社区发展是中国国家公园体制建设的重要组成部分,纾解国家公园建设与社区发展的隐性冲突对于实现国家公园高质量发展至关重要。为回答隐性冲突呈现何种特征、由何引发、何以纾解的问题,本文以东北虎豹国家公园为典型案例,基于从国有森工企业及其所属林场、村屯获取的93份质性材料与452份调查数据,从冲突的客体、主体和表现形式三个方面深描隐性冲突的表现特征,并引入制度逻辑视角解构隐性冲突的形成逻辑。研究结果表明:物质利益减少、社会资源受限、权利配置不合理与身心健康受损引发的社区居民与其他行为主体的情绪对立,是隐性冲突最具代表性的表现特征;国家公园场域内的制度逻辑存在内在缺陷、行为主体响应策略不完善且调适策略有效性不足是隐性冲突产生的原因。本文从完善生态制度逻辑、健全购买服务策略、优化保险理赔策略和探索构建调适策略四个方面提出纾解方案。本文的研究发现深化了对隐性冲突及其产生机理的理解,并对国家公园治理的策略选择具有实践启示。

为提高发酵蔬菜的安全性和保藏性,从来自云南传统发酵蔬菜的8株明串珠菌中筛选出1株对食源性致病菌和引起泡菜过酸化的细菌抑制效果好的肠膜明串珠菌AP7。通过排除酸和H2O2影响及蛋白酶敏感性确定AP7的主要抑菌物质,分析其酸稳定性和热稳定性,根据AP7的全基因组序列挖掘潜在的细菌素基因簇。结果表明:排除酸及H2O2的影响后,菌株的发酵上清液仍具有明显抑菌活性,经蛋白酶处理后,抑菌效果明显下降,推测AP7发酵上清液浓缩液中的抑菌物质为细菌素;该细菌素对pH变化敏感,热稳定性高,分子质量在6.51~14.4 kDa;全基因组测序表明,菌株AP7全基因组包含1条染色体(1948310 bp)和2个质粒(37366和20698 bp),GC含量37.7%;存在1个以Enterocin_X_chain_beta细菌素为核心的基因簇,其编码产物预测为带正电的亲水性稳定蛋白,二级结构以α-螺旋为主,三级结构主要由两端松散肽链和中间α-螺旋构成。综上,产细菌素的肠膜明串珠菌AP7具有优良抑菌性能,有潜力应用于酸性食品的发酵和防腐。

Whole wheat flour is a food raw material rich in macronutrients， but its application in baking industry is limited due to the existence of a large amount of insoluble dietary fiber in bran. In order to make full use of this resource， we first screened twelve cellulase-producing strains， and then extracted soluble dietary fiber (SDF) from whole wheat flour after fermentation with 3 strains of Aspergillus sp. and 2 strains of Bacillus sp.， respectively. The effects of different strains on nutritional characteristics， SDF yield， structure improvement， and antioxidant activity of whole wheat flour were compared. The results showed that fermentation of whole wheat significantly increased the yield of SDF， the content of nutritive active substances， and improved the physicochemical structure and antioxidant activity of SDF in vitro. Scanning electron microscopy (SEM)， X-ray diffraction and liquidity characteristics show that the fermentation to make whole wheat SDF has more porous microstructure and crystallinity of lower molecular weight. Fourier transform infrared spectrum showed that there were differences in functional group types between C-SDF and F-SDF. These changes together improved the hydration performance and antioxidant activity of whole wheat SDF， including water holding capacity， oil holding capacity， cholesterol adsorption， DPPH， ABTS and hydroxyl radical scavenging， and lipase activity inhibition. Bacillus sp. SH and Aspergillus oryzae Y21 are ideal strains for fermentation of improved whole wheat， which has the potential of antioxidant properties while improving nutritional properties and food quality.

Compared to refined wheat flour， whole wheat flour contains higher nutrients， but its high content of dietary fiber can have a significant impact on the quality of the final product. Therefore， how to enable consumers to obtain health benefits from whole wheat flour and improve the processing performance of whole wheat products has become a concern. The purpose of this study is to apply two strains Bacillus sp. SH and Aspergillus oryzae Y21 with cellulase production capacity and study their adaptability in whole wheat dough. The results indicate that the addition of cellulase-producing strains enhanced the acid production ability of whole wheat dough， rapidly reduced its pH value and insoluble dietary fiber content， and significantly increased the water-soluble arabinoxylan and water-soluble dietary fiber content. During the fermentation process， the viscoelasticity of the dough decreased， free sulfhydryl content increased， wet gluten content decreased， and the degree of reduction was consistent with the degree of acidification. Moreover， the proteolytic activity of the dough was increased， and the hydrolysis of gliadin was the most extensive. Bacillus sp. SH showed a higher advantage and has been used in whole wheat bread making. Increasing the proportion of strain SH in whole wheat bread can improve the structural characteristics and texture of the bread. When SH (5 × 107CFU/g) is added to whole wheat bread， its hardness， elasticity， chewiness， and resilience can be similar to those of bread made from control group wheat flour， far exceeding that of whole wheat bread without adding SH. The addition of cellulase producing strains has obvious advantages in the development of whole-wheat dough， and also promote the development of whole wheat fermented foods as staple foods.

新生儿PICC常见并发症的临床护理干预效果

中国菌物学会2018年学术年会

Morchella is a popular edible fungus worldwide due to its rich nutrition and unique flavor. Many research efforts have been made on the domestication and cultivation of Morchella all over the world. In recent years, the cultivation of Morchella has been commercialized successfully in China. However, the weak biological basis has restricted the further development of the morel fungus cultivation industry. In this paper, we performed the de novo sequencing and assembly of the genomes of two monospores with a different mating type（M04M24and M04M26） isolated from the commercially cultivated strain M04. Gene annotation and comparative genome analysis were performed in terms of CAZYme enzyme lines, transcription factors, duplication sequences,structure of mating type sites and differences at the gene and functional levels between the two monospore strains of M. importuna. Results showed that the de novo assembled haploid M04M24 and M04M26 genomes were48.98 Mb and 51.07 Mb, respectively. A complete fine physical map of M. importuna was obtained from genome coverage and gene integrity evaluation. A total of 10,852 and 10,902 of common genes and 667 and 868 of endemic genes were identified from the two monospore strains, respectively. The GO and KAAS enrichment analyses showed that the endemic genes performed different functions. The two monospore strains had 99.22%collinearity with each other, accompanied with certain position and rearrangement events. Analysis of complete mating-type loci revealed that monospore M. importuna strains contained an independent mating-type structure and remained conservative in sequence and location. The phylogenetic and divergence time of M. importuna was analyzed at the whole-genome level for the first time. The bifurcation time of morel and tuber was estimated to be201.14 millions of years ago（Mya）, the two monospore strains with a different mating type represented the evolution of different nuclei, and the single copy homologous genes betw
