Abstract: The present disclosure belongs to the field of microbial technology, and in particular relates to a microbial agent for promoting root nodule number increase and root nodule nitrogenase activity increase in leguminous crops and use thereof. The microbial agent is compounded from 4 microbes including Bacillus amyloliquefaciens, Brevibacillus laterosporu, Bacillus mucilaginosus Krassilnikov, and Enterobacter ludwigii by separate fermentative cultivation, concentration and mixing. The microbial agent can effectively promote root nodule number increase and root nodule nitrogenase activity increase, promote crop growth, and improve crop yield and product quality.

Abstract: The present disclosure relates to a microbial agent with functions of preventing and controlling aflatoxin and aflatoxigenic strain thereof and promoting yield increase of crops. The microbial agent is compounded from 5 microbes comprising Bacillus amyloliquefaciens, Brevibacillus laterosporu, Bacillus mucilaginosus Krassilnikov, Enterobacter ludwigii and Myroides odoratimimus by separate fermentative cultivation, concentration and mixing. The microbial agent is applied to a field planting stage of crops such as peanuts, which can effectively reduce the abundance and infection probability of toxin-producing strain such as Aspergillus flavus in soil from the source, reduce the risk of aflatoxin pollution of peanuts after production, improve the quality and safety level of peanuts, and at the same time, promote crop growth, enhance the resistance, and improve the full pod rate and yield, and has significant economic, social and ecological benefits.

Abstract: The present invention relates to an early warning method before the occurrence of aflatoxin contamination.

Abstract: A wearable air conditioner includes a shell for being worn around a wearing portion of a user, a fan and a temperature regulating member disposed in the shell. The shell includes a first air passage, a first accommodating chamber, at least one air outlet in communication with the first air passage, and vent holes in communication with the first accommodating chamber. The temperature regulating member is configured for generating heat energy or cold energy. The temperature regulating member is in thermal connection with a sidewall of the first accommodating chamber. An airflow generated by the fan is capable of entering the first air passage and then exiting the shell via the at least air outlet.

Abstract: The present invention relates to an aflatoxin contamination risk warning molecule and use thereof. The steps are as follows: weighing a quantitative sample, extracting the aflatoxin contamination risk warning molecule to obtain a sample extract, and detecting and analyzing the sample extract to obtain a quantitative result of the aflatoxin contamination risk warning molecule; performing modeling with a chemometrics method using the content of one or more of the aflatoxin contamination risk warning molecules as a variable to obtain a classification prediction model, and performing risk assessment on aflatoxin contamination risk of the sample based on the classification prediction model, wherein a warning molecule of an aflatoxin toxigenic strain is one or a combination of more than one of versiconol (VOH), versicolorin B (Ver B), and 5-methoxysterigmatocystin (5-MST).
