japan. Therefore, as one of the measures to cope with this problem, technologies to fix CO2 using the photosynthetic ability of the microalga have been studied [2], The establishment of the utilization technology of CO2 which is fixed by microalga is also... 

The synthesis of microbial fat by bacteria is often ignored because the average fat concentration in dry biomass does not exceed 10%. However, there are strains of Arthrobacter sp., Mycobacterium, and Corynebacterium that are able to accumulate from 30 to 80% lipids in dry matter. Unfortunately, there are other problems related to low growth rates and yields of bacteria, lipid extraction, and the possible allergeiucity and toxicity of the resulting lipids. Microalgae (e.g., Botryococcus braunii and Chlorella pyrenoidosa) serve as attractive sources of PEFA. Dry biomass fat can amount to as much as 85% (Kay, 1991). Moreover, microalgae are a very...

A wide range of microorganisms have been used as biocatalysts. Bacteria dominate but cyanobacteria, microfungi, protozoa, and microalgae have all been successfully used in biosensors. Whilst living cells have many benefits as biocatalysts they also pose unique problems and these need to be successfully overcome before microbial-based sensors can become commercially successful. Six major benefits can be identified ...
