“…Despite the above, among the advantages of the production of this fungus in liquid medium by agitated tank is the increase in the concentration of conidia in a shorter time, compared to solid fermentation in rice substrate (personal communication Juan Diego Medina 2019, unpublished data). Likewise, Sharma and others (12) pointed out how through this type of liquid fermentation some fungi achieve the production of metabolites that are dissolved in the medium. This has also been recorded by Sánchez in 2017 (22) , who demonstrated how in a liquid culture medium the UdeA0106 strain transcribes pathogenicity candidate genes, such as serine proteases, lipases and chitinases, which could explain its rapid action in just 48 hours of fungus-nematode contact in soil.…”

In vitro evaluation of the nematicide activity of the liquid fermentation of Purpureocillium sp. UdeA 0106 strain on pineapple and flower soils

Colombia is recognized as an important agricultural producer of pineapple and flowers. One of the most significant phytosanitary problems of these crops is pathogenic nematodes and it is necessary to find biocontrol alternatives for their management. This study evaluated the effect of Purpureocillium sp., strain UdeA0106, over the number of nematodes. Soil from pineapple and flower crops was collected on expanded polystyrene containers and suspension of the fungi was multiplied in a bioreactor (1x108 conidia/mL), then homogenized and finally applied. The control consisted of the containers with soil and sterile distilled water (SDW) and 4 to 6 repetitions were evaluated on each crop. The number of individuals of each genus on 100g of soil was analyzed using R studio®, Kruskal-Wallis, and van der Waals tests were applied to evaluate significant differences between strain and control (P=0.05). The results showed that the strain did not affect the saprophytic nematodes but decreased the number of Meloidogyne spp., Paratylenchus spp., Helicotylenchus spp., and Tylenchus spp; no biocontrollers had been reported before for the last two genera.

The increasing human population expected in the next decades, the growing demand of livestock products—which production requires higher amounts of feed products fabrication, the collective concern about food quality in industrialized countries together with the need to protect the fertility of soils, in particular, and the environment, in general, constitute as a whole big challenge that worldwide agriculture has to face nowadays. Some soil bacteria harbor mechanisms to promote plant growth, which include phytostimulation, nutrient mobilization, biocontrol of plant pathogens and abiotic stresses protection. These bacteria have also been proved as promoters of vegetable food quality. Therefore, these microbes, also so-called Plant Probiotic Bacteria, applied as biofertilizers in crop production, constitute an environmental friendly manner to contribute to produce the food and feed needed to sustain world population. In this review, we summarize some of the best-known mechanisms of plant probiotic bacteria to improve plant growth and develop a more sustainable agriculture.

“…have antagonist effects on phytonematodes including; (a) direct mycoparasitism which involves the production of cell-wall-degrading enzymes (Lorito et al, 2010), (b) producing chitinase into the culture or rhizoshere which might help in the inhibition of egg hatching. (Sharon et al, 2001), (c) the conidia of Trichoderma parasitize on nematode cuticle or/and egg shell (Sharon et al, 2007), (d) help plants in tolerance against stress condition by enhancing the root development through promoting to solubilization of inorganic nutrients (Sharma and Rakesh, 2009), (e) producing a variety of metabolites (mycotoxins) which inhibit egg-hatching and juveniles development (Naserinasab et al, 2011).…”

Root-knot nematodes are globally considered one of the most common phytonematodes infecting sunflower crops. In this context, current study, treatments were designed to enhancing the effect of biological control against Meloidogyne incognita by Trichoderma harzianum and Bacillus subtilis alone or in combination with antioxidant; ascorbic and salicylic acids. All treatments significantly suppressed root-knot nematode compared to control. Generally, the results indicated that the treatments of mixtures of antioxidants + bioagents showed a better response in suppression of root-knot nematode than the bioagents alone, as mixture of T. harzianum + B. subtilis gave the highest reduction in nematode population (72.3% and 80.0%).While the best synergistic effect was noticed by combination between T. harzianum and salicylic acid (74.9% and 84.9%) during the growing seasons 2018 and 2019,respectively.This positively reflected on the plant health through induction of defense related components (phenolic content and oxidative enzymes).
