The invention provides a culture of aspergillus terreus in an iron-limited culture medium and application of the culture in organic pollutant treatment, and relates to the field of microorganisms and environmental remediation. According to the method, an iron-limited culture environment is adopted, aspergillus terreus is induced to secrete an iron carrier with metal chelating capacity, an iron source is captured, and therefore an efficient Fenton-like reaction system is constructed, generation of hydroxyl free radicals is promoted, and the method is suitable for in-situ green remediation of refractory organic pollutants.

The application belongs to the technical field of sporogon culture, and particularly relates to a culture method of sporogon of Brychus based on a liquid culture medium, which comprises the following steps: S1, preparing a Brychus sample with mature sporogon; S2, preparing a spore suspension, taking a mature sporangium of the Brychus and taking out spores, and dispersing the spores into distilled water to prepare a spore suspension; and S3, inoculation, inoculating the spore suspension into a culture bottle containing a liquid culture medium, and then culturing the culture bottle after being covered. The application customizes a special liquid culture medium formula according to the physiological characteristics and growth requirements of the sporogon of the Brychus, and matches highly adaptive culture environment parameters, and the two synergistically ensure the smooth culture of the sporogon of the Brychus from the two dimensions of nutrient supply and environment adaptation.

The utility model provides a kind of anti-bending breakage's front suspension instrument, belong to ophthalmology relevant treatment upper eyelid ptosis technical field, including anti-bending breakage suspension line, both ends of the anti-bending breakage suspension line are provided with metal guide needle.The utility model solves the risk of bending point fracture of the existing front suspension instrument when in use, suspension line is implanted into human body for a long time, is easy to cause damage to patient after fracture, reduces the safety of instrument use, and the difficulty of instrument production process is greater, may lead to the shedding of suspension line or the abrasion of suspension line by metal guide needle tail end even fracture in the process of instrument use, reduces the practicability of instrument problem.
