Phenolic compounds of dark and clear honeys from Trás-os-Montes of Portugal were extracted with Amberlite XAD-2 and evaluated for their antioxidant and antimicrobial activities. The antioxidant effect was studied using the in vitro test capacity of scavenge the 2,2-diphenyl-1-picryhydrazyl (DPPH) free radical and of reducing power of iron (III)/ferricyanide complex. The antimicrobial activity w...

background and objectives: phosphorus is one of the low bioavailable macroelements. use of microorganisms in biofertilizers could release phosphorus from insoluble compounds. pseudomonas putida p13 and pantoea agglomerans p5 are well recognized for application as phosphate solubilizing bioinoculants and are used as solid carrier based. liquid bioinoculants are preferred for economizing producti...

Bacteriophages are widely recognized for their importance in microbial ecology and bacterial control. However, little is known about how phage polyvalence (i.e., broad host range) affects bacterial suppression and interspecies competition in environments harboring enteric pathogens and soil bacteria. Here we compare the efficacy of polyvalent phage PEf1 versus coliphage T4 in suppressing a mode...

Abstract Background Biochar ozonization was previously shown to dramatically increase its cation exchange capacity, thus improving nutrient retention capacity. The potential soil application of ozonized biochar warrants the need for a toxicity study that investigates effects on microorganisms. Results In presented here, we found filtrates collected from pine 400 and rogue did not have any inhib...

Phenol is one of the organic pollutants in various industrial wastewaters especially petrochemical and oil refining. Biological treatment is one of the considerable choices for removing of phenol present in these wastewaters. Identification of effective microbial species is considered as one of the important priorities for production of the biomass in order to achieve desirable kinetic of biolo...

To evaluate the inoculation effect of potassium releasing, phosphate solubilizing and nitrogen fixing bacteria on the fruit quality of tomato, an experiment based on randomized complete block design with 9 treatments and 3 replications has been conducted. In this experiment, tomato (super chief cv.) seedlings of the in the treasury cultivation with single and combined treatments of the potassiu...

Antimicrobial activity of methanolic, chloroform, hexane and aqueous stem extracts of Erythrina variegata L. were analyzed against nine bacterial pathogens such as Salmonella typhi, Pseudomonas putida, Pseudomonas aeruginosa, Escherichia coli, Klebsiella sp., Proteus sp., Serratia marcescens, Bacillus circulans, Staphyloccus aureus and five fungal pathogens viz. Aspergillus niger, Aspergillus f...

The bioremediation of polluted groundwater and toxic waste sites requires that bacteria come into close physical contact with pollutants. This can be accomplished by chemotaxis. Five motile strains of bacteria that use five different pathways to degrade toluene were tested for their ability to detect and swim towards this pollutant. Three of the five strains (Pseudomonas putida F1, Ralstonia pi...

A study to attain healthy tomato (Lycopersicon esculentum Mill) seedlings through environment-friendly natural biological products took place from January March 2022. Determining the effects of inoculum prepared five plant growth-promoting rhizobacteria (PGPR) isolates, i.e., Pseudomonas fluorescens, putida, Lysinibacillus fusiformis, Enterobacter cloacae, and Kineococcus radiotolerans on produ...
