“…S. olivaceoviridis had a pronounced effect on yield components (spikelet number, spike length, and fresh and dry mass of the developing grain) of wheat plants. The culture filtrâtes of ail three strains appear to enhance the growth and crop yield of wheat plants (Aldesuquy et al 1998). This study lent further credence to the possibility that certain rhizobacteria, including the actinomycetes, may act as plant growth enhancers.…”

“…(S. olivaceoviridis (Preobrazhenskaya and Ryabova) Pridham et al and S. rochei Berger et al) were found to significantly increase the shoot length and shoot fresh mass, respectively, of wheat plants. Hormone extraction, purification, and bioassay showed that both species produced substantial amounts of growth-regulating substances, including auxins, gibberellins, and cytokinins (Aldesuquy et al 1998). This demonstrated that selected Streptomyces spp.…”

“…Despite the well-documented history of Streptomyces in biocontrol and preliminary évidence of their capacity to enhance plant growth (Aldesuquy et al 1998), Streptomyces species hâve been poorly investigated specifically for their potential as PGPR. This is surprising as streptomycetes, generally accounting for an abundant percentage of the soil microflora, are particularly effective colonizers of plant root Systems and are able to endure unfavorable growth conditions by forming spores (Alexander 1977).…”

“…There is very little understanding about microbial phytohormones and even less so about their effect on plant growth. Aldesuquy et al (1998) studied the effect of streptomycete culture filtrâtes on the growth of wheat plants. Shoot fresh mass, dry mass, length, and diameter ail displayed statistically significantly increases with certain strains at varying sample times.…”

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.

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

“…One of the first reports on plant growth promotion by Streptomyces (aside their biocontrol features) showed ability to increase shoot length and shoot fresh mass in wheat. Hormone analysis revealed that two strains, Streptomyces olivaceoviridis and Streptomyces rochei produce considerable amounts of auxins, gibberellins and cytokinins (Aldesuquy et al, 1998).…”

Heavy metals and metalloids removal can be considered as one of the most important world challenges because of their toxicity and direct impact on human health. Many processes have been introduced but biological processes of remediation seem to offer the most suitable solution in terms of efficiency and low cost. Actinobacteria constitute one of the major microbial populations in soil, and this can be attributed to their adaptive morphological structure as well as their exceptional metabolic power. Among microbes, actinobacteria are morphologic intermediate between fungi and bacteria. Studies on microbial diversities in metal contaminated lands have shown that actinobacteria may constitute a dominantly active microbiota in addition to α Proteobacteria. Furthermore, isolation studies have shown metal removal mechanisms which are reminiscent of notable multiresistant strains, such as Cupriavidus metallidurans. Apart from members of genus Streptomyces, which produce more than 90% of commercialized antibiotics, and the nitrogen fixing Frankia, little attention has been given to other members of this phylum. This is because of difficult culture condition requirements and maintenance. In this review, we focused on specific isolation of actinobacteria and their potential applications in metal bioremediation and plant growth promotion.
