Nodules developed within 50 days.Photomicrograph of nodule cells showed that the capsulated bacteria were intrarellular.Rhizobia reisolated from the root nodules retained not only the ability of nodulation but also the characteristic of resistance to 100 μg neomycin mL-1.A low nitrogenaSe activity of the nodules was determined by the method of acetylene reduction.展开更多

The fibre strength properties were tested using SIRIM Standard methods and colour changed using gray scale. The bioaugmentation of pectin decomposing bacteria together with MgO additions were found to enhance retting process and reduced retting periods 52% and yielded better strength on the fibres. The lower portion pseudo-stem sheaths gave the higher strength than upper portion. Colour changed showed that the bioaugmentation of pectin bacteria enhanced the degradation colouring compound in banana fibres.展开更多
