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.

The methanol extracts as well as some compounds from this plant exhibited anti-inflammatory, antimicrobial activity, antioxidant, hepatoprotective and anti-cancer effect, and antiosteoporotic. On going to search for bioactive components from the Vietnamese plant, this paper reported the isolation of seven phenolic compounds including one new from the aerial parts of A. ilicifolius. The cytotoxic activity of the isolates against two cancer cell lines (HepG2 and SK-LU1) were also screened and reported herein.

In this paper, seventy-two yeast strains isolated from natural honey and beeswax in Son La were screened for the ability of alcoholic fermentation to produce mead. Screening yeast strains for low-alcohol mead production were carried out based on the fermentation ability and the sensory of the final mead product.

Feathers cause environmental problems worldwide when poultry processing industries produce it as a waste of billions of tons yearly. This waste is not easily decomposed by natural agents in a short time. Currently, Streptomyces spp. are known as a highly enzymatic activity species which can efficiently degrade feathers to products. Therefore, the aim of this study was to screen for Streptomyces strains with high feather-degrading activity.

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.

As a continuation of our work on the bioactive constituents from Caesalpinia species, eight compounds (1−8) were isolated from the air-dried leaves of C. bonduc, collected from Vinh Phuc province of Vietnam. The cytotoxic activity of eight compounds (1–8) was screened on HepG2 human cancerous cells using the sulforhodamine B colorimetric assay.

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).

Lactic acid, which can be produced by many bacterial groups through fermentation, is an interesting compound because it can be used in various fields such as in the food, pharmaceutical, material and chemical industries. In the present study, eight high lactic acid producing bacteria were isolated and screened from fermented mustard greens. The highest lactic acid producer (strain V156) was selected for further studies.
