The aim of the research was to find out the effect of some acidic pre
servatives on the pseudomonas of the cultivars, which are considere
d the main cause of the spoilage of trout meat in different degrees of
cooling.
The susceptibility of some varieties grown locally of common bean
has been evaluated for both pseudomonas savastanoi pv
phaseolicola which causes halo blight and xanthomonas axonopodis
pv phaseoli which causes common bacterial blight. Five locally
cultivated varieties were planted in green house under natural
conditions.
Pyocyanin was extracted from cultures of Pseudomonas
aeruginosa, which was isolated from sea water by chloroform.
Results study the effect of pyocyanin against human pathogenic
bacteria, which were isolated from Al-Assad hospital laboratory in
La
ttakia, with disk diffusion method showed that pyocyanin has
antibacterial activity against Gram- positive bacteria.
Samples of Trout dived into aqueous extract of ginger in different
concentrations (5-15-25)% for one minute and then preserved at 4±1
cº for 13 days. It has studied the effect of aqueous extract of ginger
in bacterial load, including general bacterial census and the census
of pseudomonas. It was also identified the values of the pH and
some organoleptic qualities of meat such as color, smell, texture and
taste.
The research aims to study the possibility of lengthening Remember
chicken meat, chilled by his treatment extracts the oily plant
cardamom, cinnamon, Zingiber and also curb the role of the
pseudomonas bacteria in chicken meat spoilage through
conservation radiator with anti impact during the oily extracts.
This research was conducted to study the effect of four bacterial strains (PGPR):
Pseudomonas chlororaphis MA342, Serratia plymuthica HRO-C48, Bacillussubtillis
B2g and B. subtillis FZB27 to improve the growth of tomato plants in the greenhouse.
B
acterial strains were applied to the seeds in a concentration of (1010 cfu/ml), of each
bacterial strain.
The study was conducted to evaluate the efficiency of Pseudomonas chlororaphis MA342,
Serratia plymuthica HRO-C48K, Bacillus subtillis B2g, B. subtillis FZB27 to induce systemic
resistance in Tomato plants against Cucumber mosaic virus (CMV) under
greenhouse conditions.
Tomato seeds submerged in suspension of Pseudomonas chlororaphis MA342, Serratia
plymuthica HRO-C48, Bacillus subtillis B2g and B. subtillis FZB27 9×109cfu . plants emerged
from these seed were inoculated with CMV after 10 days of planting. The time of beginning
symptoms was recorded, Disease incidence, disease severity, area under disease progress curve
AUDPC, progress of infection disease degrees during the study period were calculated using
virtual symptoms . pyroxidas enzyme activity was determined, Some growth parameters such as
Plant height, foliage fresh weight, root fresh weight , foliage dry weight, root dry weight were
observed after 30 DAI. Results of this study showed that seed treatment with Pseudomonas
chlororaphis MA342, Serratia .plymuthica HRO-C48, Bacillus subtillis B2g, B. subtillis FZB27
significantly decreased the diseases incidence on treated and inculated plants which ranged
between 40% - 66.66% ,compared with un treated and inculated control 93.33% Without the
presence of significant differences between the bacterial treatments. significantly decreased the
diseases severity on treated plants which ranged between 45.53 %- 62.2% compared with inculated
and un treated control 88.86% .Without the presence of significant differences between the
bacterial treatments. Peroxidas activity on treated plants increased by Compared with untreated
plants. Seed treatments with bacteria significantly increased the plant growth. The plant height ,
fresh and dry weight of foliage, fresh and dry weight of root on treated plants were significantly
higher than those of inculated and un-treated plants according to LSD 5%.where bacteria reduced
the rate of stunting and the rate of decline mild and dry weight of foliage and mild and dry weight
of the root occurring due to infection with the Cucumber mosaic virus (CMV).
The antibacterial activity of Golden henbane (Hyoscyamus aureus) on
several species of bacteria: Pseudomonas aeruginosa, Staphylococcus
aureus and Escherichia coli was determined. Samples of H. aureus
plants were collected from six locations in southern Syria. The extract
of roots and leaves of H. aureus were prepared at concentrations.
Two bacterial species were isolated from petroleum hydrocarbon-contaminated soil.
The isolates were characterized based on their gram reaction characteristics, morphological
and biochemical properties.
The results showed two bacteria isolated the
first isolated: gram negative short rod,
urease and nitrate reduction test showed a positive result , and glucose test showed positive
result.
And the second isolated: gram positive cocci, gelatin and Citrate utilization test
showed a positive result , and maltose, mannitol test showed negative result.
They were then incubated at (37) ° C for (48- 72) hours.
This is based on comparison of results with Bergey Manual of systematic
bacteriology.
The isolates were identified to be: Pseudomonas pachastrellae (X1)
Micrococcus brunensis (X2).
Pathogenic germs have developed an increasing resistance toward many
antibiotics which form a true problem for human being ,because these germs can transport to him by
many ways such as water ,food and air that may cause many dangerous diseases to
human being.
The aim of this study is to investigate the effectiveness of extractions prepared from different parts of the
flowing plants: Olea europea Linn(Oleaceae) , Myrtus communis Linn(Liliaceae) ,Majorana syriacus
Linn (Laminaceae), Zingiber officinale Linn(Zingiberaceae),and Achillea falcata Linn(Asteraceae), against
Pseudomonas Aeruginosa.
