大曲前期培养指在低中温(品温55℃以下)的培养阶段。试验曲与常规曲比较结果表明,前期培养时间多5d,升温缓慢,两种曲培养温度差别较大;糖化力较高,酸度低;曲香较浓;曲中微生物总数较多;试验产酒中己酸乙酯比常规曲高620mg/L,而乙酸乙酯... 大曲前期培养指在低中温(品温55℃以下)的培养阶段。试验曲与常规曲比较结果表明,前期培养时间多5d,升温缓慢,两种曲培养温度差别较大;糖化力较高,酸度低;曲香较浓;曲中微生物总数较多;试验产酒中己酸乙酯比常规曲高620mg/L,而乙酸乙酯低791mg/L;试验曲能提高湘泉酒中己酸乙酯含量,大大降低乙酸乙酯和乳酸乙酯含量。 展开更多

在清香型中温大曲的前期培养中,常出现“水毛”和“干皮”病害,造成大曲质量下降。“水毛”主要发生在上霉阶段和晾霉阶段,因曲坯水分过大造成,可通过调整工艺,提高制曲温度,及时排潮加以克服。夏秋季,延长晾曲时间为10~12h;冬春季,人... 在清香型中温大曲的前期培养中,常出现“水毛”和“干皮”病害,造成大曲质量下降。“水毛”主要发生在上霉阶段和晾霉阶段,因曲坯水分过大造成,可通过调整工艺,提高制曲温度,及时排潮加以克服。夏秋季,延长晾曲时间为10~12h;冬春季,人工增加室温,控制水分。“干皮”主要形成于晾霉期间,影响感官质量,降低曲利用率,影响曲坯的后期培养。造成“干皮”的原因一是上霉不好;二是晾霉期间排潮太快;三是晾霉与潮火之间升温过猛。克服办法:上霉期间控制好培养温度和湿度,保证曲子上霉良好;晾霉期间,先揭席,缓开窗,减缓排潮速度;曲子入房后前8d内控制品温在38℃以下,可减少“干皮”现象。(小雨) 展开更多

Expression of the adhesion molecules, ICAM-1, VCAM-1, NCAM, CD44, CD49d (VLA-4, a chain), and CDlla (LFA-1, a chain) on mouse oocytes, and pre- and peri-implantation stage embryos was examined by quantitative indirect immunofluorescence microscopy. ICAM-1 was most strongly expressed at the oocyte stage, gradually declining almost to undetectable levels by the expanded blastocyst stage. NCAM, also expressed maximally on the oocyte, declined to undetectable levels beyond the morula stage. On the other hand, CD44 declined from highest expression at the oocyte stage to show a second maximum at the compacted 8-cell/morula. This molecule exhibited high expression around contact areas between trophecto-derm and zona pellucida during blastocyst hatching. CD49d was highly expressed in the oocyte, remained significantly expressed throughout and after blastocyst hatching was expressed on the polar trophecto-derm. Like CD44, CD49d declined to undetectable levels at the blastocyst outgrowth stage. Expression of both VCAM-1 and CDlla was undetectable throughout. The diametrical temporal expression pattern of ICAM-1 and NCAM compared to CD44 and CD49d suggest that dynamic changes in expression of adhesion molecules may be important for interaction of the embryo with the maternal cellular environment as well as for continuing development and survival of the early embryo. 展开更多

The objectives of this study were to assess the potential of two photosynthetic bacteria (PSB), Rhodopseudomonas palustris HZ0301 and Rhodobacter sphaeroides HZ0302, as probiotics in aquaculture. The viability of HZ0301 and HZ0302 in simulated gastric transit conditions (pH 2.0, pH 3.0 and pH 4.0 gastric juices) and in simulated small intestinal transit conditions (pH 8.0, with or without 0.3% bile salts) was tested. The effects of HZ0301 and HZ0302 on the viability and permeability of intestinal epithelial cell in primary culture of tilapias, Oreochrornis nilotica, were also detected. All the treatments were deter- mined with three replicates. The simulated gastric transit tolerance of HZ0301 and HZ0302 strains was pH-dependent and correspondingly showed lower viability at pH 2.0 after 180 min compared with pH 3.0 and pH 4.0. Both HZ0301 and HZ0302 were tolerant to simulated small intestine transit with or without bile salts in our research. Moreover, there was no significant difference (P〉0.05) among three treatments including the control and the groups treated with HZ0301 or HZ0302 both in intestinal epithelial cell viability and membrane permeability, showing no cell damage. In summary, this study demonstrated that HZ0301 and HZ0302 had high capacity of upper gastrointestinal transit tolerance and were relatively safe for intestinal epithelial cells of tilapias. 展开更多
