IN VITRO ACTIVITY OF EXTRACTS OF FIVE MEDICINAL PLANT SPECIES ON PLANT PATHOGENIC FUNGI

《农业科学与工程前沿（英文）》 2021年第8卷第4期页码 635-644 doi: 10.15302/J-FASE -2020343

摘要：

The antifungal effectiveness of extracts of five medicinal plant species was determined. The inhibitory activity of extracts of Eucalyptus tereticornis, Xanthium sibiricum, Artemisia argyi, Tupistra chinensis and Pyrola calliantha were evaluated against the mycelial growth of the plant pathogenic fungi Aspergillus niger, Botrytis cinerea, Penicillium digitatum, P. expansum, P. italicumand Rhizopus stolonifer. All plant extracts were prepared at 60°C using solvents (either water, 50% ethanol (v/v), 95% ethanol (v/v), ethyl acetate or petroleum ether). Fungicidal effects of all plants tested were confirmed. Different extracts from the same plant species gave different degrees of inhibition. All aqueous extracts had weak or no activity on all fungi tested. Ethyl acetate and 95% ethanol extracts from T. chinensis rhizomes gave greater inhibition and a broader spectrum inhibition than the other extracts. T. chinensis may have potential as a new natural fungicide and may be used for the preservation of agricultural and forestry products such as fruits and vegetables.

Epidemiology of fungal infections in China

摘要：

With the increasing number of immunocompromised hosts, the epidemiological characteristics of fungal infections have undergone enormous changes worldwide, including in China. In this paper, we reviewed the existing data on mycosis across China to summarize available epidemiological profiles. We found that the general incidence of superficial fungal infections in China has been stable, but the incidence of tinea capitis has decreased and the transmission route has changed. By contrast, the overall incidence of invasive fungal infections has continued to rise. The occurrence of candidemia caused by species other than and including some uncommon species has increased recently in China. Infections caused by have also propagated in recent years, particularly with the emergence of azole-resistant . An increasing trend of cryptococcosis has been noted in China, with var. ST 5 genotype isolates as the predominant pathogen. Retrospective studies have suggested that the epidemiological characteristics of pneumonia in China may be similar to those in other developing countries. Endemic fungal infections, such as sporotrichosis in Northeastern China, must arouse research, diagnostic, and treatment vigilance. Currently, the epidemiological data on mycosis in China are variable and fragmentary. Thus, a nationwide epidemiological research on fungal infections in China is an important need for improving the country’s health.

Microbial remediation of aromatics-contaminated soil

Ying Xu, Ning-Yi Zhou

《环境科学与工程前沿（英文）》 2017年第11卷第2期 doi: 10.1007/s11783-017-0894-x

摘要： Aromatics-contaminated soils were successfully remediated with adding single strains. Bacterial or fungal consortia were successfully used in the cases of bioaugmentation. Microbes combined with chemical or biological factors increase remediation efficiency. The environmental factors had appreciable impacts on the bioaugmentation. Aromatics-contaminated soil is of particular environmental concern as it exhibits carcinogenic and mutagenic properties. Bioremediation, a biological approach for the removal of soil contaminants, has several advantages over traditional soil remediation methodologies including high efficiency, complete pollutant removal, low expense and limited or no secondary pollution. Bioaugmentation, defined as the introduction of specific competent strains or consortia of microorganisms, is a widely applied bioremediation technology for soil remediation. In this review, it is concluded which several successful studies of bioaugmentation of aromatics-contaminated soil by single strains or mixed consortia. In recent decades, a number of reports have been published on the metabolic machinery of aromatics degradation by microorganisms and their capacity to adapt to aromatics-contaminated environments. Thus, microorganisms are major players in site remediation. The bioremediation/bioaugmentation process relies on the immense metabolic capacities of microbes for transformation of aromatic pollutants into essentially harmless or, at least, less toxic compounds. Aromatics-contaminated soils are successfully remediated with adding not only single strains but also bacterial or fungal consortia. Furthermore several novel approaches, which microbes combined with physical, chemical or biological factors, increase remediation efficiency of aromatics-contaminated soil. Meanwhile, the environmental factors also have appreciable impacts on the bioaugmentation process. The biostatistics method is recommended for analysis of the effects of bioaugmentation treatments.

《中国工程科学》 2019年第21卷第4期页码 105-110 doi: 10.15302/J-SSCAE-2019.04.009

摘要：

农业技术落后与缺乏严重阻碍了非洲农业的发展，我国作为农耕历史文化悠久以及负责任大国，通过输出实用生产技术实现中非合作是值得思考的问题。企业是中国农业“走出去”的主体，本文以吉林省海外农业投资开发集团有限公司为例，发现基于我国食用菌产业实力雄厚、优化大国形象的需要以及非洲自身的资源和市场优势使得中国食用菌产业技术对非拓展市场成为可能。本文提出了加大选育适合当地的当家品种、控制生产规模扩张速度、加强技术人才的培养、充分运用国家相关优惠政策等建议，以推动我国食用菌产业技术对非合作与发展。
