We used Bacteriological studies to determine the quality of water, through quick methods, simple and sensitive detection of water contaminants, and in particularly bacteria that indicated the health status of water quality. We presented in this study
the effect of sewage on distribution nutrients and the Streptococci bacteria. Seven samples were taken during the period 2013 to 2014, at a rate of two cruises per season. Some of these samples were taken in near sewage stations, others, to make a comparison, were taken in distant ones. The study showed an increase in nutrients. These bacteria were linked to a positive relationship with nutrients because the presence of nutrients stimulated bacterial growth.
general study of counted Bacteria and Chlorophyll a Give us an initial picture to the environment safety and vitality of marine environmental, which constitutes one of the basic components. In this paper, we show the most important results related to
horizontal and vertical changes of temperature and counted Bacteria, the concentrations of dyes Chlorophyll a,phaeophytine and relationships between them to depth of 300 m. The study showed a high degree in deep-water temperature reached to about two degrees in recent decades. as well as significant decrease in counted Bacteria (800 - 12750CFU / 100 ml) and dyes Chlorophyll a (under detection threshold - 0.24 mg / l) and phaeophytine (under the detection threshold - 0.064 mg / l), which refers to the weakness in the wild tributaries and low nutrients that reaches to the beaches and marine wealth , which reflect the negative impacts on marine environment.
In this study, we review the possibility of production both ethanol and methanol from
OMW(OMW: Olive Mill Wastewater), fermented using pathogenic bacteria and isolated
marine bacteria. The results showed that when using Salmonella sp. bacteria, the
highest
values of methanol (5658.308 μg /l) appear at 7.5% concentration of the OMW, and the
higher concentration of ethanol (49.132 μg/l) at a concentration of 17.5% fermentation of
OMW. While Pseudomonas sp. produced the highest concentration of methanol (603.76μ
g/l) and ethanol (688.71μg /l) at 17.5% for OMW.
The results of this research showedthe ability of the bacteria isolated from sea water
in producing the above mentioned alcohols; for example the X3 bacteria displayed a direct
correlation between high concentrations of OMW (15 , 35 , 50)% and the high
concentrations of produced methanol (UL, 130.406μg/l, 1353.244μg/l ), apposite to
ethanol which was under the detection limits (under limited: UL).
