“…We also showed that mature composts amended with chitin residues acquired suppressive properties against several plant pathogens (Côté et al 2001;Labrie et al 2001;Roy et al 1997). In thèse suppressive composts, the microbial population is characterized by a prolifération of Gram-positive bacteria belonging mainly to the bacterial group of actinomycetes (Labrie et al 2001).…”

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

“…Chitin is a poly (N-acetyl-D-glucosamine) insoluble in water and in most organic solvents because of strong H bonds between polymer chains (Flores et al 2006). However, the oligomeric chitin formed during composting is water soluble and easily hydrolyzed (Roy et al 1997;Labrie et al 2001). Because crab and shrimp wastes had been composted, any chitin residue could be assumed to be negligible in our composts.…”

Lignin plus cutin (LIC) content and biological stability index (BSI) are well-recognized indexes of potentially recalcitrant carbon (C) in organic products, and C / nitrogen (N) and lignin/N ratios have been related to potentially mineralizable N (PMN).Our objective was to use Fourier-transform near-infrared (FT-NIR) spectroscopy to estimate PMN and BSI of plant residues, composts, and manures. We also evaluated FT-NIR for determining the C/N, LIC/N, and BSI/N ratios as indexes of N mineralization in selected organic products. We analyzed 148 organic products for biochemical composition and total C and N. A subset of 10 products was incubated in a sandy soil to determine PMN. The FT-NIR successfully determined lignin and cutin (LIC) and BSI from r 2 , the ratio of prediction to standard deviation, and the ratio error range criteria. The PMN was less closely related to the C/N ratio (r 2 = 0.64) than the BSI/N (r 2 = 0.84) and LIC/N (r 2 = 0.87) ratios. There was some N immobilization at an early stage of incubation when C/N, LIC/N, and BSI/N ratios exceeded 14, 10, and 15, respectively. There is a need to characterize a larger number of organic compounds in the soluble and LIC fractions to improve the BSI equation.

“…Vỏ tôm là bộ xương ngoài, một cái áo giáp để bảo vệ cơ thịt của tôm khỏi động vật ăn thịt và mầm bệnh, nó cũng giúp giữ cơ thể mềm trong hình dạng con tôm. Cấu tạo của vỏ tôm gồm 04 phân lớp chính, thành phần bao gồm canxi, chitosan, chitin, carotenoproten và nhiều loại khoáng chất [3]. Canxi chiếm thành phần chính và có giá trị kinh tế cao, đặc biệt canxi hữu cơ, chitosan, chitin và carotenoproten cũng là những thành phần có giá trị kinh tế cao và ứng dụng trong nhiều lĩnh vực như y tế [4], thẩm mĩ, nông nghiệp [5][6][7], thực phẩm [8][9][10][11].…”

In this study, the author mixed peeled shrimp shells in intensive shrimp farming and straw with probiotics using the aerobic organic composting process to produce calciumrich organic fertilizer. After 50 days of composting of peeled shrimp shells and straw with BioUSD or Fito-Biomix RR probiotics, the resulting fertilizer was brown-black in color, highly soft, spongy and highly degraded and has a relatively uniform size. Due to the action of microorganisms in Bio-USD probiotics, the nutritional compositions in peeled shrimp shell fertilizer had total nitrogen 4.34%, NH4+-N 269 (mg/kg), total carbon 14.6%, organic matter 51.3%, total calcium 22.0%, and C/N ratio 3.26. Similarly, the nutritional compositions in that fertilizer by FitoBiomix RR probiotics were total nitrogen 4.17%, NH4+-N 329 (mg/kg), total carbon 17.8%, organic matter 53.8%, total calcium 17.8%, and C/N ratio 4.27. Finally, the author evaluated the quality of the fertilizers with different probiotics in bok choy cultivation.
