The present study aims to use banana pseudostem waste for the production of potassic biofertilizer using cellulolytic bacteria. Ten cellulolytic bacteria were isolated from soil samples collected from the College campus. After preliminary tests and biochemical tests, the cellulolytic bacteria were identified. The bacterial isolate which showed maximum cellulolytic activity (D8) was found to be Bacillus aerius by 16s rRNA sequencing. Its 16s rRNA sequence was submitted to Genbank and the accession number is KX530930.Appreciable amount of cellulolytic activity were shown by five different bacterial genera which were identified as Bacillus circulans (C3), Pseudomonas stutzeri (C4), Serratia rubidaea (C6),Bacillus subtilis (D1) and Bacillus pumilus (D2). These isolates were used alone and in consortium to degrade the banana pseudostem waste by solid state fermentation to obtain the fermented liquid. Analysis of the potassium content of the liquid by ICP-MS indicated that the potassium content is directly proportional to the cellulolytic activity of the bacteria. Tests done to check the effect of fermented liquid on plant growth revealed good increase in root length, shoot length, fresh weight, dry weight and chlorophyll content of fenugreek plants.
