Currently, L-asparaginase isolated from terrestrial microorganisms has been employed for anticancer industrial production. This enzyme has the function of inhibiting the growth of acute lymphoblastic leukemia, Hodgkin's lymphomas and other cancers. In this study, for the first time, L-asparaginase (ASNase) productive capacity of forty marine bacteria originating from Khanh Hoa sea of Viet Nam was screened and reported.

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.

Polysaccharide monooxygenases (PMOs) and Glycoside Hydrolases (GH) play a crucial role in breaking down chitin and cellulose. Research on PMOs has mainly focused on their role in the production of bioethanol from biomass. Still, the potential of PMOs as virulence factors in microorganisms is not been fully studied.

The marine environmental conditions are particularly different from terrestrial ones; recent studies have showed that marine actinomycetes might produce many novel compounds with good biological activity. The objective of this study is to isolate and screen actinomycetes strains from the marine environment with activity against pathogenic microorganisms.

Streptomyces are considered the most potential microbes with the ability to produce antimicrobial and anticancer agents. These bacteria are found mostly in soil across the globe and play a pivotal role in material recycling processes. Isolation of Streptomyces in Vietnam has been conducted for years.

The rhizosphere microorganisms can form beneficial, pathogenic, or neutral relationships. These relationships can promote plant growth and productivity. Among them, a number of Variovorax isolates from the rhizosphere were isolated. Bacteria Variovorax strain C6d (AB552893) was isolated from the non axenic culture of Chlorella spp., C6.

The results showed that 02 bacterial strains and 06 actinomycete strains were selected from 32 isolates. Then, we optimized the growing conditions of the screened microorganisms. Among actinomycetes strains PU1.1, PU2.1 gave the highest weight loss results, therefore they were selected for further study. Our results showed that TG2.1 and CM4.1 are Bacillus subtilis. PU1.1 is Streptomyces lilacs, while PU1.2 is Streptomyces Misiones. The selected microorganisms belong to risk group level 1 (safety group).

While current trends in Green Analytical Chemistry aim at reducing or simplifying sample treatment, food usually comprises complex matrices where direct analysis is not possible in most cases. In this context, sample treatment plays a pivotal role. Biogenic amines are naturally formed in many foodstuffs due to the action of microorganisms, while their presence has been associated with adverse health effects.

Converting spent mushroom substrates into organic fertilizer helps to tackle the problem of pollution in edible canna starch processing villages and adds new value to the production chain of edible canna. To successfully turn the spent substrates into compost, there is certainly an indispensable role for cellulolytic microorganisms, in which Bacillus strains are always important.

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.

A review of current knowledge and gaps about campylobacter methods: From culture to characterization
The frequency of these microorganisms in poultry is fairly high than Salmonella and more challenging to measure, which represent an expensive burden charge on public health due to their difficulties to master them, especially with the fast increase rates of multidrug-resistant of thermophilic Campylobacter strains. It is well recognized that Campylobacter spp. is a fastidious cell, difficult to isolate in laboratories owing to their requirements and sensibility.

The isolates were checked for the probiotic properties such as antimicrobical production, pH & temperature tolerance, NaCl tolerance, cell adhesion, bile tolerance and cholesterol removal. Initially, twelve yeasts were isolated from each of the three different sources and characterization tests were performed.

Marine bacteriophages play key roles in the community structure of microorganisms, biogeochemical cycles, and the mediation of genetic diversity through horizontal gene transfer. Recently, traditional isolation methods, complemented by high-throughput sequencing metagenomics technology, have greatly increased our understanding of the diversity of bacteriophages. Oceanospirillum, within the order Oceanospirillales, are important symbiotic marine bacteria associated with hydrocarbon degradation and algal blooms, especially in polar regions.

Nicotine-degrading microorganisms (NDMs) have recently received much attention since they can consume nicotine as carbon and nitrogen source for growth. In our previous work, we isolated an efficient nicotine-degrading fungus Aspergillus oryzae 112822 and first proposed a novel demethylation pathway of nicotine degradation in fungi.

Houseflies (Musca domestica L.) live in intimate association with numerous microorganisms and is a vector of human pathogens. In temperate areas, houseflies will overwinter in environments constructed by humans and recolonize surrounding areas in early summer. However, the dispersal patterns and associated bacteria across season and location are unclear.
