The genus Dunaliella is widely studied microalgae for its tolerance to extreme conditions, physiological aspects and many biotechnological applications, such as beta-carotene, protein, lipids and many other bioactive compounds. Physiological and biochemical studies are essential to fully explore the properties and possibilities of new isolates of Dunaliella.The aim of this study was to describe cellular morphology, growth rate and protein content of three Dunaliella strains, isolated from salty lakes in Mongolia. The cellular morphology, growth rates, protein contents were studied using microscopic analyses, Neubauer’s chamber, and micro kjeldahl method.Results showed that growths of all three Dunaliella cultures were progressed through lag phase at 3rd day. The growth of Dunaliella D-1 reached its peak on day 6, while Dunaliella D-6 and D-7 reached their stationary phase on day 7. Furthermore, the protein contents of dry biomass in Dunaliella D-1, D-6 and D-7 cultures were 62.2%, 36.1% and 38.15%, respectively. The highest protein content was found in Dunaliella D-1 culture, hence this culture could be used as protein rich supplement in further study.

AbstractProtein energy malnutrition (PEM) is prevalent in south-east Asian countries including India. Breeding and introduction of grain protein-rich varieties of legumes such as dolichos bean is considered as cost-effective approach to combat PEM. Exploitation of genetic variability within germplasm accessions (GAs) and/or breeding populations is the short-term strategy for identification and delivery of protein-rich dolichos bean cultivars to cater to the immediate needs of the farmers and target population. A set of 118 dolichos bean genotypes consisting of 96 GAs and 20 advanced breeding lines (ABLs) and two released varieties (RVs) was field evaluated in augmented deign for dry grain yield per plant and their grain protein contents were estimated. The grain protein content among the genotypes ranged from 18.82 to 24.5% with a mean of 21.73%. The magnitude of estimates of absolute range, standardized range, and phenotypic coefficient of variation (PCV) for grain protein content was higher among GAs than those among ABLs + RVs. However, average grain protein contents of GAs were comparable to those of ABLs + RVs. Nearly 50% of the genotypes (mostly GAs) had significantly higher grain protein content than those of RVs, HA 3 and HA 4. The grain protein contents of the genotypes were poorly correlated with grain yield per plant. These results are discussed in relation to strategies to breed grain protein-rich dolichos bean cultivars.

A new isolate was investigated from soil sample collected from Shahrasti upazilla of Chandpur district of Bangladesh. Based on the physico-chemical studies the strain was identified as gram positive Bacilli. Moleculer characterization of the strain was identified as Bacillus aryabhattai which is the first report in Bangladesh. The strain can survive in extreme conditions of salt, temperature and pH. This strain was further characterized and screened for the ability to produce useful enzymes. The optimum temperature for growth and production of these enzymes was within the temperature range 35oC to 40oC. The pH was found to be 7 for its growth and production of different enzymes when investigated over 48 h of incubation. The isolate produced various extracellular enzymes such as α-amylases, cellulases, β-glucosidases, lipases and proteases. The findings of this study provide useful information of the new strain that has potential biotechnological applications. Jahangirnagar University J. Biol. Sci. 7(2): 33-45, 2018 (December)
