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 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.

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).

The sea is a unique ecosystem for finding secondary metabolites from marine microorganisms. Many compounds produced by marine microorganisms with antibacterial activity have been applied in life. Furthermore, microorganisms are renewable raw materials and media for drug production, thus crucial for sustainable development in our life.

In this study, the synthesis of dimeric disulfide-Schiff bases was carried out using two methods. The structures of the obtained Schiff bases were elucidated by various spectroscopic methods as well as elemental analysis. The Schiff base derivative compounds (3a-6) were screened for in vitro antibacterial activity against multidrug-resistant microorganisms using microdilution method. All the tested compounds showed varying inhibition zones against the pathogens.

The present study intended to investigate the effect of aqueous extract from Calotropis procera L. on growth of wheat (Triticum aestivum L.), barley (Hordeum vulgare L.) and some pathogenic microorganisms (Escherichia coli L. and Staphylococcus aureus R.) by the laboratory experiments. Also, phytochemical screening of aqueous extract of C. procera was qualitatively tested for the presence of some bioactive compounds (alkaloids, phenolics, flavonoids, tannins, saponins, sterols and terpenoids).

The newly synthesized compounds were screened for their antimicrobial activities; some of them were found to be active towards the test microorganisms as the results demonstrated that the synthesized compounds exhibited a broad spectrum of activity with minimum inhibitory concentration (MIC) values of 31.3–500 µg/mL against gram-positive and gram-negative bacteria, Candia albicans and Saccharomyces cerevisiae.

Detection of bacteria using antimicrobial polymer derived via ring-opening metathesis (romp) pathway
There is growing interest in the detection of bacteria in consumables, for example, in the food and water sectors. In this study, the aim was to produce a polymer-based bacteria biosensor via ROMP (ring opening metathesis polymerization). In the first part of the study, block and random copolymers were synthesized, and their biocidal activities were tested on the glass surface. Interdigitated electrode arrays coated with the polymers possessing the highest activity were used to screen the affinity towards different bacterial strains by monitoring impedance variations in real-time.

In the present study collected twenty (20) direct sown paddy rhizosphere soil samples from four districts of Andhra Pradesh and recorded their geographical position of collected soil samples. From that thirty two (32) Zinc Solubilizing Bacteria (ZnSB) isolated by using zinc phosphate [Zn3(PO4)2] as a insoluble source of zinc in the trismineral salts media. Zinc solubilizing isolates coded based on their soil sample collected geographical position, recorded the morphological, cultural characteristics of ZnSB.

Phragmites australis, common pond reed with high lignocelluloses content is suitable for bioethanol production. In the present study pretreated pond reed was first fermented to sugars using cellulose and xylan degrading microorganisms isolated from cow dung and organic kitchen waste. Further fermentation of sugars to ethanol was performed using combinations of Sachharomyces cerevisae, Trichoderma reesei and Pichia stipitis.

Lipases are secreted by many fungi, yeasts and bacteria. The suitable habitat to isolate lipase producing microorganisms is the oil contaminated sites. In Ujjain a very famous „Navgrah-Shani‟ Temple situated at the Triveni Ghat of Kshipra river, where devotees from all over India come and worship the lord and it is an unique oily habitat for isolation of lipase producing microorganisms. The present study was aimed to isolate, screen and identify the lipase producing fungi from the oil contaminated soil.

The objective of this study is to isolate and screen fungal strains with antibacterial activity from the marine environment. Twenty five strains of fungi were isolated from marine sediments of Thanh Lan, Co To island and assessed on antibiotic activity against 7 tested microbial strains, including three Gram-negative bacteria (Escherichia coli ATCC25922, Pseudomonas aeruginosa ATCC27853, Salmonella enterica ATCC13076), three Gram-positive bacteria (Enterococcus faecalis ATCC29212, Stapphylococus aureus ATCC25923, Bacillus cereus ATCC 13245), and the yeast Candida albicans ATCC10231.

The transformation of cereals and tubers with amylolytic fermentation allows the conservation of foods and increase their energetic and nutritional values. The aim of this work was to search fermentative strains with amylolytic potentials. Isolation of microbial flora on 45 samples of fermented foods (agbelima, eblima and epoma) was performed. The search of microorganisms producing amylases was realized on appropriate culture media combined with 1 % of soluble starch.
