“…It would be a fair assumption that microalgae can adapt easily and multiply well in different ecological environment. Li (Li et al, 2014) These effects were in consensus to a previous written report, which proposed that higher biomass productivity and specific growth rate obtained under controlled environment in mixotrophic culture medium than autotrophic culture medium (Feng et al, 2005;Kong et al, 2012). It was found that under mixotrophic conditions, biomass production increased by 3-10 times in case of Chlamydomonas globosa, Chlorella minutissima and Scenedesmus bijuga as compared to that of autotrophic growth conditions .…”

The present study investigates the possibility of integrating an existing industrial large scale biomass production with the treatment of waste water in which a mixture of organic and inorganic rich pollutants was used as a medium. This study suggests that the replacement of a defined medium with a complete mixotrophic medium gives a significant statistical difference in terms of growth parameters i.e. biomass production and specific growth rate.The green microalga C. pyrenoidosa was cultivated under different mixotrophic conditions for evaluation of biomass production. Inorganic defined fog's medium supplemented, with raw dairy wastewater led to 1.37g/L biomass production in comparison to 1.2g/L obtained with pure glucose revealing 14.16% increase. The study also involves the supplementation of raw dairy wastewater as an organic carbon source in an inorganic medium comprising municipal treated water and reverse osmosis (RO) treated wastewater and attained 2.4g/L and 1.6g/L of biomass respectively, as compared to 0.3g/L and 0.16g/L obtained in the wastewaters alone revealing 700% and 900% increase respectively. Mixotrophic regimen cells as analyzed by a 2D Fourier transform infrared (FTIR) spectroscopy for its biochemical content revealed that fog's blended raw dairy waste (RDW) regimen cells had maximum

“…Glucose plays a very important role in the growth and production of yeast cells accumulating lipids. Feng et al (2005) and Xue et al (2008) stated that the addition of glucose could enhance the lipid production by yeast cells. Glucose also acts as the primary initiator as it's a simple carbon source, thus facilitating the utilization of oil waste, which is composed mainly of unsaturated fatty acids that are considered complicated in comparison to the simple glucose.…”

“…Growth Characteristics Figure 1 shows the growth curves of strain NKG400014 in IMK medium and strain JPCC DA0580 in f/2 medium. Cell growth of each strain was monitored by measuring ABS 750 nm [1,11,12]. The cells reached plateau of growth from more than approximately 300 h for NKG400014 and approximately 200 h for JPCC DA0580 (Fig.…”

Marine diatom, strain JPCC DA0580, and marine green microalga strain NKG400014 were selected as high neutral lipid-producers from marine microalgal culture collection toward biodiesel production. These strains were tentatively identified as Navicula sp. and Chlorella sp., respectively, by 18S rDNA analysis. Growth and lipid accumulation conditions of both strains were analyzed by changing nutrient concentrations in growth media and initial illuminance intensity. The highest productivity of fatty acid methyl ester (FAME) reached to 154 mg/L/week for NKG400014 and 185 mg/L/week for JPCC DA0580. Gas chromatography/mass spectrometry analysis indicates that FAME fraction from NKG400014 mainly contained 9-12-15-octadecatrienoate (C18:3) and that from JPCC DA0580 mainly contained methyl palmitate (C16:0) and methyl palmitoleate (C16:1). Furthermore, calorimetric analysis revealed that the energy content of strain was 4,233 +/- 55 kcal/kg (i.e., 15.9 +/- 0.2 MJ/kg) for NKG400014 and 6,423 +/- 139 kcal/mg (i.e., 26.9 +/- 0.6 MJ/kg) for JPCC DA0580, respectively. The value from JPCC DA0580 was equivalent to that of coal. The strains NKG400014 and JPCC DA0580 will become a promising resource that can grow as dominant species in the open ocean toward production of both liquid and solid biofuels.
