Morphology Terrabacter tumescens
Morphology The norcardioforms form a fugacious mycelium that breaks up into rod shaped or coccoid elements long rods show primary branching cells from older cultures aer coccoid (0.5-0.8 um in diameter) After transfer to fresh comlex media, long irregular rods (0.6-1.2 x 2.0- 60 um) are formed
Motility usually non motile although motile strains do occur
Specialized structures rod-coccus growth cycle occurs druing growth on complex media
Solid surface aerial mycelium is not produced


Growth Parameters Terrabacter tumescens
Temperature growth range 10-35 oC, optimum 250 30 oC, does not survie heating to 63 oC for 30 min
Requirements Thiamine is required for growth
Products acid not produced from sugasrs in peptone based media, cellulose not hydrolysed, nitrate reduced to nitrite

Cells contain diphosphatidylglycerol, phosphatidylethanolamine and phosphatidiylinositol as major phospholipids. some unidentified amino contining phosphoglycolipids are present. Tetrahydrogenated menequinone with eight isoprene units is the predominant isoprenolog

Enzymes oxidase negative
Unique features growth in the presence of 5% NaCl
Habitat soil
