| Abstract | Triacylglycerols recovery from wet microalgae is a key aspect of biodiesel production, because of the energetic balance gained from avoiding biomass drying. In order to isolate TAG from Nannochloropsis cells, the possibility to concentrate biomass and to recover TAG in a single step by membrane process was studied. Different polymeric membranes were selected and screened on the basis of adsorption test and permeation flux. Results showed that membrane of regenerated cellulose (RC) with nominal molecular weight cutoff of 100 kDa and 30 kDa gave the best performance. Indeed, permeate flux was stable during ultrafiltration experiment in concentration mode and no severe fouling/cake deposition was observed. Both membranes allowed to recover permeates with high content of triacylglicerols. However, a more purity of the triacylglicerols from the other co-products was only obtained with the 30 kDa RC membrane because the retention of the unwanted proteins was in the range of 89%. |

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.
