Opis:: Endophytes are an important constituent of sustainable agriculture because of their ability to produce a large number of agriculturally important metabolites. A salt-tolerant fluorescent green pigment-producing endophytic bacterium was isolated on 2.5% NaCl-supplemented nutrient agar from the leaf samples of Zanthoxylum alatum Roxb. The isolate Z1B4 was identified as Pseudomonas fluorescens based on morphological features, fatty acid methyl ester analysis, biochemical tests, and 16S rRNA gene sequencing. P. fluorescens Z1B4 showed positive results for tricalcium phosphate solubilization; 1-aminocyclopropane-1-carboxylate (ACC) deaminase activity; and production of auxins, siderophores, hydrogen cyanide, and ammonia. P. fluorescens Z1B4 also showed strong antagonistic activity against Curvularia lunata (MTCC 283), Fusarium verticillioides (MTCC 3322), and Alternaria alternata (MTCC 1362) and exhibited stress tolerance to a wide range of temperature and pH and concentrations of NaCl and calcium salts. Under natural conditions, following inoculation with the isolate Z1B4, a significant increase in the growth of pea and maize test plants in pots was observed compared to that of uninoculated control plants. The rifampicin-resistant mutant Z1B4Rif was recovered from the roots, shoots, and leaves of the test plants, indicating that the isolated endophytic bacterium can grow well within different plant tissues. The present study indicated that the endophytic bacterium P. fluorescens Z1B4 can be used as a bacterial inoculant in stressed environments for sustainable agriculture.

Opis:: Phytate-mineralizing bacteria (PMB) with plant growth-promoting activity can be considered as a potential biofertilizer for plant nutrition. PMB catalyzes the conversion of insoluble sugar phosphates, inositols, nucleic acids, phospholipids, nucleotides, phytate, and phytin into soluble forms that can be assimilated by plants. The present study aimed to isolate potential PMB from rhizospheric soils and to study their plant growth-promoting potential for the possible development of a potential phosphobacterium biofertilizer. For this purpose, 34 PMB isolates were isolated that showed potent phytate-mineralizing potential. These isolates were tested for their potential to solubilize tricalcium phosphate (TCP) and for various other plant growth-promoting activities. Significant differences were found among the isolates with regard to phytate mineralization and other plant growth-promoting characteristics. The bacterial isolates biochemically identified as Bacillus, Paenibacillus, Arthrobacter, and Burkholderia exhibited high/medium P solubilization, medium/high phytohormone production, and medium/low siderophore and ammonia production. Among all these isolates, isolate A14 (Burkholderia cenocepacia strain FDAARGOS_7) was the promising isolate with high TCP solubilization, medium phytate mineralization, high enzyme production, medium/high phytohormone production, and medium ammonia production. This strain also showed nitrogen fixation activity, zinc solubilizing potential, potassium solubilization, ACC deaminase production, and catalase production. Hence, it can be concluded that B. cenocepacia can be the potential candidate for biofertilizer development. Future studies are planned for exploring the role of PMB in biofertilizer formulations.

Opis:: Biological control of plant diseases is strongly emerging as an effective alternative to the use of chemical pesticides and fungicides. Stress tolerance is an important attribute in the selection of bacteria for the development of microbial inoculants. Fourteen salt-tolerant bacteria showing different morphological features isolated from the rhizosphere of maize were evaluated for different plant growth-promoting activities. All isolates showed auxin production ranging from 5 to 24 μg ⋅ ml–1 after 48 h incubation in tryptophan supplemented media. Phosphate solubilization ranged from 15 to 419 μg ⋅ ml–1. 1-aminocycloproprane- 1-carboxylate (ACC) deaminase activity was shown by 6 isolates, ammonia production by 9 isolates, siderophore production by 8 isolates while HCN production by 4 isolates. Four bacterial isolates with all plant growth-promoting properties also showed strong antagonistic activities against Fusarium oxysporum, F. verticillioides, Curvularia lunata and Alternaria alternata and abiotic stress tolerance against salinity, temperature, pH and calcium salts. Two selected bacterial isolates significantly enhanced the growth of pea and maize test plants under greenhouse conditions. The bacterial isolate M1B2, which showed the highest growth promotion of test plants, was identified as Bacillus sp. based on phenotypic and 16S rDNA gene sequencing. The results indicated that Bacillus sp. M1B2 is a potential candidate for the development of microbial inoculants in stressful environments.

Opis:: Badano sezonowe zmiany liczebności bakterii mineralizujących lecytynę i rozpuszczających fosforan trójwapniowy w wodzie, glebie ryzosferowej turzycy błotnej (Carex acutiformis Ehrh.), na powierzchni zanurzonych w wodzie i wynurzonych częściach tej rośliny oraz jej korzeniach (obumarłych i żywych). Badania przeprowadzono w dwóch kolejnych cyklach rocznych (w latach 1993 i 1994). Stwierdzono małą liczebność badanych grup drobnoustrojów w wodzie, większą na zanurzonych w niej częściach rośliny, największą w glebie ryzosferowej i poza ryzosferą. W cyklu rocznym większa liczba drobnoustrojów występowała w miesiącach letnich, wyjątkowo jesienią. Obie badane grupy drobnoustrojów stanowiły znikomy procent ogólnej liczby bakterii heterotroficznych, oznaczanych na podłożu z tryptonem, glukozą i ekstraktem drożdżowym. Stosunek liczbowy bakterii mineralizujących lecytynę na korzeniach turzycy błotnej i bakterii występujących w glebie ryzosferowej wynosił od 0,05 do 4,5, a bakterii rozpuszczających fosforan trójwapniowy w obu tych ekosystemach od 0,2 do 4,4.
Seasonal changes in the numbers of lecithin-mineralizing and tricalcium phosphate-dissolving bacteria in water, soil, on the sedge (Carex acutiformis Ehrh.) surfaces immersed in water, on its leaves and roots (dead and alive) were studied. The study was carried out in two annual cycles (in 1993 and 1994). Low numbers of studied groups of microorganisms were found in water, higher on the surface of submerged parts of plants and the highest in the soil in and outside the rhizosphere. In the annual cycle, bacteria were most numerous in summer and present only exceptionally in the autumn months. Both studied groups of bacteria constituted negligible part of the total number of heterotrophic bacteria. The ratio of lecithin-mineralizing bacteria in the rhizosphere to those oustside the plant rhizosphere ranged from 0.05 to 4.5. Respective proportion of tribasic calcium phosphatesolubilizing bacteria in both sites ranged from 0.2 to 4.4.
