Abstract

Cellulosic fibrous material such as wood chippings, cereal straws, bagasse &c. is preserved by impregnation with water containing (a) lactobacteriacae culturer upon the material itself at a temperature of 105-115 DEG F. so that unwanted bacteria are overwhelmed, (b) an independently prepared culture of other lactobacteracae which are selectivity active within the temperature range extending from the lower limit to be experienced during treatment up to the lower limit at which the first culture is active and (c) a nutrient if necessary. The first culture may be selctively active between 38 and 62 DEG C., the second culture, which may be prepared from milk, being selectively active between 28 and 40 DEG C. The material to be treated is impregnated with water containing the two cultures and molasses until the liquid/solid ratio is as high as possible (for bagasse it should be 3 : 1 to 4 : 1), and is then stacked and drained. With bagasse &c., the stack is compacted to reduce the quantity of air present and keep the temperature below 110 DEG F. Subsequent compaction and application of water may be used to keep the temperature down. With wood chippings, the stack is covered with a 6 inch layer of sawdust and kept damp to maintain the temperature below 120 DEG F.
