Seagrass Ecosystem

Seagrass ecosystem is one of tropical marine ecosystem and have important function. The function of ecosystem like a feeding and nursery ground for marine biota. Antrophogenic pressure is one of threat for seagrass ecosystem sustainability. This research study about effect antropogenic pressure for seagrass Thallasia hemprichii physiology response in some different location at Great Barrier Pari Island. The physiology response study cover growth, heavy metal bioaccumulation and histology analysis. The result shows that growth of leaf and rhizome Thalassia hemprichii have positif correlation with nutrient consentration in environment. The highest growth of leaf Thalassia hemprichii at 2nd station (4.16 mm.day-1) and the highest growth of rhizome Thalassia hemprichii at 4th station (1.3 mm.day-1). Seagrass can accumulation heavy metal from environment. The highest heavy metal accumulation is Pb. Not correlation between heavy metal consentration in seagrass with heavy metal concentration from environment. Analysis histology result that not damage seagrass tissue in all research station. Keyword : Bioacumulation,Growth,Physiology,Seagrass, Thalassia hemprichiiSeagrass ecosystems is one of the tropical marine ecosystems that have important functions, among others as a feeding and nursery ground for marine life. Anthropogenic stress is one of the threats that may inhibit the survival of seagrass ecosystems. This study examines the effects of anthropogenic pressures on physiological responses of seagrass Thalassia hemprichii at several different locations in Pari Islands. Physiological responses studied were leaves and rhizome growth, bioaccumulation of heavy metals and histological tissue analysis on seagrass. The results showed that the growth response of seagrass has a positive correlation with the nutrients in the environment. Seagrass leaf growth is highest at Station 2 (4.16 mm.day-1) and rhizome growth is highest at Station 4 (1.3 mm.day-1). Seagrass accumulate heavy metals from the environment and accumulation of heavy metals is highest on Pb. There is no correlation between the concentration of heavy metals in the seagrass and environment. The results of histological analysis showed that there was no damage to the tissue of seagrass leaf and rhizome. Keywords : Bio-acumulation, Growth, Physiology, Seagrass, Thalassia hemprichii

Close Proximity

The current study reveals the results of a phytoremediation process applied to a multi metal contaminated soil, located in close proximity to an energy power plant. Phytoremediation process was studied using the rapeseed cultivation, both in the presence and absence of hemp shives, considered as potential natural soil amendments. The physiological responses of the rapeseed plants, such as variations in length and accumulation of biomass, as well as the content of assimilating pigments were investigated. The concentrations of Cu (II) and Pb (II) ions have also been determined in soil and plants aiming at locating the metal ions in different organs of the plants. By using hemp shives as amendments, bioaccumulation of copper and lead ions in plant increases. The plants cultivated in the presence of high amounts of heavy metal ions have been characterized by an inhibition of growth and development that consisted in decrease of root and stem lengths, as well in the amount of biomass accumulated in different vegetative organs.

Transcription Activity

Depending on the physiological process investigated heavy metal phytotoxicity can be either inhibitory or stimulatory. Photosynthesis and its partial light and dark reactions are inhibited; the activity of various enzymes, located in several cell compartiments, is increased. These enzymes are mostly induced since metals affect the transcription activity. They appear to be related to the plant defence against oxidative stress caused by metal phytotoxicity. Careful examination of the time course of this induction reveals differences in response between the metals applied

High Output

It is worth mentioning that the high output of different physiological responses under the expression of vgb, may have a considerable effect on the enzyme productivity, dairy industry, heavy metal uptake, biodegradation of different organic pollutants and other applications. The expression of bacterial haemoglobin is useful in lessening the load of perceived toxic conditions such as high oxygen levels. This in turn probably has the same impact on some peripheral toxic materials. This, hemoglobin biotechnology can be extended to enhance production of pollutants degrading enzymes or production of some valuable manufacturing materials on the case-by-case bases. It is likely that the mechanism of bacterial hemoglobin (VHb) effects is intermediated via an oxygen trapping action. This may drive the enrichment of ATP production, which is mostly required for higher productivity of needed substances for that activity.
