  • Method of quickly drying a fresh sample and method of preserving a dried body
    Patent number: 6508013
    Abstract: There are provided a method of drying a fresh sample in a short period of time, a method of fabricating a pressed flower or specimen which retains a beautiful color, and a method of fabricating tea or herb tea which retains a natural beautiful color and scent. The method of quickly drying a fresh sample is characterized in comprising the steps of covering an outer surface of a fresh sample with a moisture absorbent porous flexible sheet, surrounding the periphery of the moisture absorbent porous flexible sheet with moisture absorbent granular bodies in an amount capable of absorbing all moisture contained in the fresh sample, bringing the outer surface of the fresh sample, the moisture absorbent porous flexible sheet and the moisture absorbent granular bodies into intimate contact with one another, and irradiating the fresh sample, the moisture absorbent porous flexible sheet and the moisture absorbent granular bodies with a microwave, then cooling them.

  • Microorganisms, microbial symbionts, their culture methods, and methods for treating manganese-containing water using them
    Patent number: 6350605
    Abstract: This invention relates to a novel microorganism capable of oxidizing manganese such as the genus Cedecea bacterium GSJ/MITA24A/ASHO-RO/1, the genus Aeromonas bacterium GSJ/MITA24B/ASHO-RO/2, or the genus Shewanella bacterium GSJ/MITA24C/ASHO-RO/3; to a method for removing manganese from water containing manganese, which comprises contacting the water containing manganese with a microbial symbiont of algae and one or more microorganisms capable of oxidizing manganese to oxidize and precipitate the manganese, thereby removing the manganese from the water; and to a method of recycling the recovered manganese.
