In the present paper, altogether three algal taxa of genus Bulbochaete C. Ag. (Oedogoniales, Chlorophyceae) viz. Bulbochaete elatior f. pumila Hirn, Bulbochaete pseudoelatior Jao and Bulbochaete triangularis var. bengalensis J.P. Keshri have been morpho-taxonomically described with physico-chemical characterization of water and some additional information. These algal samples were collected as epiphytic conditions on submerged stems of angiospermic plants from two freshwater ponds in Hooghly district, West Bengal, India. All these three species are new records from this region. They were greenish, nannandrous, gynandrosporous or idioandrosporous. Most importantly, phenotypically their oospore shape was more or less alike as oogonium. The results of analyses of physico-chemical parameters of water showed that pH ranged from 7.2-7.4 (alkaline). The primary nutrients like nitrate-nitrogen (NO3-N) and phosphate (PO43-) values were measured in lower amounts (0.15-0.17 mg/l and 0.23-0.24 mg/l, respectively) which affected Bulbochaete growth and diversity in the lentic water bodies. It was interesting to note that winter season was suitable for their occurrences.ECOPRINT 23: 13-18, 2016

Silico Analysis

Sandalwood is a commercially and culturally important plant species belonging to the family Santalaceae and the genus Santalum. In Indian sandalwood is renowned for its oil, which is highly rated for its sweet, fragrant, persistent aroma and the fixative property which is highly demanded by the perfume industry. For better production and varieties, requires to understanding the functions of proteins, their analysis and characterization of proteins sequences and their structures, their localizations in cell and their interaction with other functional partner. Due to limited number of in silico studies on sandalwood, in the present study we have performed in silico analysis by characterization of sandalwood proteins. Total 23 proteins were obtained and characterization using UniProtKB, identifying their physico-chemical parameters using ProtParam tool and prediction of their secondary structure elements using GOR of all 23 proteins.

Multiple Variables

A study on diversity, seasonal occurrence, distribution percentage of microalgal taxa and physico-chemical parameters of five community ponds, located in Chinsurah town, Hooghly district of West Bengal, has been carried out. Correlation between occurrence of microalgal genera and some parameters of environment, physico-chemical nature of natural water bodies were explored by Canonical Correspondence Analysis (CCA). Diversity indices have been calculated using PAST software program. A total of 23 microalgal taxa belonging to four algal classes were recorded and the study indicated that the microalgal diversity vary with variation in physico-chemical parameters of water and light intensity. Out of these genera, occurrence of Chodatella sp. in late summer and Tetrallantos sp. and Synechocystis sp. in winter season were specific. In CCA, multiple variables (dissolved oxygen, water temperature, electrical conductivity, pH, light intensity and inorganic phosphorous) played a significant role in occurrence of microalgal taxa. Observation concluded that the Chlorophycean members were dominant throughout the study period and the Shannon–Wiener diversity index was highest for a site with large number of Chlorophycean member. This study will help in future to assess water quality.

Physico Chemical

Samples of Spanish dry-cured hams were analyzed using several physico-chemical parameters (moisture content, chlorides, water activity, nitrate, nitrite, total volatile basic nitrogen [TVBN], pH, and oxidation-reduction potential [Eh]). The samples (n = 76) were taken from three basic types of dry-cured hams produced in Spain: slow-cured hams from white pigs (n = 39), fast-cured hams from white pigs (n = 15), and hams from black-skinned Iberian pigs (n = 22). Overall, 56 samples (73.7%) showed the “bone taint” condition, and the remaining 20 hams (26.3%) were normal, and therefore considered as a control group. The objective of this research was to establish the possible circumstances that determine the alteration by means of the differences found in the values of the analyzed measurements in both groups of samples (altered versus normal ones). The hams with “bone taint” were, in general terms, those with a higher TVBN content, a greater pH, and a lower Eh, attributable to an anomalous development of the proteolytic phenomena. The conjunction of a lower concentration of chlorides, greater moisture content, and a higher aw in the affected hams may have created the conditions favorable for tissue enzyme and/or microbial activity.
