A Microbiological Approach to Alleviate Soil Replant Syndrome in Peaches

et al. 2023

Replant syndrome (RS) is a global problem characterized by reduced growth, production life, and yields of tree fruit/nut orchards. RS etiology is unclear, but repeated monoculture plantings are thought to develop a pathogenic soil microbiome. This study aimed to evaluate a biological approach that could reduce RS in peach (Prunus persica) orchards by developing a healthy soil bacteriome. Soil disinfection via autoclave followed by cover cropping and cover crop incorporation was found to distinctly alter the peach soil bacteriome but did not affect the RS etiology of RS-susceptible ‘Lovell’ peach seedlings. In contrast, non-autoclaved soil followed by cover cropping and incorporation altered the soil bacteriome to a lesser degree than autoclaving but induced significant peach growth. Non-autoclaved and autoclaved soil bacteriomes were compared to highlight bacterial taxa promoted by soil disinfection prior to growing peaches. Differential abundance shows a loss of potentially beneficial bacteria due to soil disinfection. The treatment with the highest peach biomass was non-autoclaved soil with a cover crop history of alfalfa, corn, and tomato. Beneficial bacterial species that were cultivated exclusively in the peach rhizosphere of non-autoclaved soils with a cover crop history were Paenibacillus castaneae and Bellilinea caldifistulae. In summary, the non-autoclaved soils show continuous enhancement of beneficial bacteria at each cropping phase, culminating in an enriched rhizosphere which may help alleviate RS in peaches.

Cosmetics products are the most essential and frequently used components in our daily life. Besides improving human health, they provide healthy lifestyles and boost our self-esteem. Globally cosmetics market is projected to be 287 billion USD in 2021 to 415 billion USD in 2022. This research study aims at the isolation, identification, and characterization of bacterial strains isolated from cosmetics. Six bacterial colonies were isolated by inoculating different cosmetics products on tryptic soya agar media. All the strains showed optimum growth at 37 °C. All strains were assessed through biochemical tests by using different media such as MacConkey agar, SIM, and Simmons citrate agar and were further proceeded for nucleotide sequencing through Sanger sequencing. Different bacterial strains were revealed in cosmetics products including Sphingomonas paucimobilis, Cytobacillus oceanisediminis, Robertmurraya andreesnii, Cytobacillus firmus, Falsibacillus pallidus, and Acinetobacter junii. Most of these strains were found to be pathogenic however, Sphingomonas has the potential for bioremediation and can be utilized for degrading toxic compounds to make the environment better. Similarly, Cytobacillus is found to be involved in biomineralization and also aids in fermentation. Our results have shown that there is a dire need to assure strict safety regulations regarding cosmetics. Improper manufacturing practices can lead to the contamination of cosmetics which could lead to severe consequences of deteriorating the quality of health. Further studies are needed to explore the potential of these isolates so that they can be utilized to improve our health as well as the environment.

“…This reflects the mounting interest of all disciplines besides the medical professionals for accurate and replicable microbiota profiling in diagnostic and therapeutic applications. This area has witnessed a rapid growth mainly due to huge technological advancements as well as our capabilities in understanding microbiota structure, function, their interactions with host in health and diseases ( Yadav et al., 2018 ; Yadav and Chauhan, 2021 ; Yadav and Chauhan, 2022 ). Next generation diagnostic solutions based on microbial and microbe-based diagnostic instruments as well as microbial therapeutics promises to be a mainstay in future.…”
