“…Many microbes are found in mangrove forests, but studies are still needed to link microbial diversity and function as well as an assessment of how environmental changes can affect microbes [25]. Microbial diversity is an important aspect to study because of its potential to produce biomolecules that can be utilized by humans [26]. Bhitarkanika mangrove soil has a diversity of bacteria which is dominated by the genera Bacillus, Pseudomonas, Desulfotomaculum, Desulfovibrio, Desulfomonas, Methylococcus, Vibrio, Micrococcus, Klebsiella and Azotobacter [27].…”

Plastic waste can be seen in several areas in the Wonorejo mangrove forest, Surabaya, which is also a habitat for various types of microbes. Research on bacterial isolates from water samples in mangrove forests needs to be conducted to determine their diversity. This research was conducted to determine the diversity and dominance of bacterial isolates in mangrove forest waters. Each water sample was taken from a site that is regularly irrigated (station 1) and a site that is flooded (station 2). The number of bacteria in mangrove forest water samples was determined using the Total Plate Count (TPC) method and bacterial isolation was performed using the pour plate method. Subsequently, the bacterial isolates were characterized based on their colonies and observed for their dominance. The number of bacteria at station 1 was 4.85x102CFU/mL and 2.55x105 CFU/mL at station 2. Both stations showed bacterial diversity. However, several bacterial isolates with the same character can be found in both stations. Further research should be conducted to determine the potential of these bacterial isolates as plastic-degrading agents.

“…Despite much research in this field, the results are somewhat conflicting and confusing. For example, some use nutrient agar for the growth of total colony counts from mangrove soil (Kumar et al, 2007;Ambeng et al, 2019) while some use Tryptic Soya Agar (TSA) (Pupin and Nahas, 2014).In comparison, others preferred Zobell's marine agar (ZB agar), and synthetic seawater media (Sakhia et al, 2016;Saravanakumar et al, 2016;Schut et al, 1993). Our results suggested that the NA media is suitable for counting and isolating microbes from mangrove soil and sediments.…”

Mangrove are native to unique stressful habitat and mangrove-associated microbes may be one of the reasons behind the survival of this plant in this habitat. Therefore, it is necessary to explore the microbial diversity from the unstudied mangrove ecosystem because exploration of microbial associates of mangroves may help full to screen such potential specialized microbial strains that are as unique as their habitat. Samples of 8 different locations along the Arabian Gulf and the Red Sea were collected for enumeration and isolation of microbes based on different general and selective agar mediums. The results revealed that the maximum colony counts of total (1.01 × 107 CFU mean /g dry soil), fungi (1.18 × 104 CFU mean /g dry soil), and actinomycetes (5.93 × 104 CFU mean /g dry soil) were observed in L1 (MRS soil), L44 (MRS soil), and L3 (MRS soil) respectively. While minimum colony counts of total (5.32 × 104 CFU mean/g dry soil), fungi (2.59 × 102 CFU mean/g dry soil) and actinomycetes (2.61 × 10 CFU mean/g dry soil) were observed in L47 (MS soil), L3 (MS soil), and L4 (MS soil) respectively. L3 (MRS soil), L2 (MRS soil and MS soil), L1 (MRS soil), L44 (MRS soil), and L5 (NMRS soil and NMS soil) showed the growth of all studied groups of microbes other than sulfur oxidizers, while water samples, L3 (MSW water), L2 (MSW water), L47 (MSW water), L4 (MSW water), and L1 (MSW water) showed growth of limited groups as compared to soil samples.

“…Bacteria is one kind of microorganisms, there are two groups of bacteria, they are archaebacteria and eubacteria (Sattley & Madigan, 2015), moreover, eubacteria/bacteria is more common and has various kind of their own group. These bacteria can also live in the soil as a decomposer, such as decomposer in mangrove soil (Chen et al, 2016;Sakhia et al, 2016;Wu et al, 2016;Ambeng et al, 2019). Recent study shows that bacteria live in mangrove soil to decompose mangrove litter and constantly live at there due to condusive environment to them for living.…”

“…Recent study shows that bacteria live in mangrove soil to decompose mangrove litter and constantly live at there due to condusive environment to them for living. Some example mangrove bacteria are from genus Bacillus (Sakhia et al, 2016;Ambeng et al, 2019), Microccous, Yangia, Rhodococcus, Escherecia, Pseudotoromonas, Aerococcus, Pseudoteromonas (Sakhia et al, 2016), Staphylococcus, Vibrio, Alteromonas, Listeria, Macrococcus (Ambeng et al, 2019), Proteobacteria, Chloroflexi, Bacteriodetes, Planctomycetes (Wu et al, 2016). Those bacteria and mangrove soil can be potential learning sources for stundents.…”

Learning media is one of the most important component in a learning process, both inside or outside a classroom. In order to provide proper learning for students based on the researcher's prior research, at least, three different field tests are needed. This research is a quasi-experiment, which is provide result of the second field test of cellulose degrading bacteria from mangrove soil microbiology handout both in cognitive and psychomotor ability. The research aims are to describe effect of this microbiology handout on student's cognitive achievement and gain data about inappropriate laboratory written instruction in this handout. Data gained by conducting learning activities using developed handout which were 2 times in class theory and three times of practical activity using instuctions written in the handout. In the end of class theory activity, students did a posttest to confirm their improvement of cognitive ability while their practical ability was observed using observation sheet along with their activities. Results showed that handout which being tested could improve student cognitive at average level (n gain 0,419). In contrast, several parts of laboratory written instruction need to be fixed to make better microbiology handout.
