An industry spokesman said:"If biomass takes off, farmers could plant thousands of acres of land with energy crops such as willows and miscanthus, or elephant grass, a bamboo-type grass which would be harvested to fuel small power stations."

一位业界发言人说："如果生物质能被利用起来，那么农民就可以在数千英亩的土地上种植能源作物，如柳树、芒属植物或象草——一种类似竹子的草，可以用作小型发电厂的燃料。"

To verify whether it was safe or not in food processing, an acute toxicology experiment was carried out. The results of Horn's Method showed that LD50 of the endoenzyme extraction was higher than 21500mg/kg and thus was classified as no toxicity, while the microbe cells hadn't begotten the acute toxic effects with the biomass less than 1.72×109cfu/ml.

为了进一步研究其安全性，选用霍恩氏法测定半数致死量LD50，结果证明胞内酶提取液的经口LD50大于21500mg/kg，属于无毒级别，有必要进入后续阶段的毒理学试验；活菌制剂在1.72×109个/ml剂量以下不会引起急性毒性反应。

There exists a certain correlation between biomass of endophyte JJ18 and mortality.

生物量与杀螺率存在一定的相关性。

The genetic effects of the embryo and endosperm genes on rice seedling biomass at early stages were investigated in this paper.

本文利用胚和胚乳遗传模型研究了水稻早期胚后生长生物量性状的遗传控制。

The effects of different fed-batch methods on the biomass and ergosterol content in Saccharomyces cerevisiae were studied.

研究了不同流加操作条件对实验用酵母菌的生物量和麦角固醇含量的影响，以提高麦角固醇的发酵水平。

The structure of ergosterol crystal was characterized by UV, IR and SEM. A new approach of biomass source application was presented.

同时对玉米秸秆发酵产麦角甾醇晶体进行结构表征，为生物质资源的应用开辟新的途径。

The results show that not only the growth of C. wenyujin in lime soil is possible, but also the biomass, yield of medicinal part, the content of oil from the tuber and its medicinal components are higher than those from red soil. The C. wenyujin from lime soil quickly assumes etiolation during initial growth period. Surprisingly, the lusty leafs of C. wenyujin planted in red soil turn to pale and brown flecks occur in the leafs with the fertilization of N, P, K. It is concluded that C. wenyujin can be planted in lime soil; C.

结果表明：温郁金不但可以在石灰土上生长，而且其药用部位的产量、莪术油的含量及莪术油中主要药用组分β-榄香稀等的含量都较大；石灰土上生长的温郁金在生长前期较快地表现出老叶明显发黄的缺肥症状，而红壤植株在追加N、P、K 3种大量元素后功能叶子呈现黄白色，且夹带有褐色斑点的缺肥症状；石灰土中Fe元素有效态含量比红壤低一个数量级，但在石灰土上种植的温郁金植株其Fe元素含量并不比红壤上的低。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
