Physiological, Biochemical and Morphological Characteristics of Mesquite Wood-digesting Bacteria

The effect of rhizospheric bacteria on the physiological and biochemical characteristics of safflower (Carthamus tinctorius)

Rhizospheric bacteria are among the beneficial soil microorganisms that improve plant growth. These bacteria increase plant growth through various mechanisms such as the production of various phytohormones and the ability to solubilize phosphate. The aim of this study was to investigate the effects of rhizosphere bacteria on the growth of Carthamus tinctorius to improve its physiological and bi...

Isolation of lactic acid bacteria during fermentation of cereals using morphological, physiological and biochemical techniques

The lactic acid bacteria (LAB) involved during the spontaneous fermentation of cereals (maize,millet, sorghum) for the production of indigenous foods (‘akamu’, ‘kunu-zaki’) were quantified and identified. The lactic acid bacteria counts varied during the fermentation of the cereals while the titratable acidity (TTA) increased with reduction in pH. Identification of isolates using API 50CHL syst...

Studies of Agar-digesting Bacteria.

Facultative wood-digesting bacteria from the hind-gut of the termite Reticulitermes hesperus.

Among the facultative bacteria capable of growth on mesquite wood which were isolated from the asceptically dissected hind-gut of the termite Reticulitermes hesperus were two strains of Bacillus cereus, one strain each of Arthrobacter, Alcaligenes and Serratia, and a very small Gram-negative fermentative rod. The B. cereus strains, the Serratia marcescens strain and the Arthrobacter sp. grew we...

The Microbacteria: I. Morphological and Physiological Characteristics.

The genus Microbacterium was proposed by Orla-Jensen in 1919. Four species were described, viz., Microbacterium lacticum, Microbacterium flavum, Microbacterium liquefaciens, and Microbacterium mesentericum. The organisms of this genus presented a physiological gradient with the saccharolytic acid former (M. lacticum) at one extreme and the proteolytic gelatin liquefier (M. liquefaciens) at the ...
