Open the CIPO recordAbstract From the Canadian patent
Haloalkaliphilic bacteria have been isolated from samples of soil, water, sediment, trona (NaHCO3.Na2CO3.2H2O) and a number of other sources obtained from in and around hypersaline soda lakes. These bacteria have been analyzed according to the principles of numerical taxonomy with respect to each other; as well as to other known haloalkaliphilic bacteria. In addition these, bacteria are further circumscribed by chemotaxonomic analysis. The bacteria produce various alkali- and salt-tolerant enzymes which may be used in various industrial processes requiring such enzymatic activity in a high pH, saline environment.

Why it's free to use
- Filed October 30, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 30, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 30, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
