| Abstract | DNA homology studies were performed on various strains of Arthrobacter and related organisms with peptidoglycans (mureins) of the A3 and A4 variations. Homology values above 20% show strains with the A4 variation to form a coherent group, which is here designated as the 'nicotianae' group of organisms. Members of this group show homology values of lower than 20% with strains of the 'globiformis' group (Arthrobacter globiformis and relatives), having a A3 peptidoglycan variation. However, the phylogenetic analysis of one representative of the 'nicotianae' group by 16S rRNA cataloguing and the comparison of the data with those of A. globiformis, A. oxydans and A. atrocyaneus reveals a close relationship between members of the 'nicotianae' and 'globiformis' groups. These data indicate that the genus Arthrobacter contains two nuclei whose members can be distinguished from each other by the peptidoglycan type and the menaquinone composition. Strains forming the 'nicotianae' group fell into several subgroups which are separated by DNA homology values of less than 50%, indicating the presence of at least 5 genospecies. The genetic data, supported by results of biochemical and physiological studies, provide sufficient grounds to allot the strain Cory nebacterium liquefaciens ATCC 14929 to Arthrobacter nicotianae, for the reclassification of Brevibacterium protophormiae as Arthrobacter protophormiae comb. nov. and for the description of two new species, Arthrobacter sulfureus sp. nov. and Arthrobacter uratoxydans sp. nov. |

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.
