Lopamudra Nayak,Siba Prasad Mishra 한국의류학회 2016 Fashion and Textiles Vol.3 No.1
Innovation in textile has brought alternative plant based fibers such as bamboo into the spotlight and as a replacement to petrochemical based synthetic fibers. Bamboo as a raw material is a remarkably sustainable and versatile resource but the manufacturing process is where the debate really gets heated and the sustainability and green image of bamboo is tarnished. Products made from bamboo are often labeled as ‘eco-friendly’, ‘bio-degradable’ and ‘anti-microbial’ irrespective of their method of manufacturing. The claims may not always portray the products authenticity and true environmental impact. By far, viscose process is predominantly used to create fibers from bamboo but the properties of natural bamboo fibers in such bamboo viscose products have been lost. However, bamboo textiles are not yet achieved their full potential and cleaner production processes are appearing. With abundant sources of raw material, relatively low cost; and unique performance of bamboo fiber it is only a matter of time to develop green and pure bamboo textiles. This paper analyses the prospects of bamboo fibers providing a view on bamboo as a plant and processed fiber, facts regarding the antimicrobial properties of bamboo fibers, its chemical properties, morphology, anatomy, historical overview, patents and modern bamboo textile industry.

Olax psittacorum (Lam.) Vahl. has versatile ethnopharmacological healing property in addition with incomplete research are adequate pieces of information to support the choice of the plant to build up proper data in acute and sub-chronic toxicological, cytotoxicity with ex vivo and in vivo antioxidant profile as well as qualitative analytical illustration through GC–MS of the selected extracts obtained from different parts of the plant. We have extracted leaf methanolic extract (LME), stem methanolic extract (SME), stem aqueous extract (SAE) and fruits aqueous extract (FrAE) for the above mentioned respective studies. OECD guideline 420 and 407, brine shrimp lethality (BSLA), lipid peroxidation, catalase assay was conducted to gather information on toxicity, cytotoxicity, and antioxidant properties respectively. BSLA study indicates that LME may be a good choice to develop as an anticancer drug for future perspective ( LC50 = 41.88 μg/ml). Both LME and SME have been selected for ex vivo and in vivo antioxidant analysis on the basis of their low toxicity and GCMS analysis. Moreover, in vivo lipidperoxidation as well as catalase assay both having significant difference (P < 0.05) between the groups except LME 200 and positive control (P = 0.084) as well as LME 200 and SME 100 (P = 0.054) respectively. This study justifies that high dose exposure of FrAE, SAE, and SME could be so toxic due to changes in biochemical parameters and in comparison, LME is safer according to the significant (P < 0.05) outcome statistically. LME and SME are safe to consume at a dose of ≤ 200 mg/kg/bw as herbal supplements with antioxidant property.

Olax psittacorum (Lam.) Vahl. (Olacaceae): current status and future prospects as an herbal plant
Majumder Raja,Adhikari Lopamudra,Dhara Moonmun 경희대학교 융합한의과학연구소 2022 Oriental Pharmacy and Experimental Medicine Vol.22 No.2
Olax psittacorum (Lam.) Vahl. traditionally used by the tribal community of ‘INDIA’ to heal conditions such as pain, psoriasis, mouth-ulcer, anemia, constipation as well as diabetes. Documented scientific shreds of evidence like antipyretic, anti-inflammatory, antimicrobial, anti-viral, anti-cancer, toxicity profile improved its medicinal value. Chromatographic evaluation (GC–MS) proven near about presence of 25 compounds. Among them, hexadecanoic methyl ester, β-sitosterol, phytol, methyl salicylate, 13-docosenamide, and oleanolic acid are significant and contribute to its successful medicinal properties. The toxicity study also revealed the safety of the consumption of the leaf part. Still, consecutive gaps need to be exploring to gather evidence of its contribution to curing different ailments, especially upon the ulcer, anemia, and identification of the presence of lead compounds as an upcoming future research proposal. The ‘Internet Scholar’, ‘Study Guide’, ‘PubMed’, ‘ScienceDirect’, ‘Scopus’, and ‘Sodhganga’ web site have been accessed to gather information about detailed scientific research as well as traditional information from authenticated sources that have been published in the English language. The various folklore claimed medicinal properties like anti-ulcer, aphthous ulcer, analgesic, anti-diabetic, anti-anemic, etc. yet to be justified scientifically with lead compounds that can support the rationality being used as folklore. This plant could be a good choice to explore its importance within the pharmacognostic field of drug development and might be a better source of herbal derived lead compounds which can help to heal ulcer or anemia that can effectively make a credible addition to treatment among the civilization as a natural source of therapeutic compounds.

A moderately halophilic spore forming, motile, Gram-positive, rod-shaped bacterial strain designated as KGW1T was isolated from water sample of Chilika Lake and characterized taxonomically using polyphasic approach. The strain grew in the presence of 0–25% (w/v) NaCl in marine salt agar media, hydrolyzes casein, and gelatin and shows presence of alkaline proteases. The major cell wall menaquinone was MK7 and major cellular fatty acids were anteiso-C15:0 (44.89%), anteiso-C17:0 (6.18%), isoC15:0 (19.38%), and iso-C16:0 (7.39%). Several chemotaxonomic features conform the isolate be a member of genus Halobacillus. The isolate KGW1T contained A1γ meso-Dpm-direct type of peptidoglycan which is different from its phylogenetically closest neighbours. The 16S rRNA gene sequence based phylogenetic analysis also revealed the strain KGW1T was affiliated to the genus Halobacillus and sequence similarity between the isolated strain and the type strains of Halobacillus species were found closest to, H. dabanensis D-8 DSM 18199T (99.08%) and H. faecis IGA7-4 DSM 21559T (99.01%), H. trueperi SL-5 DSM 10404T (98.94%). The in silico DDH showed that the values in a range of 14.2–17.5% with the most closest strain H. dabanensis D-8 DSM 18199T and other type strains of the genus Halobacillus for which whole genome sequence is reported. DNA-DNA relatedness between strain KGW1T and the closest type strain Halobacillus trueperi DSM 10404T was 11.75% (± 1.15). The draft genome sequence includes 3,683,819 bases and comprises of 3898 predicted coding sequences with a G + C content of 46.98%. Thus, the significant distinctiveness supported by phenotypic and genotypic data with its closest neighbors and other closely related species confirm the strain KGW1T to be classified as a novel species within the genus Halobacillus, for which the name Halobacillus marinus sp. nov. is proposed. The type strain is KGW1T (= DSM 29522 = JCM 30443).
