Inducer for quickening haematococcus pluvialis to accumulate astaxanthin and using method for inducer

The invention discloses an inducer for quickening haematococcus pluvialis to accumulate astaxanthin and a using method for the inducer, and relates to the technical field of biological and chemical processes. The inducer provided by the invention is prepared by the following method comprising the following steps: weighing 400g of iodine salts, dissolving the iodine salts with distilled water and keeping constant volume of 1L. The using method for the inducer comprises the following steps: preparing the inducer, adding the inducer and controlling culture water quality. The iodine salts are adopted as the inducer to effectively promote conversion of nutritive cells of the haematococcus pluvialis to akinete, so that the required time can be shortened by about 50 hours, and the accumulation of the astaxanthin in the haematococcus pluvialis is obviously quickened. The using method is simple and suitable for large-scale popularization and application.
