Exploring cigarette butts pollution in Saint Martin Island: A marine protected area.

Saint Martin Island (SMI), the only coral island in Bangladesh, is located in the Bay of Bengal and has been identified as a marine protected area (MPA). Littering cigarette butts (CBs) waste in an ecologically sensitive environment can have numerous adverse effects. The purpose of this research is to investigate the abundance and density of CBs in SMI and to assess the pollution status using the Cigarette Butt Pollution Index (CBPI).

Nutrient content and degradation study of some unconventional feed resources of Bangladesh.

This study aimed to evaluate six unconventional feed resources of Bangladesh, including water hyacinth (), banana leaves (), roadside grass (), bamboo leaves ( Scrad), Seaweed ( sp.) and sugarcane bagasse (). Evaluations were based on dry matter (DM), crude protein (CP), crude fiber (CF), neutral detergent fiber (NDF), acid detergent fiber (ADF), ether extract (EE), ash content, DM and OM digestibilities and fractional rate of degradation.

Phytosociology and biodiversity of roadside herbs in a salinity-affected coastal area of Bangladesh.

Soil salinity in the coastal areas of Bangladesh has been rising. The responses of forest communities to the rise of salinity are somehow documented. However, the adjustments of non-forest plant communities against salinity are still limited in the literature.

Occurrence and molecular characterization of Cryptosporidium spp. and Giardia duodenalis among captive mammals in the Bangladesh National Zoo.

Cryptosporidium and Giardia are protozoan parasites capable of causing gastrointestinal illness in humans and animals. The purpose of this research was to determine the occurrence, genetic characteristics, and zoonotic potential of Cryptosporidium spp. and Giardia duodenalis in captive mammals at the Bangladesh National Zoo.

Development and assessment of a real-time pcr assay for rapid and sensitive detection of a novel thermotolerant bacterium, Lactobacillus thermotolerans, in chicken feces.

A new real-time PCR assay was successfully developed using a TaqMan fluorescence probe for specific detection and enumeration of a novel bacterium, Lactobacillus thermotolerans, in chicken feces. The specific primers and probe were designed based on the L. thermotolerans 16S rRNA gene sequences, and these sequences were compared to those of all available 16S rRNA genes in the GenBank database.

Sequence polymorphism and molecular characterization of laccase genes of the conifer pathogen Heterobasidion annosum.

The oxidizing enzyme laccase produced by many fungi is generally considered to be active in the biodegradation of lignin, a major plant cell wall component highly resistant to microbial attack. The enzyme is secreted at high levels by the P-type of the highly aggressive pathogen Heterobasidion annosum, but at much lower levels by the S-type which correlated with their varying wood decay capability. To investigate the evolutionary relationship between laccase genes of the different H.

Identification of Heterobasidion annosum (S-type) genes expressed during initial stages of conidiospore germination and under varying culture conditions.

Expressed sequence tag analysis (EST) is a robust approach for detecting novel and potentially important genes during fungal development. The technique was used in this study to identify and characterise genes induced during spore germination and hyphal morphogenesis under different culture conditions. For this study, a cDNA library was constructed from the germinated spores of S-type of Heterobasidion annosum.
