“…The calcium (ca) recorded was maximum in cephalothorax 9.7 ± 10.8 and minimum in swimming and walking legs 4.3 ± 1.20 (Table 1 and Figure 6). Earlier report agreed with this study where 2157.86 ± 1.01 mg/100 g of calcium was recorded in land crab C. armatum [43], 15.670 mg/gm in P. vigil [25] and Chinese mitten crab and 0.67 mg/gm in E. sinesis [44].…”

The role of aquatic rice field species in rural diets has been underestimated. These aquatic animals potentially supply most of the protein, carbohydrate and other nutrients that are needed by the villagers. The information on nutritional composition of aquatic animal resources from rice fields is scarce since they are not common in the food baskets of most other countries. Generally marine crabs are widely used as food and feed supplements throughout the world, but people do not consider paddy fields for freshwater crabs. Although large numbers of freshwater crabs are suitable for human consumption, these aquatic animals are not consumed in large quantities elsewhere. National and regional food composition data bases contain very limited info on nutritional composition of these species. In the present study an attempt has been made to evaluate the nutritional status of the edible potamid crab The result showed that the parameters like protein, carbohydrate, lipid, moisture and ash and minerals of calcium, magnesium, potassium, sodium, iron, copper and zinc were maximum in cephalothorax and minimum in swimming and walking legs.

“…They constitute about 67% and 65% of the total amino acids in M. vollenhoveni and C. amnicola respectively and this agreed with results of the study by Babu et al [19]. The amino acid content in the two species were higher than that recorded by Bassey et al [20], Devanathan et al [21], Sudhakar et al [22] and Babu et al [19].The amino acids content of M. vollenhovenii and C. amnicola were high and this can be attributed to its omnivorous feeding habit [23] and also may be due to stress conditions caused by toxicity of heavy metals on protein metabolism [24]. The high protein concentration in crustacean species may also be due to the fact that it is the main component of the contractile elements of the striated muscles [25,26].…”

Amino acid composition of the body parts of Macrobrachium vollenhovenii and Callinectes amnicola collected from Badagry creek were assessed and determined. Fifteen and twelve samples of M. vollenhovenii and C. amnicola respectively were used in the study. The weight of the prawns ranged from 4.09g-17.50g while the crab ranged from 31.00g-119.82g. The prawns were separated into three (3) different parts which are the whole prawn, flesh and exoskeleton while the crabs were limited to the whole crab and the flesh. Chemical analysis was carried out following the modified method AOAC method 982.30, while the data obtained were analyzed using SPSS version 20.0. Eighteen amino acids were reported made up of ten (10) essential amino acids (EAA) and eight non-essential amino acids (NEAA). The EAA were arginine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine, while the NEAA were glycine, alanine, proline, aspartate, glutamate, tyrosine and cystine. The ratio of EAA: NEAA in M. vollenhovenii and C. amnicola was 1.25. There were significant differences (p=0.05) among the amino acids from the various parts analysed. Glutamate recorded the highest concentration while cystine recorded the lowest concentration in both crustaceans. Thus, these crustaceans probably play important roles in learning and sensitivity due to the concentration of glutamate which is a powerful excitatory neurotransmitter that is released by nerve cells in the brain. On the basis of nutrition and higher concentration of amino acids, M. vollenhoveni and C. amnicola are better sources of protein and can serves as substitutes for other proteinous food.Food and tissue proteins contain 20 different amino acids including essential and non-essential amino acids of nutritional importance. Shellfishes contain varying levels of high quality protein rich in all the valuable dietary essential amino acids. Amino acids are mainly obtained from proteins in diet therefore a sufficient quantity of dietary protein is required for growth, survival, development, reproduction and maintaining good health throughout life [3,4].Since amino acids have been reported to have a lot of biological importance, and prawns/crabs are regarded as good sources of proteins, this study was carried out to determine the amino acid composition of the African river prawn, Macrobrachium vollenhovenii and the crab, Callinectes amnicola from Badagry Creek, Lagos, Southwest Nigeria.

Abstract-The present investigation deals with comparative study of beta chain of the enzyme tryptophan synthase from Salmonella typhimurium and Pyrococcus furiosus. The study yielded few significant results that the sequence of beta 2 subunit (PF1706) from Pfu is closely related to the beta chain of Salmonella typhimurium in comparison to the beta 1. The phylogenetics of these two strains indicates that the beta 2 subunit plays a vital role in tryptophan synthesis in Pyrococcus furiosus. In the present investigation Salmonella typhimurium was used as a reference organism for comparative genomics of tryptophan synthase beta chain amongst a group of organisms 13 archaea and 41 proteobacteria respectively. The study reveals that most of the sequences of archaea are distantly related and was observed that there are certain sequences like pfu PF1706 which are closer to Stm that is a proteobacteria.
