The interrelationship between abscisic acid (ABA) production and β-carotene accumulation
was investigated in salt-stressed cells of the halotolerant green alga Dunaliella salina var …

Dendritic cells (DC) are the most potent antigen-presenting cells and are fundamental for
the establishment of transplant tolerance. The Dendritic Cell-Specific Intracellular adhesion …

Cynodon dactylon (Bermuda grass) has been observed to grow sporadically on the surface
of coal dumps in the Witbank coal mining area of South Africa. Root zone investigation …

Polyphenol oxidase (PPO), obtained from Agaricus bisporus, can be used in hydroxylating
a range of phenolic substrates to yield catechols which are then oxidised by the enzyme to …

A kinetic study of the activity of mushroom polyphenol oxidase in an organic system was
carried out to obtain detailed enzyme kinetic data in relation to optimization of reaction …

The sporadic growth of Cynodon dactylon was observed to occur directly on the surface of
hard coal in dumps of the Witbank coal mining area of South Africa with the surface coal being …

Fundamental processes involved in the microbial degradation of coal and its derivatives
have been well documented. A mutualistic interaction between plant roots and certain …

The community structure of complex microbial consortia which develop in lignocellulose
packed passive treatment systems for acid mine drainage remediation were investigated. An …

Acid mine drainage waters are characterised by a low pH, high concentrations of heavy
metals, high levels of sulphate salts and low concentrations of organic material. The biological …

The system offering low-tech low-cost treatment of municipal sewage is described. It is
based on a ponding process followed by a trickling filter (TF). Micro-algae produced in …
