Studies on the Fungi in Stored Rice
Mheen, T.I.,Cheigh, H.S.,Ragunathan, A.N.,Majumder, K.S. 한국미생물 · 생명공학회 1982 한국미생물·생명공학회지 Vol.10 No.3
미곡저장중 균류에 의한 미곡의 손실을 방지하기 위하여 1978년 12월 부터 1979년 6월까지 7개월간 싸일로, 평창고 및 통가리에 저장한 미곡시료(밀양23호)에서 균류를 분리, 동정하였다. 한국산 벼 및 현미에서 분리된 30종의 균류중, Aspergillus속 11종(A. caespitosus, A. condidus, A. chevalieri, A fischeri, A. fumigatus, A. fiavus, A. nidulans, A. oryzae, A. ruber, A. sydowii, A. versicolor), Penicillium 속 5 종 (P. atramentosum P. chrysogenum, P. cyaneofulvum, P. nototum, P. steckii), Alternaria 속 2종 (Al. faesiculata, Al. grisea) Curvalaria 속 2종 (C, interseminata, C. tetromea), Trichothecium roseum, Nigrospora sphaerica, Rhizopus nigricans, Fusarium spp., Mucor spp., Helminthosporium spp., 및 Gliocladiopsis spp. 각 1종, 총 27종이 동정, 확인되었다. 한국산 벼에서 분리된 표면균류는 A. flavus와 A. candidus가 대부분이었으며, 현미에서는 A. sydowii가 많이 출현하였다. 또한 저장중 변질미에는 A. candidus, A. versicolor 및 A. glaucus group들이 주로 많았다. In order to prevent the losses of the rice by fungal deterioration during storage, fungal contaminants were isolated and identified from the grain samples (Milyang Nr.23) stored for seven months from December, 1978 to June, 1979 in silo, flat store and Tongari. Out of thirty cultures isolated from Korean paddy and brown rice samples, twenty seven species were identified, and there are eleven species of Aspergillus (A. caespitosus, A. condidus, A. chevalieri, A fischeri, A. fumigatus, A. flavus, A. nidulans, A. oryzae, A. ruber, A. sydowii, A. versicolor), five species of Penicillium (P. atramentosum, p. chrysogenum, P. cyaneofulvum, P. nototum, P. steckii), two species of each Alternaria (Al. faesiculata, Al. grisea) and Curvalaria (C, interseminata, C. tetromea), and one species of each Trichothecium roseum, Nigrospora sphaerica, Rhizopus nigricans, Fusarium spp., Mucor spp., Helminthosporium spp., and Gliocladiopsis spp. The major types of fungi grown on the surface of paddy during storage were A. flavus and A. candidus, while A. ruber and A. sydowii appeared in brown rice samples. And also A. candidus, A. versicolor and A. glacus groups were considered as major deteriorating microorganisms in stored brown and paddy rice in Korea.

Completeness and compactness in fuzzy cone metric spaces
A. Majumder,T. Bag 원광대학교 기초자연과학연구소 2019 ANNALS OF FUZZY MATHEMATICS AND INFORMATICS Vol.18 No.3
In this paper, some basic results in complete fuzzy cone metric space are studied and Cantor's Intersection Theorem is established in fuzzy setting. On the other hand some results in compact fuzzy cone metric spaces are developed.

Pre clinical studies of Streblus asper Lour in terms of behavioural safety and toxicity
R. B. Suresh Kumar,A. Puratchikodi,Angelene Prasanna,Narayan Dolai,Piyali Majumder,U. K. Mazumder,P. K. Haldar 경희대학교 융합한의과학연구소 2011 Oriental Pharmacy and Experimental Medicine Vol.11 No.4
Streblus asper Lour (Family: Moraceae) is a medicinal plant wildly grows in most part of Asian countries. It has many traditional uses like leprosy, piles,diarrhoea, dysentery, elephantiasis, cancer etc. This present study was relates in terms of behavioural safety and toxicity studies of methanol and petroleum ether extracts of S. asper. Brine Shrimps lethality bioassay method was established for the present study and cytotoxicity was reported in terms of 50% lethality concentration (LC_(50)). Different concentrations of drug solutions were added to the Brine Shrimps, surviving shrimps were counted after 24 h and 50% lethality concentration (LC_(50)) were assessed. Acute toxicity was studied on Swiss albino mice after single dose. Sub-Chronic toxicity was performed for 28 days and assessed with biochemical and histopathological parameters. On cytotoxicity studies of brine shrimps it was found methanol extract of S. asper (MESA) was weakly toxic, may be due to the presence of cardiac glycosides and bioactive compounds, however petroleum ether extract of S. asper (PESA) was non toxic. But, in case of acute and sub-acute toxicity study both extracts were found to be non-toxic.
