“…Morphological features have been widely used by most researchers for preliminary identification and placing of bacterial isolates into different morphotypes (Anna et al, 2018;Haldar and Nazareth, 2018;Saseeswari et al, 2016). Although useful, the information on morphological characters is insufficient to be used for final bacterial identification and, therefore, has to be supplemented with other data including the DNA relatedness studies, DNA-DNA hybridization, small subunit (SSU) sequences, cell wall composition and other characterization (Sarker et al, 2015).…”

“…Bacteria isolation was done according to Sarker et al [13] with modification on the medium. This study utilized a modified medium called MT with compositions such as, Peptone 0.2 %, Yeast Extract 0.1%, Meat Extract 0.1%, Calcium Carbonate (CaCO3) 0.1 %, Glucose 0.5%, Starch 0.5%, NaCl 0.2%, Agar 2.0%, and Nystatin.…”

The utilization of polysaccharide-degrading enzymes (EPEs) from bacteria has been increasing, therefore many studies are exploring new producers of EPEs. This study aimed to screen and identify the EPEs-producing marine sediment bacteria collected from Panjang Island, Jepara. A total of 11 bacteria were isolated from the sediment sample. Further, seven strains were selected to conduct further analysis, such as biochemical test and screening of enzyme activity. According to the calculation of enzyme activity index (EAI), it was noted that strain with given codes PP.K.15, PP.K.21, PP.K.6, and PP.K.20 demonstrated potential for carrageenase, alginate-lyase, amylase, and agarase. In addition, molecular identification using 16S rRNA gene sequencing discovered that PP.K.6 was identified as Basillus safensis, PP.K.11 as Sinomicrobium oceani, PP.K. 20 as Salinicola zeshunii, PP.K 15 and PP.K. 21 as Micrococcus luteus, and PP.K 22 as Qipengyuania flava.

“…All of these purified isolates were preserved on yeast-extract-glucose-agar slants at 4 o C. Then by using streak plate technique ( Alcamo et al, 2004) on yeastextract-glucose-agar medium, all of these pure isolates were preliminary screened for antibacterial activity. The isolate ANAM-39, a brownish yellow colored marine microorganism (Sarker et al, 2015) was chosen for further study based on testing antibacterial, antifungal and cytotoxic activities of metabolites of the strain since it showed highest antibacterial activity in preliminary antibacterial screening, visibility of the metabolite as well as excellent growth properties.…”

The present study was undertaken to screen the antimicrobial, antifungal and cytotoxic potentials of crude metabolite of a marine bacterium isolated from a soil sample collected from Sundarbans, Bangladesh. Primary and secondary screenings for antimicrobial activity were conducted by cross streak and agar well diffusion method, respectively. The antifungal potency of the crude extract was also tested by agar well-diffusion method. The brine shrimp lethality test was conducted to determine the cytotoxic nature of crude metabolites, which showed that the degree of lethality of metabolite was directly proportional to the concentration (LC 50 30.19 μg/ml). Further studies are needed to isolate and characterize the active principles present in the crude metabolite and determine their biological activity. The results of this investigation suggested that the soils of Sundarbans are rich sources of microorganisms with potent biological activities and systematic screening programs need to be conducted to explore the presence of pharmacologically active marine bacterial metabolites.
