Several aspects of alginate and PHB synthesis in Azotobacter vinelandii at a molecular level have been elucidated articles published during the last ten years. It is now clear that are under very complex genetic control. Genetic modification A. has produced number interesting mutants which particular traits for production. One these shown to produce with highest mean mass so far reported. Recent work also shed light on factors determining distribution; most important being identified as;...
Bacillus velezensis 83 was isolated from mango tree phyllosphere of orchards located in El Rosario, Sinaloa, México. The assessment this strain as BCA (biological control agent), well PGPB (plant growth-promoting bacteria), were demonstrated through vivo and vitro assays. In assays showed that B. able to anthracnose (Kent mangoes) efficiently chemical treatment with Captan 50 PH™ or Cupravit hidro™. inoculation the roots maize seedlings yielded an increase 12% height 45% root biomass,...
In research and production, reproducibility is a key factor, to meet high quality safety standards maintain productivity. For microbial fermentations, complex substrates media components are often used. The can vary in composition, depending on the lot manufacturing process. These variations have an immense impact results of biological cultivations. aim this work was investigate characterize influence component yeast extract cultivations Azotobacter vinelandii under microaerobic conditions....
Abstract Spore-forming Bacilli, such as the plant-associated Bacillus velezensis strains, are widely used probiotics, known for their safety and substantial health benefits both animal plant species. Through differentiation pathways mediated by quorum-sensing metabolites (QSMs), these bacteria develop multiple isogenic subpopulations with distinct phenotypes ecological functions, including motile cells, matrix-producing / cannibalistic competent spores, others. However, heterogeneity in...
To develop a pilot-plant fermentation process for the production of yeast Rhodotorula minuta, to be used as biocontrol agent mango anthracnose, using low-cost culture medium. stable liquid formulation that preserve high viability stored at 4 degrees C.Keeping constant volumetric power input, was scaled-up from shake flasks 100 l bioreactor. Preharvest applications resulted in postharvest anthracnose severity equal or lower than observed with chemical fungicide. Glycerol added water activity...
Bacillus spp. are well known plant growth promoting bacteria (PGPB) and biological control agents (BCA) due to their capacity synthesize a wide variety of phytostimulant antimicrobial compounds. B. velezensis 83 is strain marketed in Mexico as foliar biofungicide (Fungifree AB™) which has been used for five different genera phytopathogenic fungi (Colletotrichum, Erysiphe, Botrytis, Sphaerotheca, Leveillula) crops agricultural importance such mango, avocado, papaya, citrus, tomato,...
The rheological complexity of Xanthan fermentations presents an interesting problem from a mixing viewpoint, because the phenomena poor bulk blending and low oxygen mass transfer rates inherent in highly viscous (and their consequences) can be systematically investigated, even at pilot plant scale. This study 150 L fermentor compares physical biological performance four pairs impellers: standard Rushton turbine, large diameter Prochem Maxflo T, Scaba 6SRGT. Accurate in-fermentor power...
Abstract Power consumption under non‐aerated and aerated conditions was measured in a 0.45 m diameter tank containing range of xanthan gum solutions, using the Scaba 6SRGT impeller. Well‐mixed caverns were transparent Carbopol solution. The data are compared with previous results obtained Rushton turbine Reynolds numbers, Re, between 1 2000. In each case, power numbers similarly related to Re except that Po values 3 4 times smaller. Under conditions, aeration rate does not affect number, g ,...
An accurate image‐analysis method was developed to assess quantitatively the spot‐like lesions on fruits resulting from pathogen attack. The technique applied evaluation of development and severity anthracnose mango fruit, caused by fungus Colletotrichum gloeosporioides . In this method, a stepper motor rotates fruit along its longitudinal axis while acquiring sequence 360 images total surface (one image for each degree). This set is used create pseudocylindrical ‘equal‐area’ projection in...
To select Trichoderma strains for enhanced laccase production in Pleurotus ostreatus or Agaricus bisporus cultures.Laccase by P. and A. was evaluated liquid (axenic) solid (dual cultures) malt extract medium. Oxidation of ABTS, DMP syringaldazine order to assess the potential enhance basidiomycetes. Selected Pleurotus-Trichoderma interactions yielded higher increases volumetric activity an additional isoform produced. By contrast, Agaricus-Trichoderma lead smaller on activity, probably as...
Abstract Background The oxygen transfer rate (OTR) and dissolved tension (DOT) play an important role in determining alginate production its composition; however, no systematic study has been reported about the independent influence of OTR DOT. In this paper, we report a evolution molecular mass polymer produced by wild-type A. vinelandii strain ATCC 9046, terms maximum (OTR max ) cultures where was kept constant. Results results revealed that two conditions evaluated, strictly controlled...
