“…Uptake of these inorganic forms of carbon also has the potential to increase the pH within the cultures (Hansen, 2002). Oxygen (O 2 ) is a product of photosynthesis and levels above atmospheric O 2 levels (0.2247 mol O 2 m -3 ) can inhibit photosynthesis in a number of microalgal species, even when the CO 2 levels remain elevated (Aiba, 1982). Furthermore, elevated levels of O 2 coupled with high irradiance can lead to photo-oxidation (Richmond, 1990;Camacho Rubio et al, 1999).…”

Microalgae are unicellular photosynthetic organisms that inhabit diverse ecological habitats ranging from freshwater and brackish water to seawater and wastewater. They are also especially equipped to thrive in extreme temperatures and pH conditions. Decades of research have highlighted their potential as sources of biofuels, foods, feeds and high-value bio-actives. However, industrial-scale cultivation of microalgae is still not being carried out to its full potential. This review aims to shed light on the potential of microalgal-derived food, feed and fuel in developing countries and to what extent microalgae could be applied to sustainable development efforts with a special focus on Kenya. The Kenyan government has set out a development policy termed 'Kenya Vision 2030' that aims to transform the nation into a newly industrialised country with a high quality of life for all its people by the year 2030. Here we show that, not only does Kenya lie in an optimal geographical region for microalgal cultivation, but that microalgae has the capability to fulfil some of the 'Kenya Vision 2030' goals.

“…Note, however, that the costs of closed systems are substantially higher than their open pond counterparts [54]. A variety of closed photobioreactors have been tested (or at least proposed) for industrial microalgal biomass production [64,65], but engineering and economic analyses of such reactors still lag behind the open ponds [66][67][68][69][70].…”

“…Recently, microalgal photosynthesis was considered as an effective means to reduce the emission of carbon dioxide, a major greenhouse gas, to the atmosphere (Benemann, 1997;Karube et al, 1992;Yun and Park, 1997a,b;Yun et al, 1996). As the potential of microalgal mass culture increases, kinetic modeling of microalgal photosynthesis and/or growth has become of significant importance because an accurate model is a prerequisite for designing an efficient photobioreactor, predicting process performance, and optimizing operating conditions (Aiba, 1982;Ever, 1991;Rabe and Benoit, 1962). In addition, the mechanistic modeling approach can be useful for confirming or rejecting the hypotheses on mechanisms underlying the models.…”

Light-dependent photosynthesis of Chlorella vulgaris was investigated by using a novel photosynthesis measurement system that could cover wide ranges of incident light and cell density and reproduce accurate readings. Various photosynthesis models, which have been reported elsewhere, were classified and/or reformulated based upon the underlying hypotheses of the light dependence of the algal photosynthesis. Four types of models were derived, which contained distinct light-related variables such as the average or local photon flux density (APFD or LPFD) and the average or local photon absorption rate (APAR or LPAR). According to our experimental results, the LPFD and LPAR models could predict the experimental data more accurately although the APFD and APAR models have been widely used for the kinetic study of microalgal photosynthesis.
