| 1 | Characterization and phylogenetic analysis of novel polyene type antimicrobial metabolite producing actinomycetes from marine sediments:Bay of Bengal India显示文摘Objective:To isolate and indentify the promising antimicrobial metabolite producing Streptomyces strains from marine sediment samples from Andraprudesh coast of India.Methods:Antagonistic aetinomycetes were isolated by starch casein agar medium and modified nutrient agar medium with 1%glucose used as a base for primary screening.Significant antimicrobial metabolite producing strains were selected and identified by using biochemical and 16S rDNA level.Minimum inhibitory concentrations of the organic extracts were done by using broth micro dilution method.Results:Among the 210 actinomyeetes,64.3%exhibited activity against Gram positive bacteria,48.5%showed activity towards Cram negative bacteria,38.8%exhibited both Cram positive and negative bacteria and 80.85%isolates revealed significant antifungal activity.However,five isolates AP-5,AP-18,AP-41 and AP-70 showed significant antimicrobial activity.The analysis of cell wall hydrolysates showed the presence of LL-diaminopimelic acid and glycine in all the isolates.Sequencing analysis indicated that the isolates shared 98.5%-99.8%sequence identity to the 16S rDNA gene sequences of the Streptomyces taxons.The antimicrobial substances were extracted using hexane and ethyl acetate from spent medium in which strains were cultivated at 30X for five days.The antimicrobial activity was assessed using broth micro dilution technique.Each of the culture extracts from these five strains showed a typical polyenelike property.The lowest minimum inhibitory concentrations of ethyl acetate extracts against Escherichia coli and Cumularia lunula were 67.5 and 125.0μg/mL,respectively.Conclusions:It can be concluded that hexane and ethyl acetate soluble extracellular products of novel isolates are effective against pathogenic bacteria and fungi. | Valan Arasu M Asha KRT Duraipandiyan V Ignacimuthu S Agastian P | 2012 | Asian Pacific Journal of Tropical Biomedicine2012，2，10： | 5 |

| 9 | Refined families of Dothideomycetes:orders and families incertae sedis in Dothideomycetes显示文摘Numerous new taxa and classifications of Dothideomycetes have been published following the last monograph of families of Dothideomycetes in 2013.A recent publication by Honsanan et al.in 2020 expanded information of families in Dothideo-mycetidae and Pleosporomycetidae with modern classifications.In this paper,we provide a refined updated document on orders and families incertae sedis of Dothideomycetes.Each family is provided with an updated description,notes,including figures to represent the morphology,a list of accepted genera,and economic and ecological significances.We also provide phylogenetic trees for each order.In this study,31 orders which consist 50 families are assigned as orders incertae sedis in Dothideomycetes,and 41 families are treated as families incertae sedis due to lack of molecular or morphological evidence.The new order,Catinellales,and four new families,Catinellaceae,Morenoinaceae Neobuelliellaceae and Thyrinulaceae are introduced.Seven genera(Neobuelliella,Pseudomicrothyrium,Flagellostrigula,Swinscowia,Macroconstrictolumina,Pseudobogoriella,and Schummia)are introduced.Seven new species(Acrospermum urticae,Bogoriella complexoluminata,Dothiorella ostryae,Dyfrolomyces distoseptatus,Macroconstrictolumina megalateralis,Patellaria microspora,and Pseu-domicrothyrium thailandicum)are introduced base on morphology and phylogeny,together with two new records/reports and five new collections from different families.Ninety new combinations are also provided in this paper. | Sinang Hongsanan Kevin D.Hyde Rungtiwa Phookamsak Dhanushka N.Wanasinghe Eric H.C.McKenzie V.Venkateswara Sarma Robert Lücking Saranyaphat Boonmee Jayarama D.Bhat Ning-Guo Liu Danushka S.Tennakoon Dhandevi Pem Anuruddha Karunarathna Shu-Hua Jiang Gareth E.B.Jones Alan J.L.Phillips Ishara S.Manawasinghe Saowaluck Tibpromma Subashini C.Jayasiri Diana Sandamali Ruvishika S.Jayawardena Nalin N.Wijayawardene Anusha H.Ekanayaka Rajesh Jeewon Yong-Zhong Lu Chayanard Phukhamsakda Asha J.Dissanayake Xiang-Yu Zeng Zong-Long Luo Qing Tian Kasun M.Thambugala Dongqin Dai Milan C.Samarakoon K.W.Thilini Chethana Damien Ertz Mingkwan Doilom Jian-Kui(Jack)Liu Sergio Pérez-Ortega Ave Suija Chanokned Senwanna Subodini N.Wijesinghe Mekala Niranjan Sheng-Nan Zhang Hiran A.Ariyawansa Hong-Bo Jiang Jin-Feng Zhang Chada Norphanphoun Nimali Ide Silva Vinodhini Thiyagaraja Huang Zhang Jadson D.P.Bezerra Ricardo Miranda-González AndréAptroot Hiroyuki Kashiwadani Dulanjalee Harishchandra Emmanuël Sérusiaux Pranami DAbeywickrama Dan-Feng Bao Bandarupalli Devadatha Hai-Xia Wu Kwang Hee Moon Cecile Gueidan Felix Schumm Digvijayini Bundhun Ausana Mapook Jutamart Monkai Chitrabhanu S.Bhunjun Putarak Chomnunti Satinee Suetrong Napalai Chaiwan Monika C.Dayarathne Jing Yang Achala R.Rathnayaka Jian-Chu Xu Jiesheng Zheng Gang Liu Yao Feng Ning Xie | 2020 | Fungal Diversity2020，，6： | 1 |
