1RESUMO -Este trabalho teve como objetivos isolar e selecionar rizobactérias promotoras do crescimento de P. taeda. O isolamento foi realizado a partir de mudas com 150 dias de idade, realizando-se a seleção por meio da inoculação dos isolados (10 8 u.f.c mL -1 ) na proporção de 0,1 mL de inóculo.cm -3 de substrato. Aos 150 dias de semeadura, avaliaram-se as seguintes variáveis: altura da parte aérea, diâmetro do coleto e pesos de matéria seca de raízes e da parte aérea. Entre 99 isolados testados em P. taeda, apenas seis (UFV-AL9, UFV-AM5, UFV-AM2, UFV-F3, UFV-G2 e UFV-G4) destacaram-se quanto à indução de crescimento e ao melhor índice de qualidade de muda. Não se observaram diferenças significativas entre a testemunha e os demais isolados testados.Palavras-chave: Pinu, Rizobactérias e Qualidade de mudas.

“…The key to the concept of root colonization is that rootcolonizing bacteria grow on roots in the présence of the indigenous microflora (Schroth and Hancock 1982) and thus root colonists are compétitive with soil bacteria and fungi. While we prefer to use the term root colonization, other terms hâve been proposed.…”

Les actinomycètes représentent une grande proportion de la biomasse microbienne du sol et ont la capacité de produire une large variété d’antibiotiques et d’enzymes extracellulaires. Plusieurs souches d’actinomycètes s’avèrent capables de protéger les plantes contre des maladies. Cette revue se penche sur le potentiel des actinomycètes comme (a) source de composés agronomiques, (b) agents stimulant la croissance des plantes et (c) agents de lutte biologique. La revue donne aussi des exemples de lutte biologique contre les agents phytopathogènes bactériens et fongiques par l’utilisation d’espèces d’actinomycetes déjà disponibles sur le marché ou qui le seront probablement au cours des prochaines années.Actinomycetes represent a high proportion of the soil microbial biomass and have the capacity to produce a wide variety of antibiotics and of extracellular enzymes. Several strains of actinomycetes have been found to protect plants against plant diseases. This review focuses on the potential of actinomycetes as (a) source of agroactive compounds, (b) plant growth promoting organisms, and (c) biocontrol tools of plant diseases. This review also addresses examples of biological control of fungal and bacterial plant pathogens by actinomycetes species which have already reached the market or are likely to be exploited commercially within the next few years

A rhizobacterium LPN-2, which showed strong antifungal activity and auxin producing ability, was isolated from a farmland in North Gyeongsang Province, South Korea. Based on analysis of the 16S rDNA sequence, strain LPN-2 was identified as a novel strain of Burkholderia and was designated as Burkholderia sp. LPN-2. In vitro experiments showed that the isolated stain LPN-2 significantly produced auxin within 48 hr incubation. In order to check for PGPR function we performed in vivo growth promoting test in different crops, including mung bean, pea and cabbage. Application of Burkholderia sp. LPN-2 showed dramatic growth promoting effect on all the tested plants. We also confirmed siderophore and cellulase productions by Burkholderia sp. LPN-2 using CAS blue agar and CMC plate test. Further treatment with LPN-2 and the crude culture broth was effective in suppressing anthracnose in vitro test and also reduced incidence and severity of anthracnose in apple and pepper. Taken together, we conclude that Burkholderia sp. LPN-2 might be used as organic fertilizer for effective crop production in organic farming.
