双孢蘑菇培养料隧道发酵技术是将培养料按照配方要求精准配料，通过预湿、混料环节进入一次发酵隧道，在75～80 ℃ 条件下完成微生物发酵及焦糖化反应，然后转入二次发酵隧道，在58～60 ℃ 条件下进行巴氏杀菌杀虫，45～50 ℃ 条件下进行控温发酵，生产出的培养料理化性状稳定，利于双孢蘑菇菌丝生长。实践证明，采用工厂化生产的二次发酵料栽培双孢蘑菇，出菇产量可较传统发酵料栽培提高60%～120%。 相似文献

蘑菇培养料的常规堆料和二次发酵(又称后发酵)过程中都要进行翻料堆,不但花工多,而且劳动强度大。常规堆料,因堆料时间长,培养料堆制过熟,养分流失多,加之堆料全过程是在室外,培养料堆制的质量受到不利天气的影响,蘑菇产量低.二次发酵是对常规堆料法的改进,可缩短堆料时间,将料移进室内床架上进 相似文献

不同发酵方式制备的小麦草蘑菇培养料的质量及蘑菇的产员有较大的差异。试验结果表明,在其它条件相同的情况下,室内二次发酵的培养料比室外一次发酵的增产40.8％;室外堆制发酵翻堆两次后,改小堆进行空心发酵的培养料比室外一次发酵的增产33.8%,其增产幅度同室内二次发酵的较为接近,且耗资少,省工简便。 相似文献

二次发酵，亦称为后发酵。因为一般情况下。二次发酵是在室内或棚内进行的，所以通常也称为室内发酵或棚内发酵。二次发酵能够明显提高单位面积产量，增产幅度为20％-40％，就是我们常说的30％左右。 相似文献

AIM: To detect the expression of cytoplasmic inhibitor of apoptosis protein 2 (c-IAP2) and growth arrest-specific gene 1 (GAS1) in Hodgkin's lymphoma (HL) and anaplastic large cell lymphoma (ALCL) and to investigate the role of two genes in the pathogenesis of HL and ALCL.METHODS: HE staining, the antibodies CD30, CD15, CD45RO and CD20 were used to screen the cases of HL and ALCL from 288 cases of lymphoma. The clarified HL and ALCL were subjected for immunohistochemical staining by SP and ABC methods to analyze the expression of c-IAP2 and GAS1. RESULTS: ①The positive rate of c-IAP2 in HL was 25/26(96.1%) while that in ALCL was 6/19(31.6%), there presented statistic significance between HL and ALCL groups(P<0.05), meanwhile the positive rate of GAS1 showed statistic significance between HL and ALCL groups(P<0.05). ②Two cases were showed to be a mixed type combined with large tumor cells of HL and relatively smaller tumor cells of ALCL.CONCLUSION: ①The different expression of c-IAP2 and GAS1 in HL and ALCL implied a different mechanism of oncogenesis and the different defects in the pathway of signal transduction of apoptosis in HL and ALCL;②Few cases showed an overlap and a likely transitional state between HL and ALCL; ③The different expressing manner of GAS1 and c-IAP2 in HL and ALCL implied the potential marks for the differential dignosis of two kinds of lymphoma. 相似文献

Burger and Page (this volume) evaluated our models of habitat preferences and breeding success of a threatened seabird, the
marbled murrelet (Brachyramphus marmoratus), based on the largest available set of confirmed nest-sites found in coastal old-growth forest of the Pacific North-West.
We believe our study documented novel and unexpected patterns of landscape-level distribution of marbled murrelets in both
heavily logged and relatively intact old-growth landscapes and provided insights into how these patterns influence their reproduction,
and, eventually, management. Considering the importance of the issue and to ensure appropriate and responsible use of the
information we welcome discussion, detailed scrutiny and evaluation of our original results. Burger and Page claim to have
identified flaws with model interpretation, data quality, statistical approaches, presentation and interpretation of our results
that would invalidate our conclusions. We respond that most of their critique is irrelevant and/or misdirected with respect
to our study and the interpretation of GIS data models, and that valid aspects of their claims do not critically affect our
conclusions. 相似文献

AIM:To Study on the expressive levels of PTTG and FHIT and detect their clinicopathological significances in gastric cancer and pericancerous tissues.METHODS:Immunohistochemical method was used on routinely paraffin-embedded sections of 49 cases with gastric cancer and 20 subjects with pericancerous tissues. RESULTS:The positive rate and score of PTTG in gastric cancer were significantly higher than those in pericancerous tissues (P<0.05,P<0.01),but those of FHIT were opposite (P<0.05,P<0.01),the positive cases of PTTG and negative subjects of FHIT showed severely-atypical hyperplasis. The positive rate and score of PTTG were significantly lower in the cases of infiltrating depth T1-T2 and without-metastasis of distant organs than those in the subjects of infiltrating depth T3-T4 and with-metastasis of distant organs(P<0.05,P<0.01). The positive rate and score of FHIT were significantly higher in the cases of infiltrating depth T1-T2,without-metastasis of lymphnodes,with-metastasis of the first site lymphnodes,and without metatstasis of distant organs than those in the subjects of infiltrating depth T3-T4,with-metastasis of lymphnodes,with-metastasis of the third site lymphnodes,and with-metastasis of distant organs(P<0.05,P<0.01). The significantly negative correlation was found between the score of PTTG and FHIT in gastric cancer tissues(r=-0.36,P<0.01). CONCLUSION:The expression of PTTG and FHIT might be important biological markers for reflecting the carcinogenesis,progression,invasive potential,metastastic status and prognosis of gastric cancer. The assays of PTTG and FHIT in benign lesions might have clinical values for the prevention and early-stage finding of gastric cancer. 相似文献

嫁接辣椒对青枯病的抗性及其与渗透调节物质的关系 总被引：3，自引：0，他引：3
青枯病是当前设施辣椒主要的土传病害之一。为了选择抗性砧木和探讨嫁接辣椒的抗病机理,通过人工接种青枯病原菌,分析了不同辣椒品种砧木的发病率和病情指数变化,结果表明：‘富根卫士’（简称‘卫士’）发病晚,发病率低,病情指数最小,抗病性最强。以‘卫士’辣椒为砧木,以‘新丰2号’为接穗进行嫁接,以接穗自根嫁接为对照,研究其发病率、病情指数和渗透调节物质的变化。结果表明：嫁接植株的发病率和病情指数显著低于对照,接种20 d时,嫁接植株发病率和病情指数分别比对照低33%和43%。接种前嫁接的植株根系和叶片的含水量、水势、渗透势均低于对照,束缚水/自由水比值、可溶性糖及脯氨酸含量均高于对照。接种后,辣椒根系和叶片的含水量、水势、渗透势均逐渐降低,束缚水/自由水比值逐渐升高,可溶性糖和脯氨酸含量先升高后降低;与对照相比,嫁接植株根系和叶片的含水量、水势、渗透势的降低幅度及束缚水/自由水比值升高幅度明显较小,可溶性糖和脯氨酸含量显著增加。研究结果表明嫁接可显著提高辣椒青枯病的抗性,其抗病机理与渗透调节能力增强有关。 相似文献
