ISOLATION AND CHARACTERISATION OF CELLULOSE NANOCRYSTAL OBTAINED FROM SUGARCANE PEEL

Isolation and Characterisation of Endophytic Nitrogen Fixing Bacteria in Sugarcane.

Endophytic nitrogen fixing bacteria were isolated from the leaves, stems and roots of industrial variety (cv. U-Thong 3; UT3), wild and chewing sugarcane plants grown for 6 weeks in nitrogen (N)-free sand. Eighty nine isolates of endophytic bacteria were obtained on N-free agar. An acetylene reduction assay (ARA) detected nitrogenase activity in all 89 isolates. Three isolates from the chewing ...

Synthesis, Characterisation and Flocculation Properties of Carboxymethyl Cellulose-g Acrylamide

Graft copolymers of acrylamide on carboxymethyl cellulose (d.s 0.4-0.5) were prepared by the use of ceric ion, ceric ion/reductant molecule initiator systems in aqueous medium. The graft copolymers were characterized by IR spectroscopy. The extent of graft copolymerisation was measured in terms of grafted chains as a function of both ceric ion and ceric ion/reductant molecule concentrations. It...

Isolation and Characterisation of Some Endophytic Bacteria from Papua New Guinea Sugarcane

Endophytic bacteria were isolated from the stalks of sugarcane, Saccharum officinarum, growing in Papua New Guinea. Endophytic bacterial communities from extracted juice averaged 6x 10 cfu/ml, which is 25 times greater than the number of endophytic bacteria found in commercial varieties in South Africa. Sixty isolates, representing the different colony morphology types, were used for in vitro i...

Isolation and Characterisation of Anti-diabetic Pharmacological Activities of Phytoestrogens

Isolation and Characterisation of Actinobacteria from Algerian Sahara Soils with Antimicrobial Activities

Extreme ecosystems can be a source of untapped micro-organisms able to produce novel bioactive compounds of industrial interest. Consequently, in this work, 32 Actinomycetes were isolated from 6 soil samples collected from Algerian Sahara in searching for untapped producers of novel antimicrobial compounds. All the isolates were further subjected to antimicrobial screening against pathogenic ba...
