Pesticides (mainly herbicides, insecticides, and fungicides) are used to chemically combat certain plants, animals, or microorganisms perceived as harmful to agriculture. Due to the fundamental similarities in all living beings, it is challenging to target unwanted species without affecting others, including humans.

Endophytic microbes of medicinal plants are known to involve the synthesis of several bioactive compounds, which promote plant growth and resistance to diseases. In order to investigate endophytes in the important medicinal plant Catharanthus roseus, 16 endophytic microorganism strains were isolated from root samples of C. roseus var. roseus and C. roseus var. ocellatus naturally growing in coastal areas of Nha Trang, Vietnam.

This study aimed to isolate and identify marine fungi from Bai Tu Long Bay and assess their antimicrobial potential. We successfully isolated twenty strains of marine-derived fungi. The crude extracts from these fungi were tested against pathogenic microorganisms. All twenty strains exhibit some degree of growth inhibition against the tested microorganisms.

Although the microbiome is established as an important regulator of health and disease, the role of viruses that inhabit asymptomatic humans (collectively, the virome) is less defined. While we are still characterizing what constitutes a healthy or diseased virome, an exciting next step is to move beyond correlations and toward identification of specific viruses and their precise mechanisms of beneficial or harmful immunomodulation.

The research article "Polyester production by halophilic and halotolerant bacterial strains obtained from mangrove soil samples located in Northern Vietnam" reports halophilic and halotolerant bacteria isolated from mangrove forests located in Northern Vietnam. Several of these bacteria were able to synthesize polyhydroxyalkanoates (PHAs). PHAs are polyesters stored by microorganisms under the presence of considerable amounts of a carbon source and deficiency of other essential nutrient such as nitrogen or phosphorous.

Different types of halophiles have solved the problem how to hope with salt stress (and often with other forms of stress as well) in different ways, so that the study of microbial life at high salt concentrations can answer many basic questions on the adaptation of microorganisms to their environments. Most known halophiles are relatively easy to grow, and genera such as Halobacterium, Haloferax.

Leachate is a noticeable pollution problem because it contains a considerable amount of persistent organic pollutants (POPs). If leachate isn't treated thoroughly, its leak will negatively affect the environment. Therefore, appropriate treatment technologies are required to remove them. Bio-Electro-Fenton (BEF) is a new method using microorganisms such as electrolytes to convert chemical energy into electricity to help create H2O2 support advanced oxidation process (AOPs).

This paper presents the experimental results of the effect of microorganism fertilizer (MF) on growth, yield and accumulation of Cu in lettuce grown on soil contaminated by Cu. The results show that applying MF on soil that has a Cu content of 17.03-106.4 ppm has a positive affect on the height, fresh weight, total chlorophyll content and catalase activity of lettuce grown on that soil.

An understanding of soil microorganisms as part of soil system and interactions between the diversity of producers and of decomposers, have major consequences on the functioning of agricultural ecosystems. Soil microorganisms control the transformation and mineralization of natural compounds and xenobiotics. The soil micro biota, existing in high density and diversity, rapidly modify the energetic performance and activity rates to changing environmental conditions.

India accounts for 30% of neonatal deaths globally. Bacterial sepsis is a significant cause of morbidity and mortality in newborns. The study helps to make antibiotic policy in neonatal sepsis. The main objective is to study the incidence of multidrug resistant gram negative and gram positive organisms causing neonatal septicemia and their antibiotic sensitivity pattern. The study was conducted in the Department of Microbiology over a period of one year. Sample of blood was collected under aseptic precautions and processed by standard techniques.
