  • Publication number: 20240102111
    Abstract: The present invention relates to a molecular marker, a specific primer pair, and an identification method of the high-quality Ganoderma lucidum strain HMGIM-M624. The high-quality Ganoderma lucidum strain HMGIM-M624 was preserved in Guangdong Microbial Culture Collection Center (address: 5th Floor, No. 59 Building of No. 100 Yard, Mid. Xianlie Road, Guangzhou City) with the preservation number of GDMCC No: 60889 on Nov. 7, 2019. The molecular marker is an InDel molecular marker. The high-quality Ganoderma lucidum strain HMGIM-M624 has a base deletion of CATGCTGTA at the 246451th-246460th site of the chromosome sca34. The present invention provides reagents for detecting the molecular marker of the high-quality Ganoderma lucidum strain HMGIM-M624. The reagents can distinguish the high-quality Ganoderma lucidum strain HMGIM-M624 from the other 11 G. lucidum strains for commercial cultivation, thus specifically identifying the high-quality Ganoderma lucidum strain HMGIM-M624.

  • Patent number: 5589046
    Abstract: The present invention relates to a room temperature carbon monoxide gas sensor and a process for preparing the same. The said sensor is prepared by using SnO.sub.2 as base material, Y.sub.2 O.sub.3 La.sub.2 O.sub.3, Cr, Pt black and Al.sub.2 O.sub.3 as additives, after grinding, sintering and aging steps, a sensor which can quantitative and selectively detect carbon monoxide in the atmosphere having a carbon monoxide concentration in the range of 25-600 ppm is obtained. Due to the addition of high purity Cr, the rate of adsorb and desorption of gases of the sensor of the present invention is accelerated, the response and recovery time are less than 10 and 15 seconds respectively.
