April 19,2007Markpatent.Org22 DEPOSITION OF NEW BIOLOGICAL MATERIALS If mew biological materials (microorganism) disclosed in the patent application, then such materials are required to be deposited in any of the International Depositary Authorities (IDA) recognized under the BUDAPEST Treaty on or before filing of the application.
April 19,2007Markpatent.Org23 DEPOSITORY INSTITUTION IN INDIA Microbial Type Culture Collection and Gene Bank (MTCC) - Chandigadh
April 19,2007Markpatent.Org24 PRESENT STATUS OF MTCC It has five sections, namely Actinomycetes Bacteria Fungi Yeast Plasmids
April 19,2007Markpatent.Org25 CLAIMS OF DEPOSITED MATERIAL Title: Medium for the production of betacarotene and other carotenoids from Dunaliella salina (ARL 5) and a strain of Dunaliella salina for production of carotenes using the novel media
April 19,2007Markpatent.Org26 Abstract: A salt solution complex comprising a non conventional salt, namely KCl and conventional salts such as NaCl and MgSO4 in the proportion defined in the specification to generate biomass of higher carotenogenesis in particular Betacarotene and its isomers using Dunaliella salina ARL5 in a single stage of active growth. Dunaliella salina ARL5, a local isolate, has an unique property of having a wide range of pH and temperature tolerance which is beneficial in production terms as it is grown in external conditions (i.e. outdoors).
April 19,2007Markpatent.Org27 Claims 1. A process for culturing Dunaliella salina ARL5 (CCAP 19/36)to produce algae cells having betacarotene and its isomers as well as a a high protein biomass by (a) growing Dunaliella salina ARL5 in an aqueous medium comprising: a salt solution complex comprising KCl, MgSO.sub.4 and NaCl wherein the salt solution complex comprises 0.2M-1M KCl, 0.41M-1.5M MgSO4, 1M-5M NaCl; and (b) recovering carotenes from said algae cells. 2. The process according to claim 1 wherein the salt solution complex comprises 0.35M KCl, 0.6M MgSO4 and 2M NaCl.
April 19,2007Markpatent.Org28 METHOD CLAIM Title: METHOD FOR TRANSCRIPTION OF A DNA SEQUENCE Abstract: A DNA sequence transcribing method involves labeling a DNA fragment with a fluorescent substance, subjecting the labeled fragments to electrophoresis, exposing a gel containing the DNA fragment to light during electrophoresis, and detecting fluorescence generated upon exposure. An image corresponding to a fluorescent image on the gel is transcribed on a recording medium by entering a detecting signal in synchronization with operation of detecting fluorescence on the gel containing the DNA fragment after electrophoresis.

April 19,2007Markpatent.Org30 Claim: 1. A method for transcription of a DNA sequence, comprising the steps of: labeling DNA fragments with a fluorescent sub-stance; subjecting the labeled DNA fragments to gel electrophoresis to cause migration of the fragments in the gel in a first direction; inducing fluorescence of the labeled DNA fragments by excitation with an optical source by linearly scanning the gel along a path extending in a second direction perpendicular to said first direction; detecting the fluorescence generated from the excitation with a photoelectric device arranged in said second direction to produce a signal that varies in intensity along the scanning path in accordance with the fluorescence and outputting the signal; receiving and recording said output signal with an electro-optical transfer device on a photosensitive film as an image of the gel containing the labeled DNA fragments; and moving one of said electro-optical transfer device and said photosensitive film relative to the other at a rate corresponding to a rate of the migration of the DNA fragments within the gel to record a series of said output signals separated from one another by said moving.
