In degradative processes where hydrogen or acetate are waste products, these methanogens can thus increase the thermodynamic favorability by reducing hydrogen and acetate concentrations and in effect drive the degradative process forward [66].
The present study showed the chondro-protective effect of naringenin on the expression and secretion of several degradative enzymes, particularly MMP-3.
When compared with the degradative decolourisation of RBBR dye by isolate MS8, the increase in enzyme activities coincides with the rapid decrease of RBBR dye from day 0 to day 9 (Figure 2).
The acidic condition applied on the active drug substances for 2 days induced the hydrolysis of florfenicol causing assay loss of about 10.5% and degradative material (Fr3) of about 11%, while no degradation was observed for flunixin.
These isolates were found among those having minimum pectin degradative properties as indicated by the zone sizes.
Indeed, ubiquitin was found to be covalently associated with the insoluble material of NFT and SP [50-52], thus suggesting that something in the degradative systems did not work properly.
The heat aging conditions were not severe, but above 70[degrees]C natural rubber tends to start undergoing degradative processes that are not typical at room temperature, so it was considered more appropriate to go no higher; and 70 hours in an air circulating oven is an appreciable time for aging to occur.
This repair leads to an increase in degradative enzyme activity, sites of focal wound healing and tissue remodelling.
This often results in adaptation of the autochthonous organisms to the pollutants due to selective pressure and acquisition of degradative abilities [30].
On the other hand, because plasma homocysteine was thought to be a risk factor for cardiovascular disease, vitamin [B.sub.6] is widely recognized for its importance in the inactivation of homocysteine by serving as coenzyme in the form of PLP for two degradative enzymes (cystathionine [beta]-synthase and cystathionine [gamma]-lyase) in the transsulfuration pathway for homocysteine removal (Selhub, 1999; Miles and Kraus, 2004).
Claim 2: A bacterium from the genus Pseudomonas containing therein at least two stable energy-generating plasmids, each of said plasmids providing a separate hydrocarbon degradative pathway.
