Nostoc es un género de cianobacterias filamentosas con aplicaciones biotecnológicas en nutrición humana, biomedicina, biofertilización y producción comercial de biocombustibles. Sin embargo, su baja tasa de crecimiento en medio líquido por su naturaleza perifítica y su tendencia a formar biofilms, limita su producción a gran escala. Por lo tanto, el objetivo de este estudio fue analizar la producción de biomasa de Nostoc muscorum en un sistema hidropónico modificado. Para ello, se realizaron cultivos de N. muscorum por triplicado, en un sistema hidropónico bajo condiciones semicontroladas de temperatura (29 ± 13°C), intensidad lumínica (32 ± 54 μmol/m2/s) y fotoperiodo (12 horas), durante 23 días en un invernadero. La temperatura, el pH, la conductividad eléctrica y la producción de biomasa seca, fueron monitoreados en días alternados. Los resultados arrojaron que la producción máxima de biomasa seca fue de 0.2276 ± 0.0114 g/m2/día, y la productividad promedio fue de 0.4149 ± 0.0207 g/m2/día. A su vez, la producción máxima de biomasa de N. muscorum se obtuvo el día trece con 0.3185 ± 0.0159 g/m2/día. El análisis estadístico de correlación de variables ambientales no arrojó diferencias significativas, por lo que la temperatura, el pH y la conductividad eléctrica no afectaron la producción de biomasa de N. muscorum. Consecuentemente, el crecimiento algal fue influenciado por la fisiología de la especie. El soporte empleado en el sistema hidropónico permitió la adherencia y el desarrollo de la capa mucilaginosa de la cianobacteria sin requerir períodos de desecación como en los cultivos convencionales. El sistema hidropónico proporcionó un flujo continuo de nutrientes que podría prevenir el ataque de bacterias y hongos oportunistas, generando una alta tasa de crecimiento. De este modo, este sistema hidropónico representa una alternativa viable para la producción de biomasa de N. muscorum en condiciones de invernadero a gran escala.

The present study is about the analysis of sullage collected from Tiruvanchery region, Chennai, Tamil Nadu, India. Sullage is the waste water from households, sinks, bathrooms, kitchen households but except the waste water from toilets. In this project, 6 samples of waste water were collected in 3 different apartments. The apartments are Ruby Grand, Ruby Regency and Green Paradise. The 2 samples of the waste water are the kitchen waste water and washing clothes waste water. Physical, chemical and biological parameters are tested in environmental laboratory. The chemical parameters were tested using titrimetric method. It is found that all samples were safe against pH, Alkalinity, Flouride, Chloride, Iron, Phosphate, and Turbidity which are within the permissible limits of IS3306 (1974)

Based on results of pilot scale research with source-separated black water (BW) and grey water (GW), a new sanitation concept is proposed. BW and GW are both treated in a UASB (-septic tank) for recovery of CH4 gas. Kitchen waste is added to the anaerobic BW treatment for doubling the biogas production. Post-treatment of the effluent is providing recovery of phosphorus and removal of remaining COD and nitrogen. The total energy saving of the new sanitation concept amounts to 200 MJ/year in comparison with conventional sanitation, moreover 0.14 kg P/p/year and 90 litres of potential reusable water are produced

Biodiesel Feedstock

Increment of industrial development and energy demands for transportation and electricity have increased diesel-fuel uses to fulfil global energy needs. Carbon emission as impact of high fossil diesel use which pollutes the air gradually increases green house gases (GHG) and increases the intensity of acid rains. Furthermore, scarcity of fossil-fuels resources has caused high price of diesel-fuel which in turn to have increased the prices of all commodities. Nostoc muscorum is filamentous Cyanobacteria species which lives both terrestrial and freshwater aquatic environment. This strain has good ability in producing high biomass and potential in producing lipid. In where, Nostoc muscorum has potential as biodiesel feedstock alternative of food-plants sources. This study was conducting to evaluate the potential of Nostoc muscorum cultured in BG-II medium as biodiesel feedstock source. Evaluation of the nutrient requirement of Nostoc muscorum cultured in BG-II medium was done through assimilation of nitrate (NaNO3)-phosphate (K2HPO4). Biomass production as growth parameter was measured by weighing the dried biomass for 14 days of culture. Daily lipid production was evaluated by lipid extraction using Soxhlet method. The result showed that Nostoc muscorum cultured in BG-II medium required 644.6795 mg/L of NO3- and 25.1566 mg/L of HPO4- with the highest biomass production 0.21 grams/300 mL. Furthermore, Nostoc muscorum as multicellular Cyanobacteria could grow well in BG-II medium at SGR 0.0964 μ/day. Lipid production of Nostoc muscorum during cultivation in BG-II for 14 days decreased day by day. The highest lipid production was reached up in day 4th of culture that was 9.53 mg/g. Based on this study, Nostoc muscorum has good potential as biodiesel feedstock through producing high biomass in BG-II medium.
