| Abstract | The present study reviews the options of cultivating the green alga, Chlorella emersonii, under photoautotrophic conditions with flue gas derived from a cement plant. It was conducted in the Lafarge Perlmooser plant in Retznei, Austria, where stone coal and various surrogate fuels such as used tyres, plastics and meat-and-bone meal are incinerated for heating limestone. During 30 days of cultivation, flue gas had no visible adverse effects compared to the controls grown with pure CO$_{2}$. The semi-continuous cultivation with media recycling was performed in 5.5-L pH-stat photobioreactors. The essay using CO$_{2}$ from flue gas yielded a total of 2.00 g L$^{−1}$ microalgal dry mass and a CO$_{2}$ fixation of 3.25 g L$^{−1}$. In the control, a total of 2.06 g L$^{−1}$ dry mass was produced and 3.38 g L$^{−1}$ CO$_{2}$ was fixed. Mean growth rates were between 0.10 day$^{−1}$ (control) and 0.13 day$^{−1}$ (flue gas). No accumulation of flue gas residues was detected in the culture medium. At the end of the experiment, however, the concentration of lead was three times higher in algal biomass compared to the control, indicating that cultures aerated with this type of flue gas should not be used as food supplements or animal feed. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
