| Abstract | The yeast Candida utilis (also referred to as Torula) is used as a whole-cell food additive and as a recombinant host for production of intracellular molecules. Here, we report recombinant C. utilis strains secreting significant amounts of Candida antarctica lipase B (CalB). Native and heterologous secretion signals led to secretion of CalB into the growth medium; CalB was enzymatically active and it carried a short N-glycosyl chain lacking extensive mannosylation. Furthermore, CalB fusions to the C. utilis Gas1 cell wall protein led to effective surface display of enzymatically active CalB and of β-galactosidase. Secretory production in C. utilis was achieved using a novel set of expression vectors containing sat1 conferring nourseothricin resistance, which could be transformed into C. utilis, Pichia jadinii, Candida albicans, and Saccharomyces cerevisiae; C. utilis promoters including the constitutive TDH3 and the highly xylose-inducible GXS1 promoters allowed efficient gene expression. These results establish C. utilis as a promising host for the secretory production of proteins. |

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.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
