衣藻与黄丝藻在硫酸铜污水中的富集效应

在春、夏两季选择３个采样点及１个对照点，样品经过ＩＣＰ等检测，结果发现，衣藻（Ｃｈｌａｍｙｄｏｍｏｎａｓ）在该污水中具高富集铜等效应，是污水处理的理想藻种。     

银耳双核菌丝隔膜孔帽的超微结构

在银耳（Ｔｒｅｍｅｌｌａｆｕｃｉｆｏｒｍｉｓ）双核菌丝隔膜孔器超微结构的研究中，发现银耳孔帽分子横切时为两平行条形，而不是环形。只有折叠片层体的横切面才呈两平行条形，纵切面呈Ｕ形，如果斜—纵切折叠片层体的基部则为开口环形（其实是Ｕ形）。因此，作者认为圆顶形孔帽不是由许多杯状体组成，而是由众多折叠片层体组成。为了说明银耳型多单位的折叠片层体孔帽不同于单一单位的括孤体孔帽，特把银耳型的隔膜孔器命名为桶孔／叠层体隔膜（ｄｏｌｉｐｏｒｅ／ｌａｍｉｎａｔｅｓｏｍｅｓｓｅｐｔｕｍ），以区别于其他担子菌的桶孔／括弧体隔膜（ｄｏｌｉｐｏｒｅ／ｐａｒｅｎ－ｔｈｅｓｏｍｅｓｅｐｔｕｍ）。     

鸡Zong菌菌丝体液体培养的研究

适合鸡Ｚｏｎｇ菌菌丝液体培养的培养基成分是：淀粉１０ｇ，蔗糖２ｇ，蛋白胨２ｇ，ＫＨ２ＰＯ１０．３ｇ，ＭｇＳＯ４．７Ｈ２Ｏ０．１５ｇ；最佳Ｃ／Ｎ为３０－４０：１；最适培养温度２６Ｃ；ｐＨ６．４；振荡频率１４０－１５０ｒ／ｍｉｎ。继代培养周期８天，液体培养的鸡Ｚｏｎｇ菌菌线体氧基酸总可达２７３ｍｇ／ｇ干重，其中４２．４１％为人体必需的氨基酸（未含色氨酸）。     

Discussion on Plain Stitch Embroidery in Early China Based on New Unearthed Materials

Plain stitch embroidery of Han Dynasty and before is rarely unearthed. Among the large amount of embroidery excavated from Haiqu ( 海曲 )Han tombs in Rizhao( 日照), Shandoug, an embroidery fragment with plain stitch was found. This is the first plain stitch embroidery with a typical cloudy pattern in Han Dynasty unearthed up to now. And its needlework was very skillful. Combining the two pieces of plain stitch embroidery on wool fabrics found in Wubao( 五堡) tomb at Hami (哈密 ) Xinjiang and Mawangdui ( 马王堆 )Han tombs, we recognized that the application of plain stitch was earlier than scholars considered before. As basic plain stitchwork was poorer in art expression than chain stitchwork, it was less adopted in extravagant silk embroidery. But for ordinary status, plain stitch was more popular to be used in embroidery.     

鸡(土从)菌(Termitomyces albuminosus)小白球培养研究

从白蚁巢(菌台、菌圃)(comb)上分离培养出产生鸡(土从)菌(Termitomyces albumi-nosus)子实体原基的小白球(spherules),菌台上除优势种鸡(土从)菌外,还发现绿色木霉(Trichoderma viride)、青霉(Penicillium sp.)、拟青霉(Paecilomyces sp.)、炭角菌(Xylaria sp)和酵母类(yeast)等真菌共同组成一个真菌“群落”;为模拟鸡(土从)菌的营养条件,还检测了菌台的化学成分。     

鸡堫菌菌丝体液体培养的研究

适合鸡菌菌丝体液体培养的培养基成分是：淀粉１０ｇ，蔗糖２ｇ，蛋白胨２ｇ，ＫＨ＿２ＰＯ＿４０．３ｇ，ＭｇＳＯ＿４·７Ｈ＿２Ｏ０．１５ｇ；最佳Ｃ／Ｎ为３０～４０：１；最适培养温度２６℃；ｐＨ６．４；振荡频率１４０～１４５ｒ／ｍｉｎ，继代培养周期８天．液体培养的鸡菌菌丝体氨基酸总量可达２７３ｍｇ／ｇ干重，其中４２．４１％为人体必需的氨基酸（未含色氨酸）．
