“…Bacteria introduced into soil as agents for the biological control of plant pathogens must be capable of adaptation to a hostile environment in terms of both abiotic stress and Li et al 14353 competition imposed by the resident soil microflora (Gu and Mazzola, 2001;Li et al, 2007Li et al, , 2010. Numerous studies have been conducted that have sought to enhance the efficacy of biocontrol rhizobacteria through modification of the organism or its environment to promote survival after introduction into the soil environment (Fuchs et al, 2000;Manjula and Podile, 2001;Shaukat and Siddiqui, 2003;Bae et al, 2007;Anvari, 2010). Result from this study indicated that physiological changes induced in response to nutrient limitation can alter nutritional consumption by antagonistic bacteria, which may be of benefit in a soil environment.…”

“…The success in formulating microbes depends on in vivo efficacy of the inoculum for disease control (Li et al, 2007. Indeed, the bacteria introduced into soil as agents must be capable of adaptation to a hostile environment (Gu and Mazzola, 2001;Bae et al, 2007).…”

“…It has been well known that carbon starvation mediates bacterial resistance to a number of environmental stresses (Van Overbeek et al, 1995;Gu and Mazzola, 2001;Sanin et al, 2003). In particular, several studies reported that composition of the laboratory medium used to prepare inoculum significantly influenced the biocontrol efficacy of antagonistic bacteria (Fuchs et al, 2000;Manjula and Podile, 2001;Shaukat and Siddiqui, 2003;Bae et al, 2007). The relative ability of antagonistic bacteria to grow in nutrient-limited media is also dependent upon prior culture conditions.…”

Influences of carbon adaptation on antagonistic activities of three Pseudomonas aeruginosa strains V 4 , V 7 and V 10 against Fusarium oxysporum f. sp. melonis were determined in this study. Results from this study showed that the P. aeruginosa strains and their adapted strains significantly inhibited the growth of mycelium of F. oxysporum f. sp. Melonis, while in vitro inhibition of P. aeruginosa on the mycelial growth was unaffected by carbon adaptation. In general, the growth of strain V 4 and its antagonistic ability was unaffected by carbon adaptation. However, the growth of the adapted strains V 7 -C and V 10 -C was superior to the corresponding parental strains when root exudates were used as a sole carbon source. In addition, the adapted strains V 7 -C and V 10 -C caused a more decrease in Fusarium infection of melon compared with the corresponding parental strains. Overall, this study revealed that adaptation culture of P. aeruginosa strains on carbon-limited media may play an important role in the inhibition of Fusarium wilt of melon seedlings although the effect of carbon adaptation may depend on the test strain.

“…This may be due to the production of more amounts of active compounds KS-1 and KS-2 in these two media with relatively less nutrients than other rich media. The production of antifungal compounds and biocontrol activity of the bacteria is affected by cultivation conditions specially culture media (Bae et al, 2007). An important step in the development of a biological control agent is to determine the culture media for the efficient production of high yields of viable cells without accumulation of toxic compounds to miorobes and plant growth.…”

A Bacterial Endophyte, Pseudomonas brassicacearum YC5480, Isolated from the Root of Artemisia sp. Producing Antifungal and Phytotoxic Compounds

An endophytic bacterial strain YC5480 producing antifungal and phytotoxic compounds simultaneously was isolated from the surface sterilized root of Artemisia sp. collected at Jinju area, Korea. The bacterial strain was identified as a species of Pseudomonas brassicacearum based on its 16S rRNA gene sequence analysis and physiological and biochemical characteristics. The seed germination and growth of monocot and dicot plants were inhibited by culture filtrate (1/10-strength Tryptic Soy Broth) of the strain. The germination rate of radish seeds in the culture filtrate differed in various culture media. Only 20% of radish seeds germinated in the culture media of 1/2 TSB for 5 days incubation. Mycelial growth of fungal pathogens, Colletotrichum gloeosporioides, Fusarium oxysporum and Phytophthora capsici was also inhibited by the culture filtrate of the strain YC5480. An antifungal compound, KS-1 with slight inhibitory activity of radish seed germination at 1,000 ppm and a seed germination inhibitory compound, KS-2 without suppression of fungal growth were produced simultaneously in TSB. The compounds KS-1 and KS-2 were identified to be 2,4-diacetylphloroglucinol (DAPG) and 2,4,6-trihydroxyacetophenone (THA), respectively.

“…Macro and micro elements both in natural environments and culture medium are one of the most important environmental factors. Adaptation to proper culturing medium can alter biocontrol ability and physiological state, and we must consider laboratory media in optimizing the use of biocontrol agents (Bae et al, 2007). In addition, one impediment to commercialization is the lack of liquid culture technology for inexpensive mass production and storable biocontrol agents (Slininger and Jackson, 1992).…”

Fluorescent pseudomonads are ubiquitous bacteria that are common inhabitants of the rhizosphere and are the most studied group within the genus Pseudomonas. Strain UTPF61 is a biocontrol agent against Sclerotinia wilt of sunflower, an important disease of sunflower caused by Sclerotinia sclerotiorum. This bacterium was selected out of 47 strains. It was grown in eight culture media containing different carbon sources, such as sucrose, glucose, corn steep liquor, fructose, glycerol, sugar beet molasses, manitol and starch. Our results showed that the starch has a considerable effect (P<0.01) on the rate of bacterial growth as compared to the other carbon sources used. Investigation of antifungal activity in vitro indicated that some media containing glucose and sugar beet molasses were the most effective (P<0.01) on antagonistic efficiency, whereas the medium containing sugar beet molasses was the most effective on antagonistic efficiency in greenhouse trials (with 87% healthy plants).
