“…It has been reported by many researchers that nutrient limitation usually nitrogen in the growth medium is responsible for lipid accumulation in microalgal cell (Cheng et al,2012;Karemore et al, 2013;Klok et al, 2013; PeerJ 2013; Liu et al, 2008;Pedro et al, 2013;Xin et al, 2010;Zhang et al, 2014).…”

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

“…The more magnesium content in the medium, the higher the rate of photosynthesis in the cells was. Magnesium also acts as an activator for ribulosebisphosphate carboxylase and phosphoenolpyruvate carboxylase [2], two essential enzymes in carbon fixation during photosynthesis. Magnesium contained in the addition of molasses will stimulate metabolic activity, so that microalgae can grow better and produce more chlorophyll [13].…”

“…The mixotrophic system allows the integration of both components of photosynthesis and heterotrophic during the diurnal cycle. This system will reduce the impact of shortage of biomass for dark respiration and lower the amount of organic substances which are used during cell growth [2].…”

Abstract. Globally, there is growing interest in microalgae as production organisms. Microalgae contain lipids (oil), proteins and carbohydrates (sugars), and, especially marine algae have been used as food and feed for centuries. Recently, production cost reduction related to the supply of growth nutrients is necessary to make it profitable. Therefore, utilization of molasses, a byproduct of sugar production, as the natural carbon, macronutrients, and micronutrients sources can be helpful. The analysis showed that the content of sucrose, glucose, fructose, potassium, zinc, and magnesium was 68.4% w/w, 18.5% w/w, and 13.1% w/w, 5.5% w/w, 3.91 ppm, and 1,370 ppm respectively. This work aimed to determine the effect of molasses addition to the physio-chemical properties of multi-culture species of microalgae isolated from southern Java coastal region in Indonesia grown under mixotrophic culture. The cultivation in this work used medium which was selfformulated by the authors consisting of NaNO3 (5 mL/L), H3BO3 (1 mL/L), EDTA (1 mL/L), N2H2PO4 (5 mL/L), FeSO4 (1 mL/L), MgSO4 (1 mL/L), NaCl (1 mL/L), micronutrients (1 mL/L), vitamin B1 (1 mL/L), and vitamin B12 (1 mL/L) in 500 mL of water. The medium will be treated to have molasses concentration of 0. 05% v/v, 0.15% v/v, 0.25% v/v, 0.35% v/v, and 0.45% v/v.

“…Graba et al [16] used a simplified form of the model introduced by Uehlinger et al [31] and determined that the role of local hydrodynamics in the catastrophic detachment process is likely associated with the magnitude of floods. Recently, response surface methodology (RSM) has attracted significant attention as a statistical tool to determine the optimal conditions for multiple variables [32][33][34]. RSM has many advantages compared to other methods; for instance, it is more economical and less time-consuming [35][36][37].…”

Artificial streams were set up to test the relationship between near-bed water velocity and periphyton growth. Periphyton community samples collected from a Japanese stream were incubated for 44 days under a light intensity of 252 ± 72 µmol·photons/m 2 ·s, a temperature of 20-25 • C, and three near-bed water velocity classes: low (<17.9 cm/s), moderate (17.9-32.8 cm/s), and high (>32.8 cm/s). A logistic model was applied to estimate the maximum net growth rate (µ max ) and carrying capacity (B max ). A response surface method was also applied to estimate chlorophyll a (Chl-a) and ash-free dry mass (AFDM) with respect to the independent variables (i.e., time and water velocity). We detected both the highest µ max (1.99 d −1 ) and highest B max (7.01 mg/m 2 ) for Chl-a at the moderate water velocity. For AFDM, we observed the highest µ max (0.57 d −1 ) and B max (1.47 g/m 2 ) at the low and moderate velocity classes, respectively. The total algae density in the region of moderate velocity at the end of the experiment was 6.47 × 10 3 cells/cm 2 , corresponding to levels 1.7 and 1.3 times higher than those at lower and higher velocities, respectively. Our findings indicated that the moderate near-bed water velocity provided favorable conditions for algal growth and corresponding biomass accumulation.
