ABSTRAK. Penelitian ini bertujuan mengetahui jenis bakteri Gram negatif pada uterus sapi Aceh yang mengalami kawin berulang. Dalam penelitian ini digunakan enam ekor sapi Aceh betina yang terdiri atas tiga ekor sapi fertil (K1) dan tiga ekor yang mengalami kawin berulang (K2, repeat breeding, RB). Pengambilan sampel bakteri dalam uterus sapi dilakukan dengan menggunakan swab steril yang disimpan dalam media nutrient broth (NB) untuk isolasi dan identifikasi jenis bakterinya. Berdasarkan hasil penelitian, baik K1 dan K2, positif terinfeksi bakteri dan diperoleh 16 isolat bakteri di antaranya enam isolat berasal dari K1 dan sepuluh isolat berasal dari K2. Dari 10 isolat bakteri Gram negatif yang ditemukan pada sapi RB terdiri atas Escherichia coli (E. coli) (30,00%), Pseudomonas sp. (30,00%), Enterobacter sp. (20,00%), Klebsiella sp. (20,00%). Disimpulkan bahwa bakteri yang paling banyak menginfeksi uterus sapi RB adalah E. coli dan Pseudomonas sp. (Isolation and identification of gram negative bacteria in uterine Aceh cow with repeat breeding) ABSTRACT. The study determined the type of Gram negative bacteria of the Aceh cattle uterus which has been diagnosed with repeat breeding. The study was conducted on six Aceh cows consists of 3 normal fertile cows (K1) and 3 repeat breeding cows (K2, RB). The bacteria in uterine samples were collected using sterile swab, kept into nutrient broth (NB) for further isolation and identification of bacteria. The result of the study showed that the total of 16 isolates of bacteria was observed in all cows : 6 isolates from group K1 and 10 isolates from group K2. A total of 10 isolates from cattle with repeat breeding consist of Escherichia coli (E. coli) (30.00%), Pseudomonas sp (30.00%), Enterobacter sp (20.0%), and Klebsiella sp (20.0%). It can be concluded that the most bacteria that infect uterine cows with repeat breeding are E. coli and Pseudomonas sp.

Seven strains of microorganisms out of 35 examined produced pantothenic acid. These included 3 strains of Bacillus licheniformis, 3 strains of Enterobacter cloacae and 1 strain of Hansenula subpelliculosa. Microorganisms not producing pantothenic acid included: Streptococcus faecalis, Lactobacillus brevis, Moraxella sp., Pseudomonas sp. and Agrobacterium spp. The non-producers could not use B-alanine or pantoyl lactone or a combination of the two molecules which constitute pantothenic acid. Addition of sucrose (2%) to the nutrient broth reduced pantothenic acid production by about 68%. Control corn meal contained 0.44±0.02 mg pantothenic acid/100 g, whereas fermented corn meal contained 1.84±0.16 mg/100 g after 3 d and 1.48±0.5 mg/100 g after 5 d of fermentation.

A Pseudomonas sp. 102 strain, which is highly resistant to toxic effects of cadmium and has plant growth-promoting activity, can significantly increase growth parameters and biomass of tomato plants, including those observed under toxic effects of cadmium. The greatest positive effect was observed in plants transformed with the bacterial adhesin gene rapA1, the product of which is important for colonization of plant roots by bacteria. It was also shown that shoots of transgenic tomato plants accumulated the greatest amount of cadmium during inoculation with Pseudomonas sp. 102. The ability to extract high concentrations of cadmium and accumulate a large biomass under stress opens up prospects for the further use of associative interactions between tomato and Pseudomonas for phytoremediation. phytoremediation, cadmium, tomato, Pseudomonas, inoculation, agglutinins, This study was carried out using the equipment of the Biomika Centre for Collective Use of the Institute of Biochemistry and Genetics (Ufa Federal Research Centre, Russian Academy of Sciences) as part of the government task (project no. AAAA-A16-1160203500284). This study was supported by the Russian Foundation for Basic Research (project nos. 18-34-20004 and 18-34-00033) and 18-344-0033 mol_a_ved and 34-00033 mol_a).
