RESUMO
In order to clarify the cellulose-utilizing mechanism of the Cerambycidae, the microorganism in the Apriona germari(Hope) larvae's gut was cultured and identified. A strain of facultative anaerobic cellulose-utilizing bacteria was isolated from the midgut fluid of A. germari larvae with the cellulose-congo red agar medium. The colonies of the bacteria were white and round with regular margin. Clear zones of cellulolysis surrounding the colonies might reach 10m～20mm. The size of the bacteria was 0.5μm～0. 8μm× l～3μm approximately. The cell was gram-positive rod with polar flagella. It hadn't spores. With the results of biochemical tests, the bacteria were tentatively identified as Cellulomonas.

The colonies of the bacteria were white and round with regular margin. Clear zones of cellulolysis surrounding the colonies might reach 10mm～20mm. The size of the bacteria was 0.5?m～0.8?m?1～3?m approximately. The cell was gram positive rod with polar flagella. It hadn't spores. With the results of biochemical tests, the bacteria were tentatively identified as Cellulomonas.
